- * jsmin.php - PHP implementation of Douglas Crockford's JSMin.

- * string as output.

- *

- * PHP 5 or higher is required.

- * Prado client-side javascript validation fascade.

- *

- * <p>There are 4 basic classes: {@link Prado.Validation}, 

- * {@link Prado.ValidationManager}, {@link Prado.WebUI.TValidationSummary}

- * and {@link Prado.WebUI.TBaseValidator}, 

- * that interact together to perform validation.

- * The {@link Prado.Validation} class co-ordinates together the

- * validation scheme and is responsible for maintaining references

- * to ValidationManagers.</p>

- *

- * <p>The {@link Prado.ValidationManager} class is responsible for 

- * maintaining refereneces

- * to individual validators, validation summaries and their associated

- * groupings.</p>

- *

- * <p>The {@link Prado.WebUI.TValidationSummary} takes care of displaying 

- * the validator error messages

- * as html output or an alert output.</p>

- *

- * <p>The {@link Prado.WebUI.TBaseValidator} is the base class for all 

- * validators and contains

- * methods to interact with the actual inputs, data type conversion.</p>

- *

- * <p>An instance of {@link Prado.ValidationManager} must be instantiated first for a

- * particular form before instantiating validators and summaries.</p>

- *

- * <p>Usage example: adding a required field to a text box input with

- * ID "input1" in a form with ID "form1".</p>

- * <pre>

- * &lt;script type="text/javascript" src="../prado.js"&gt;&lt;/script&gt;

- * &lt;script type="text/javascript" src="../validator.js"&gt;&lt;/script&gt;

- * &lt;form id="form1" action="..."&gt;

- * &lt;div&gt;

- * 	&lt;input type="text" id="input1" /&gt;

- *  &lt;span id="validator1" style="display:none; color:red"&gt;*&lt;/span&gt;

- *  &lt;input type="submit text="submit" /&gt;

- * &lt;script type="text/javascript"&gt;

- * new Prado.ValidationManager({FormID : 'form1'});

- * var options =

- * {

- *		ID :				'validator1',

- *		FormID :			'form1',

- *		ErrorMessage :		'*',

- *		ControlToValidate : 'input1'

- * }

- * new Prado.WebUI.TRequiredFieldValidator(options);

- * new Prado.WebUI.TValidationSummary({ID:'summary1',FormID:'form1'});

- *

- * //watch the form onsubmit event, check validators, stop if not valid.

- * Event.observe("form1", "submit" function(ev)

- * {

- * 	 if(Prado.WebUI.Validation.isValid("form1") == false)

- * 		Event.stop(ev);

- * });

- * &lt;/script&gt;

- * &lt;/div&gt;

- * &lt;/form&gt;

- * </pre>

+ * </code>
+ * where each JSON response is specified via a &lt;json&gt; element.
+ * Initial property values can be configured in a &lt;json&gt; element.
+ *
+ *
+ * PHP configuration style:
+ * <code>
+ *  'services' => array(

-/**

- * TPageService class.

- *

- * TPageService implements the service for serving user page requests.

- *

- * Pages that are available to client users are stored under a directory specified by

- * {@link setBasePath BasePath}. The directory may contain subdirectories.

- * Pages serving for a similar goal are usually placed under the same directory.

- * A directory may contain a configuration file <b>config.xml</b> whose content

- * is similar to that of application configuration file.

- *

- * A page is requested via page path, which is a dot-connected directory names

- * appended by the page name. Assume '<BasePath>/Users/Admin' is the directory

- * containing the page 'Update'. Then the page can be requested via 'Users.Admin.Update'.

- * By default, the {@link setBasePath BasePath} of the page service is the "pages"

- * directory under the application base path. You may change this default

- * by setting {@link setBasePath BasePath} with a different path you prefer.

- *

- * Page name refers to the file name (without extension) of the page template.

- * In order to differentiate from the common control template files, the extension

- * name of the page template files must be '.page'. If there is a PHP file with

- * the same page name under the same directory as the template file, that file

- * will be considered as the page class file and the file name is the page class name.

- * If such a file is not found, the page class is assumed as {@link TPage}.

- *

- * Modules can be configured and loaded in page directory configurations.

- * Configuration of a module in a subdirectory will overwrite its parent

- * directory's configuration, if both configurations refer to the same module.

- *

- * By default, TPageService will automatically load two modules:

- * - {@link TTemplateManager} : manages page and control templates

- * - {@link TThemeManager} : manages themes used in a Prado application

- *

- * In page directory configurations, static authorization rules can also be specified,

- * which governs who and which roles can access particular pages.

- * Refer to {@link TAuthorizationRule} for more details about authorization rules.

- * Page authorization rules can be configured within an <authorization> tag in

- * each page directory configuration as follows,

- * <authorization>

- *   <deny pages="Update" users="?" />

- *   <allow pages="Admin" roles="administrator" />

- *   <deny pages="Admin" users="*" />

- * </authorization>

- * where the 'pages' attribute may be filled with a sequence of comma-separated

- * page IDs. If 'pages' attribute does not appear in a rule, the rule will be

- * applied to all pages in this directory and all subdirectories (recursively).

- * Application of authorization rules are in a bottom-up fashion, starting from

- * the directory containing the requested page up to all parent directories.

- * The first matching rule will be used. The last rule always allows all users

- * accessing to any resources.

+/**
+ * TPageService class.
+ *
+ * TPageService implements the service for serving user page requests.
+ *
+ * Pages that are available to client users are stored under a directory specified by
+ * {@link setBasePath BasePath}. The directory may contain subdirectories.
+ * Pages serving for a similar goal are usually placed under the same directory.
+ * A directory may contain a configuration file <b>config.xml</b> whose content
+ * is similar to that of application configuration file.
+ *
+ * A page is requested via page path, which is a dot-connected directory names
+ * appended by the page name. Assume '<BasePath>/Users/Admin' is the directory
+ * containing the page 'Update'. Then the page can be requested via 'Users.Admin.Update'.
+ * By default, the {@link setBasePath BasePath} of the page service is the "pages"
+ * directory under the application base path. You may change this default
+ * by setting {@link setBasePath BasePath} with a different path you prefer.
+ *
+ * Page name refers to the file name (without extension) of the page template.
+ * In order to differentiate from the common control template files, the extension
+ * name of the page template files must be '.page'. If there is a PHP file with
+ * the same page name under the same directory as the template file, that file
+ * will be considered as the page class file and the file name is the page class name.
+ * If such a file is not found, the page class is assumed as {@link TPage}.
+ *
+ * Modules can be configured and loaded in page directory configurations.
+ * Configuration of a module in a subdirectory will overwrite its parent
+ * directory's configuration, if both configurations refer to the same module.
+ *
+ * By default, TPageService will automatically load two modules:
+ * - {@link TTemplateManager} : manages page and control templates
+ * - {@link TThemeManager} : manages themes used in a Prado application
+ *
+ * In page directory configurations, static authorization rules can also be specified,
+ * which governs who and which roles can access particular pages.
+ * Refer to {@link TAuthorizationRule} for more details about authorization rules.
+ * Page authorization rules can be configured within an <authorization> tag in
+ * each page directory configuration as follows,
+ * <authorization>
+ *   <deny pages="Update" users="?" />
+ *   <allow pages="Admin" roles="administrator" />
+ *   <deny pages="Admin" users="*" />
+ * </authorization>
+ * where the 'pages' attribute may be filled with a sequence of comma-separated
+ * page IDs. If 'pages' attribute does not appear in a rule, the rule will be
+ * applied to all pages in this directory and all subdirectories (recursively).
+ * Application of authorization rules are in a bottom-up fashion, starting from
+ * the directory containing the requested page up to all parent directories.
+ * The first matching rule will be used. The last rule always allows all users
+ * accessing to any resources.

-/**

- * TAssetManager class

- *

- * TAssetManager provides a scheme to allow web clients visiting

- * private files that are normally web-inaccessible.

- *

- * TAssetManager will copy the file to be published into a web-accessible

- * directory. The default base directory for storing the file is "assets", which

- * should be under the application directory. This can be changed by setting

- * the {@link setBasePath BasePath} property together with the

- * {@link setBaseUrl BaseUrl} property that refers to the URL for accessing the base path.

- *

- * By default, TAssetManager will not publish a file or directory if it already

- * exists in the publishing directory and has an older modification time.

- * If the application mode is set as 'Performance', the modification time check

- * will be skipped. You can explicitly require a modification time check

- * with the function {@link publishFilePath}. This is usually

- * very useful during development.

- *

- * TAssetManager may be configured in application configuration file as follows,

- * <code>

- * <module id="asset" BasePath="Application.assets" BaseUrl="/assets" />

- * </code>

- * where {@link getBasePath BasePath} and {@link getBaseUrl BaseUrl} are

- * configurable properties of TAssetManager. Make sure that BasePath is a namespace

- * pointing to a valid directory writable by the Web server process.

+ *
+ * TAssetManager provides a scheme to allow web clients visiting
+ * private files that are normally web-inaccessible.
+ *
+ * TAssetManager will copy the file to be published into a web-accessible
+ * directory. The default base directory for storing the file is "assets", which
+ * should be under the application directory. This can be changed by setting
+ * the {@link setBasePath BasePath} property together with the
+ * {@link setBaseUrl BaseUrl} property that refers to the URL for accessing the base path.
+ *
+ * By default, TAssetManager will not publish a file or directory if it already
+ * exists in the publishing directory and has an older modification time.
+ * If the application mode is set as 'Performance', the modification time check
+ * will be skipped. You can explicitly require a modification time check
+ * with the function {@link publishFilePath}. This is usually
+ * very useful during development.
+ *
+ * TAssetManager may be configured in application configuration file as follows,
+ * <code>
+ * <module id="asset" BasePath="Application.assets" BaseUrl="/assets" />
+ * </code>
+ * where {@link getBasePath BasePath} and {@link getBaseUrl BaseUrl} are
+ * configurable properties of TAssetManager. Make sure that BasePath is a namespace
+ * pointing to a valid directory writable by the Web server process.

-/**

- * THttpResponse class

- *

- * THttpResponse implements the mechanism for sending output to client users.

- *

- * To output a string to client, use {@link write()}. By default, the output is

- * buffered until {@link flush()} is called or the application ends. The output in

- * the buffer can also be cleaned by {@link clear()}. To disable output buffering,

- * set BufferOutput property to false.

- *

- * To send cookies to client, use {@link getCookies()}.

- * To redirect client browser to a new URL, use {@link redirect()}.

- * To send a file to client, use {@link writeFile()}.

- *

- * By default, THttpResponse is registered with {@link TApplication} as the

- * response module. It can be accessed via {@link TApplication::getResponse()}.

- *

- * THttpResponse may be configured in application configuration file as follows

- *

- * <module id="response" class="System.Web.THttpResponse" CacheExpire="20" CacheControl="nocache" BufferOutput="true" />

- *

- * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}

- * and {@link getBufferOutput BufferOutput} are optional properties of THttpResponse.

- *

- * THttpResponse sends charset header if either {@link setCharset() Charset}

- * or {@link TGlobalization::setCharset() TGlobalization.Charset} is set.

- *

- * Since 3.1.2, HTTP status code can be set with the {@link setStatusCode StatusCode} property.

- *

- * Note: Some HTTP Status codes can require additional header or body information. So, if you use {@link setStatusCode StatusCode}

- * in your application, be sure to add theses informations.

- * E.g : to make an http authentication :

- * <code>

- *  public function clickAuth ($sender, $param)

- *  {

- *     $response=$this->getResponse();

- *     $response->setStatusCode(401);

- *     $response->appendHeader('WWW-Authenticate: Basic realm="Test"');

- *  }

- * </code>

- *

- * This event handler will sent the 401 status code (Unauthorized) to the browser, with the WWW-Authenticate header field. This

- * will force the browser to ask for a username and a password.

- *

+/**
+ * THttpResponse class
+ *
+ * THttpResponse implements the mechanism for sending output to client users.
+ *
+ * To output a string to client, use {@link write()}. By default, the output is
+ * buffered until {@link flush()} is called or the application ends. The output in
+ * the buffer can also be cleaned by {@link clear()}. To disable output buffering,
+ * set BufferOutput property to false.
+ *
+ * To send cookies to client, use {@link getCookies()}.
+ * To redirect client browser to a new URL, use {@link redirect()}.
+ * To send a file to client, use {@link writeFile()}.
+ *
+ * By default, THttpResponse is registered with {@link TApplication} as the
+ * response module. It can be accessed via {@link TApplication::getResponse()}.
+ *
+ * THttpResponse may be configured in application configuration file as follows
+ *
+ * <module id="response" class="System.Web.THttpResponse" CacheExpire="20" CacheControl="nocache" BufferOutput="true" />
+ *
+ * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}
+ * and {@link getBufferOutput BufferOutput} are optional properties of THttpResponse.
+ *
+ * THttpResponse sends charset header if either {@link setCharset() Charset}
+ * or {@link TGlobalization::setCharset() TGlobalization.Charset} is set.
+ *
+ * Since 3.1.2, HTTP status code can be set with the {@link setStatusCode StatusCode} property.
+ *
+ * Note: Some HTTP Status codes can require additional header or body information. So, if you use {@link setStatusCode StatusCode}
+ * in your application, be sure to add theses informations.
+ * E.g : to make an http authentication :
+ * <code>
+ *  public function clickAuth ($sender, $param)
+ *  {
+ *     $response=$this->getResponse();
+ *     $response->setStatusCode(401);
+ *     $response->appendHeader('WWW-Authenticate: Basic realm="Test"');
+ *  }
+ * </code>
+ *
+ * This event handler will sent the 401 status code (Unauthorized) to the browser, with the WWW-Authenticate header field. This
+ * will force the browser to ask for a username and a password.

-/**

- * THttpSession class

- *

- * THttpSession provides session-level data management and the related configurations.

- * To start the session, call {@link open}; to complete and send out session data, call {@link close};

- * to destroy the session, call {@link destroy}. If AutoStart is true, then the session

- * will be started once the session module is loaded and initialized.

- *

- * To access data stored in session, use THttpSession like an associative array. For example,

- * <code>

- *   $session=new THttpSession;

- *   $session->open();

- *   $value1=$session['name1'];  // get session variable 'name1'

- *   $value2=$session['name2'];  // get session variable 'name2'

- *   foreach($session as $name=>$value) // traverse all session variables

- *   $session['name3']=$value3;  // set session variable 'name3'

- * </code>

- *

- * The following configurations are available for session:

- * {@link setAutoStart AutoStart}, {@link setCookieMode CookieMode},

- * {@link setSavePath SavePath},

- * {@link setUseCustomStorage UseCustomStorage}, {@link setGCProbability GCProbability},

- * {@link setTimeout Timeout}.

- * See the corresponding setter and getter documentation for more information.

- * Note, these properties must be set before the session is started.

- *

- * THttpSession can be inherited with customized session storage method.

- * Override {@link _open}, {@link _close}, {@link _read}, {@link _write}, {@link _destroy} and {@link _gc}

- * and set {@link setUseCustomStorage UseCustomStorage} to true.

- * Then, the session data will be stored using the above methods.

- *

- * By default, THttpSession is registered with {@link TApplication} as the

- * request module. It can be accessed via {@link TApplication::getSession()}.

- *

- * THttpSession may be configured in application configuration file as follows,

- * <code>

- * <module id="session" class="THttpSession" SessionName="SSID" SavePath="/tmp"

- *         CookieMode="Allow" UseCustomStorage="false" AutoStart="true" GCProbability="1"

- *         UseTransparentSessionID="true" TimeOut="3600" />

- * </code>

- * where {@link getSessionName SessionName}, {@link getSavePath SavePath},

- * {@link getCookieMode CookieMode}, {@link getUseCustomStorage

- * UseCustomStorage}, {@link getAutoStart AutoStart}, {@link getGCProbability

- * GCProbability}, {@link getUseTransparentSessionID UseTransparentSessionID}

- * and {@link getTimeout TimeOut} are configurable properties of THttpSession.

- *

- * @package System.Web

- * @since 3.0

+/**
+ * THttpSession class
+ *
+ * THttpSession provides session-level data management and the related configurations.
+ * To start the session, call {@link open}; to complete and send out session data, call {@link close};
+ * to destroy the session, call {@link destroy}. If AutoStart is true, then the session
+ * will be started once the session module is loaded and initialized.
+ *
+ * To access data stored in session, use THttpSession like an associative array. For example,
+ * <code>
+ *   $session=new THttpSession;
+ *   $session->open();
+ *   $value1=$session['name1'];  // get session variable 'name1'
+ *   $value2=$session['name2'];  // get session variable 'name2'
+ *   foreach($session as $name=>$value) // traverse all session variables
+ *   $session['name3']=$value3;  // set session variable 'name3'
+ * </code>
+ *
+ * The following configurations are available for session:
+ * {@link setAutoStart AutoStart}, {@link setCookieMode CookieMode},
+ * {@link setSavePath SavePath},
+ * {@link setUseCustomStorage UseCustomStorage}, {@link setGCProbability GCProbability},
+ * {@link setTimeout Timeout}.
+ * See the corresponding setter and getter documentation for more information.
+ * Note, these properties must be set before the session is started.
+ *
+ * THttpSession can be inherited with customized session storage method.
+ * Override {@link _open}, {@link _close}, {@link _read}, {@link _write}, {@link _destroy} and {@link _gc}
+ * and set {@link setUseCustomStorage UseCustomStorage} to true.
+ * Then, the session data will be stored using the above methods.
+ *
+ * By default, THttpSession is registered with {@link TApplication} as the
+ * request module. It can be accessed via {@link TApplication::getSession()}.
+ *
+ * THttpSession may be configured in application configuration file as follows,
+ * <code>
+ * <module id="session" class="THttpSession" SessionName="SSID" SavePath="/tmp"
+ *         CookieMode="Allow" UseCustomStorage="false" AutoStart="true" GCProbability="1"
+ *         UseTransparentSessionID="true" TimeOut="3600" />
+ * </code>
+ * where {@link getSessionName SessionName}, {@link getSavePath SavePath},
+ * {@link getCookieMode CookieMode}, {@link getUseCustomStorage
+ * UseCustomStorage}, {@link getAutoStart AutoStart}, {@link getGCProbability
+ * GCProbability}, {@link getUseTransparentSessionID UseTransparentSessionID}
+ * and {@link getTimeout TimeOut} are configurable properties of THttpSession.

- * be used to decompose the URL into request parameters (accessible through

- * <code>$this->Request['paramname']</code>).

- *

- * The patterns can also be used to construct customized URLs. In this case,

- * the parameters in an applied pattern will be replaced with the corresponding

- * GET variable values.

- *

- * Since it is derived from {@link TUrlManager}, it should be configured globally

- * in the application configuration like the following,

- * <code>

- *  <module id="request" class="THttpRequest" UrlManager="friendly-url" />

- *  <module id="friendly-url" class="System.Web.TUrlMapping" EnableCustomUrl="true">

- *    <url ServiceParameter="Posts.ViewPost" pattern="post/{id}/" parameters.id="\d+" />

- *    <url ServiceParameter="Posts.ListPost" pattern="archive/{time}/" parameters.time="\d{6}" />

- *    <url ServiceParameter="Posts.ListPost" pattern="category/{cat}/" parameters.cat="\d+" />

- *  </module>

- * </code>

- *

- * In the above, each <tt>&lt;url&gt;</tt> element specifies a URL pattern represented

- * as a {@link TUrlMappingPattern} internally. You may create your own pattern classes

- * by extending {@link TUrlMappingPattern} and specifying the <tt>&lt;class&gt;</tt> attribute

- * in the element.

- *

- * The patterns can be also be specified in an external file using the {@link setConfigFile ConfigFile} property.

- *

- * The URL mapping are evaluated in order, only the first mapping that matches

- * the URL will be used. Cascaded mapping can be achieved by placing the URL mappings

- * in particular order. For example, placing the most specific mappings first.

- *

- * Only the PATH_INFO part of the URL is used to match the available patterns. The matching

- * is strict in the sense that the whole pattern must match the whole PATH_INFO of the URL.

- *

- * From PRADO v3.1.1, TUrlMapping also provides support for constructing URLs according to

- * the specified pattern. You may enable this functionality by setting {@link setEnableCustomUrl EnableCustomUrl} to true.

- * When you call THttpRequest::constructUrl() (or via TPageService::constructUrl()),

- * TUrlMapping will examine the available URL mapping patterns using their {@link TUrlMappingPattern::getServiceParameter ServiceParameter}

- * and {@link TUrlMappingPattern::getPattern Pattern} properties. A pattern is applied if its

- * {@link TUrlMappingPattern::getServiceParameter ServiceParameter} matches the service parameter passed

- * to constructUrl() and every parameter in the {@link getPattern Pattern} is found

- * in the GET variables.

-/**

- * TUrlMappingPattern class.

- *

- * TUrlMappingPattern represents a pattern used to parse and construct URLs.

- * If the currently requested URL matches the pattern, it will alter

- * the THttpRequest parameters. If a constructUrl() call matches the pattern

- * parameters, the pattern will generate a valid URL. In both case, only the PATH_INFO

- * part of a URL is parsed/constructed using the pattern.

- *

- * To specify the pattern, set the {@link setPattern Pattern} property.

- * {@link setPattern Pattern} takes a string expression with

- * parameter names enclosed between a left brace '{' and a right brace '}'.

- * The patterns for each parameter can be set using {@link getParameters Parameters}

- * attribute collection. For example

- * <code>

- * <url ... pattern="articles/{year}/{month}/{day}"

- *          parameters.year="\d{4}" parameters.month="\d{2}" parameters.day="\d+" />

- * </code>

- *

- * In the above example, the pattern contains 3 parameters named "year",

- * "month" and "day". The pattern for these parameters are, respectively,

- * "\d{4}" (4 digits), "\d{2}" (2 digits) and "\d+" (1 or more digits).

- * Essentially, the <tt>Parameters</tt> attribute name and values are used

- * as substrings in replacing the placeholders in the <tt>Pattern</tt> string

- * to form a complete regular expression string.

- *

- * For more complicated patterns, one may specify the pattern using a regular expression

- * by {@link setRegularExpression RegularExpression}. For example, the above pattern

- * is equivalent to the following regular expression-based pattern:

- * <code>

- * #^articles/(?P<year>\d{4})/(?P<month>\d{2})\/(?P<day>\d+)$#u

- * </code>

- * The above regular expression used the "named group" feature available in PHP.

- * If you intended to use the <tt>RegularExpression</tt> property or

- * regular expressions in CDATA sections, notice that you need to escape the slash,

- * if you are using the slash as regular expressions delimiter.

- *

- * Thus, only an url that matches the pattern will be valid. For example,

- * a URL <tt>http://example.com/index.php/articles/2006/07/21</tt> will match the above pattern,

- * while <tt>http://example.com/index.php/articles/2006/07/hello</tt> will not

- * since the "day" parameter pattern is not satisfied.

- *

- * The parameter values are available through the <tt>THttpRequest</tt> instance (e.g.

- * <tt>$this->Request['year']</tt>).

- *

- * The {@link setServiceParameter ServiceParameter} and {@link setServiceID ServiceID}

- * (the default ID is 'page') set the service parameter and service id respectively.

-/**

- * TAutoComplete class.

- *

- * TAutoComplete is a textbox that provides a list of suggestion on

- * the current partial word typed in the textbox. The suggestions are

- * requested using callbacks, and raises the {@link onSuggestion OnSuggestion}

- * event. The events of the TActiveText (from which TAutoComplete is extended from)

- * and {@link onSuggestion OnSuggestion} are mutually exculsive. That is,

- * if {@link onTextChange OnTextChange} and/or {@link onCallback OnCallback}

- * events are raise, then {@link onSuggestion OnSuggestion} will not be raise, and

- * vice versa.

- *

- * The list of suggestions should be set in the {@link onSuggestion OnSuggestion}

- * event handler. The partial word to match the suggestion is in the

- * {@link TCallbackEventParameter::getCallbackParameter TCallbackEventParameter::CallbackParameter}

- * property. The datasource of the TAutoComplete must be set using {@link setDataSource}

- * method. This sets the datasource for the suggestions repeater, available through

- * the {@link getSuggestions Suggestions} property. Header, footer templates and

- * other properties of the repeater can be access via the {@link getSuggestions Suggestions}

- * property and its sub-properties.

- *

- * The {@link setTextCssClass TextCssClass} property if set is used to find

- * the element within the Suggestions.ItemTemplate and Suggestions.AlternatingItemTemplate

- * that contains the actual text for the suggestion selected. That is,

- * only text inside elements with CSS class name equal to {@link setTextCssClass TextCssClass}

- * will be used as suggestions.

- *

- * To return the list of suggestions back to the browser, supply a non-empty data source

- * and call databind. For example,

- * <code>

- * function autocomplete_suggestion($sender, $param)

- * {

- *   $token = $param->getToken(); //the partial word to match

- *   $sender->setDataSource($this->getSuggestionsFor($token)); //set suggestions

- *   $sender->dataBind();

- * }

- * </code>

- *

- * The suggestion will be rendered when the {@link dataBind()} method is called

- * <strong>during a callback request</strong>.

- *

- * When an suggestion is selected, that is, when the use has clicked, pressed

- * the "Enter" key, or pressed the "Tab" key, the {@link onSuggestionSelected OnSuggestionSelected}

- * event is raised. The

- * {@link TCallbackEventParameter::getCallbackParameter TCallbackEventParameter::CallbackParameter}

- * property contains the index of the selected suggestion.

- *

- * TAutoComplete allows multiple suggestions within one textbox with each

- * word or phrase separated by any characters specified in the

- * {@link setSeparator Separator} property. The {@link setFrequency Frequency}

- * and {@link setMinChars MinChars} properties sets the delay and minimum number

- * of characters typed, respectively, before requesting for sugggestions.

- *

- * Use {@link onTextChange OnTextChange} and/or {@link onCallback OnCallback} events

- * to handle post backs due to {@link setAutoPostBack AutoPostBack}.

- *

- * In the {@link getSuggestions Suggestions} TRepater item template, all HTML text elements

- * are considered as text for the suggestion. Text within HTML elements with CSS class name

- * "informal" are ignored as text for suggestions.

- * TCallbackClientSide class.

- *

- * The following client side events are executing in order if the callback

- * request and response are send and received successfuly.

- *

- * - <b>onPreDispatch</b> executed before a request is dispatched.

- * - <b>onUninitialized</b> executed when callback request is uninitialized.

- * - <b>onLoading</b>* executed when callback request is initiated

- * - <b>onLoaded</b>* executed when callback request begins.

- * - <b>onInteractive</b> executed when callback request is in progress.

- * - <b>onComplete</b>executed when callback response returns.

- * - <b>onSuccess</b> executed when callback request returns and is successful.

- * - <b>onFailure</b> executed when callback request returns and fails.

- * - <b>onException</b> raised when callback request fails due to request/response errors.

- *

- * * Note that theses 2 events are not fired correctly by Opera. To make

- *   them work in this browser, Prado will fire them just after onPreDispatch.

- * 

- * In a general way, onUninitialized, onLoading, onLoaded and onInteractive events 

- * are not implemented consistently in all browsers.When cross browser compatibility is

- * needed, it is best to avoid use them

- *

- * The OnSuccess and OnFailure events are raised when the

- * response is returned. A successful request/response will raise

- * OnSuccess event otherwise OnFailure will be raised.

- *

- * - <b>PostState</b> true to collect the form inputs and post them during callback, default is true.

- * - <b>RequestTimeOut</b> The request timeout in milliseconds.

- * - <b>HasPriority</b> true to ensure that the callback request will be sent

- *   immediately and will abort existing prioritized requests. It does not affect

- *   callbacks that are not prioritized.

- * - <b>EnablePageStateUpdate</b> enable the callback response to enable the

- *   viewstate update. This will automatically set HasPriority to true when enabled.

- * TInPlaceTextBox Class

- * TInPlaceTextBox is a component rendered as a label and allows its

- * contents to be edited by changing the label to a textbox when

- * the label is clicked or when another control or html element with

- * ID given by {@link setEditTriggerControlID EditTriggerControlID} is clicked.

- *

- * If the {@link OnLoadingText} event is handled, a callback request is

- * made when the label is clicked, while the request is being made the

- * textbox is disabled from editing. The {@link OnLoadingText} event allows

- * you to update the content of the textbox before the client is allowed

- * to edit the content. After the callback request returns successfully,

- * the textbox is enabled and the contents is then allowed to be edited.

- *

- * Once the textbox loses focus, if {@link setAutoPostBack AutoPostBack}

- * is true and the textbox content has changed, a callback request is made and

- * the {@link OnTextChanged} event is raised like that of the TActiveTextBox.

- * During the request, the textbox is disabled.

- *

- * After the callback request returns sucessfully, the textbox is enabled.

- * If the {@link setAutoHideTextBox AutoHideTextBox} property is true, then

- * the textbox will be hidden and the label is then shown.

- *

- * Since 3.1.2, you can set the {@link setReadOnly ReadOnly} property to make

- * the control not editable. This property can be also changed on callback

+ * ID given by {@link setEditTriggerControlID EditTriggerControlID} is clicked.
+ *

+ * you to update the content of the textbox before the client is allowed
+ * to edit the content. After the callback request returns successfully,
+ * the textbox is enabled and the contents is then allowed to be edited.
+ *
+ * Once the textbox loses focus, if {@link setAutoPostBack AutoPostBack}
+ * is true and the textbox content has changed, a callback request is made and
+ * the {@link OnTextChanged} event is raised like that of the TActiveTextBox.
+ * During the request, the textbox is disabled.
+ *
+ * After the callback request returns sucessfully, the textbox is enabled.
+ * If the {@link setAutoHideTextBox AutoHideTextBox} property is true, then
+ * the textbox will be hidden and the label is then shown.
+ *
+ * Since 3.1.2, you can set the {@link setReadOnly ReadOnly} property to make
+ * the control not editable. This property can be also changed on callback

-/**

- * TCachePageStatePersister class

- *

- * TCachePageStatePersister implements a page state persistent method based on cache.

- * Page state are stored in cache (e.g. memcache, DB cache, etc.), and only a small token

- * is passed to the client side to identify the state. This greatly reduces the size of

- * the page state that needs to be transmitted between the server and the client. Of course,

- * this is at the cost of using server side resource.

- *

- * A cache module has to be loaded in order to use TCachePageStatePersister.

- * By default, TCachePageStatePersister will use the primary cache module.

- * A non-primary cache module can be used by setting {@link setCacheModuleID CacheModuleID}.

- * Any cache module, as long as it implements the interface {@link ICache}, may be used.

- * For example, one can use {@link TDbCache}, {@link TMemCache}, {@link TAPCCache}, etc.

- *

- * TCachePageStatePersister uses {@link setCacheTimeout CacheTimeout} to limit the data

- * that stores in cache.

- *

- * Since server resource is often limited, be cautious if you plan to use TCachePageStatePersister

- * for high-traffic Web pages. You may consider using a small {@link setCacheTimeout CacheTimeout}.

- *

- * There are a couple of ways to use TCachePageStatePersister.

- * One can override the page's {@link TPage::getStatePersister()} method and

- * create a TCachePageStatePersister instance there.

- * Or one can configure the pages to use TCachePageStatePersister in page configurations

- * as follows,

- * <code>

- *   <pages StatePersisterClass="System.Web.UI.TCachePageStatePersister"

- *          StatePersister.CacheModuleID="mycache"

- *          StatePersister.CacheTimeout="3600" />

- * </code>

- * Note in the above, we use StatePersister.CacheModuleID to configure the cache module ID

- * for the TCachePageStatePersister instance.

- *

- * The above configuration will affect the pages under the directory containing

- * this configuration and all its subdirectories.

- * To configure individual pages to use TCachePageStatePersister, use

- * <code>

- *   <pages>

- *     <page id="PageID" StatePersisterClass="System.Web.UI.TCachePageStatePersister" />

- *   </pages>

- * </code>

-/**

- * TControl class

- *

- * TControl is the base class for all components on a page hierarchy.

- * It implements the following features for UI-related functionalities:

- * - databinding feature

- * - parent and child relationship

- * - naming container and containee relationship

- * - viewstate and controlstate features

- * - rendering scheme

- * - control lifecycles

- *

- * A property can be data-bound with an expression. By calling {@link dataBind},

- * expressions bound to properties will be evaluated and the results will be

- * set to the corresponding properties.

- *

- * Parent and child relationship determines how the presentation of controls are

- * enclosed within each other. A parent will determine where to place

- * the presentation of its child controls. For example, a TPanel will enclose

- * all its child controls' presentation within a div html tag. A control's parent

- * can be obtained via {@link getParent Parent} property, and its

- * {@link getControls Controls} property returns a list of the control's children,

- * including controls and static texts. The property can be manipulated

- * like an array for adding or removing a child (see {@link TList} for more details).

- *

- * A naming container control implements INamingContainer and ensures that

- * its containee controls can be differentiated by their ID property values.

- * Naming container and containee realtionship specifies a protocol to uniquely

- * identify an arbitrary control on a page hierarchy by an ID path (concatenation

- * of all naming containers' IDs and the target control's ID).

- *

- * Viewstate and controlstate are two approaches to preserve state across

- * page postback requests. ViewState is mainly related with UI specific state

- * and can be disabled if not needed. ControlState represents crucial logic state

- * and cannot be disabled.

- *

- * A control is rendered via its {@link render()} method (the method is invoked

- * by the framework.) Descendant control classes may override this method for

- * customized rendering. By default, {@link render()} invokes {@link renderChildren()}

- * which is responsible for rendering of children of the control.

- * Control's {@link getVisible Visible} property governs whether the control

- * should be rendered or not.

- *

- * Each control on a page will undergo a series of lifecycles, including

- * control construction, Init, Load, PreRender, Render, and OnUnload.

- * They work together with page lifecycles to process a page request.

+/**
+ * TControl class
+ *
+ * TControl is the base class for all components on a page hierarchy.
+ * It implements the following features for UI-related functionalities:
+ * - databinding feature
+ * - parent and child relationship
+ * - naming container and containee relationship
+ * - viewstate and controlstate features
+ * - rendering scheme
+ * - control lifecycles
+ *
+ * A property can be data-bound with an expression. By calling {@link dataBind},
+ * expressions bound to properties will be evaluated and the results will be
+ * set to the corresponding properties.
+ *
+ * Parent and child relationship determines how the presentation of controls are
+ * enclosed within each other. A parent will determine where to place
+ * the presentation of its child controls. For example, a TPanel will enclose
+ * all its child controls' presentation within a div html tag. A control's parent
+ * can be obtained via {@link getParent Parent} property, and its
+ * {@link getControls Controls} property returns a list of the control's children,
+ * including controls and static texts. The property can be manipulated
+ * like an array for adding or removing a child (see {@link TList} for more details).
+ *
+ * A naming container control implements INamingContainer and ensures that
+ * its containee controls can be differentiated by their ID property values.
+ * Naming container and containee realtionship specifies a protocol to uniquely
+ * identify an arbitrary control on a page hierarchy by an ID path (concatenation
+ * of all naming containers' IDs and the target control's ID).
+ *
+ * Viewstate and controlstate are two approaches to preserve state across
+ * page postback requests. ViewState is mainly related with UI specific state
+ * and can be disabled if not needed. ControlState represents crucial logic state
+ * and cannot be disabled.
+ *
+ * A control is rendered via its {@link render()} method (the method is invoked
+ * by the framework.) Descendant control classes may override this method for
+ * customized rendering. By default, {@link render()} invokes {@link renderChildren()}
+ * which is responsible for rendering of children of the control.
+ * Control's {@link getVisible Visible} property governs whether the control
+ * should be rendered or not.
+ *
+ * Each control on a page will undergo a series of lifecycles, including
+ * control construction, Init, Load, PreRender, Render, and OnUnload.
+ * They work together with page lifecycles to process a page request.

-/**

- * TTemplate implements PRADO template parsing logic.

- * A TTemplate object represents a parsed PRADO control template.

- * It can instantiate the template as child controls of a specified control.

- * The template format is like HTML, with the following special tags introduced,

- * - component tags: a component tag represents the configuration of a component.

- * The tag name is in the format of com:ComponentType, where ComponentType is the component

- * class name. Component tags must be well-formed. Attributes of the component tag

- * are treated as either property initial values, event handler attachment, or regular

- * tag attributes.

- * - property tags: property tags are used to set large block of attribute values.

- * The property tag name is in the format of <prop:AttributeName> where AttributeName

- * can be a property name, an event name or a regular tag attribute name.

- * - group subproperty tags: subproperties of a common property can be configured using

- * <prop:MainProperty SubProperty1="Value1" SubProperty2="Value2" .../>

- * - directive: directive specifies the property values for the template owner.

- * It is in the format of <%@ property name-value pairs %>;

- * - expressions: They are in the format of <%= PHP expression %> and <%% PHP statements %>

- * - comments: There are two kinds of comments, regular HTML comments and special template comments.

- * The former is in the format of <!-- comments -->, which will be treated as text strings.

- * The latter is in the format of <!-- comments --!>, which will be stripped out.

- *

- * Tags other than the above are not required to be well-formed.

- *

- * A TTemplate object represents a parsed PRADO template. To instantiate the template

- * for a particular control, call {@link instantiateIn($control)}, which

- * will create and intialize all components specified in the template and

- * set their parent as $control.

+/**
+ * TTemplate implements PRADO template parsing logic.
+ * A TTemplate object represents a parsed PRADO control template.
+ * It can instantiate the template as child controls of a specified control.
+ * The template format is like HTML, with the following special tags introduced,
+ * - component tags: a component tag represents the configuration of a component.
+ * The tag name is in the format of com:ComponentType, where ComponentType is the component
+ * class name. Component tags must be well-formed. Attributes of the component tag
+ * are treated as either property initial values, event handler attachment, or regular
+ * tag attributes.
+ * - property tags: property tags are used to set large block of attribute values.
+ * The property tag name is in the format of <prop:AttributeName> where AttributeName
+ * can be a property name, an event name or a regular tag attribute name.
+ * - group subproperty tags: subproperties of a common property can be configured using
+ * <prop:MainProperty SubProperty1="Value1" SubProperty2="Value2" .../>
+ * - directive: directive specifies the property values for the template owner.
+ * It is in the format of <%@ property name-value pairs %>;
+ * - expressions: They are in the format of <%= PHP expression %> and <%% PHP statements %>
+ * - comments: There are two kinds of comments, regular HTML comments and special template comments.
+ * The former is in the format of <!-- comments -->, which will be treated as text strings.
+ * The latter is in the format of <!-- comments --!>, which will be stripped out.
+ *
+ * Tags other than the above are not required to be well-formed.
+ *
+ * A TTemplate object represents a parsed PRADO template. To instantiate the template
+ * for a particular control, call {@link instantiateIn($control)}, which
+ * will create and intialize all components specified in the template and
+ * set their parent as $control.

- * TThemeManager manages the themes used in a Prado application.

- *

- * Themes are stored under the directory specified by the

- * via URL {@link setBaseUrl BaseUrl}. Each theme is represented by a subdirectory

- * and all the files under that directory. The name of a theme is the name

- * of the corresponding subdirectory.

- * By default, the base path of all themes is a directory named "themes"

- * under the directory containing the application entry script.

- * To get a theme (normally you do not need to), call {@link getTheme}.

- *

- * TThemeManager may be configured within page service tag in application

- * configuration file as follows,

- * <module id="themes" class="System.Web.UI.TThemeManager"

- *         BasePath="Application.themes" BaseUrl="/themes" />

- * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}

- * and {@link getBufferOutput BufferOutput} are configurable properties of THttpResponse.

-/**

- * Class TAccordion.

- *

- * TAccordion displays an accordion control. Users can click on the view headers to switch among

- * different accordion views. Each accordion view is an independent panel that can contain arbitrary content.

- *

- * A TAccordion control consists of one or several {@link TAccordionView} controls representing the possible

- * accordion views. At any time, only one accordion view is visible (active), which is specified by any of

- * the following properties:

- * - {@link setActiveViewIndex ActiveViewIndex} - the zero-based integer index of the view in the view collection.

- * - {@link setActiveViewID ActiveViewID} - the text ID of the visible view.

- * - {@link setActiveView ActiveView} - the visible view instance.

- * If both {@link setActiveViewIndex ActiveViewIndex} and {@link setActiveViewID ActiveViewID}

- * are set, the latter takes precedence.

- *

- * TAccordion uses CSS to specify the appearance of the accordion headers and panel. By default,

- * an embedded CSS file will be published which contains the default CSS for TTabPanel.

- * You may also use your own CSS file by specifying the {@link setCssUrl CssUrl} property.

- * The following properties specify the CSS classes used for elements in a TAccordion:

- * - {@link setCssClass CssClass} - the CSS class name for the outer-most div element (defaults to 'accordion');

- * - {@link setHeaderCssClass HeaderCssClass} - the CSS class name for nonactive accordion div elements (defaults to 'accordion-header');

- * - {@link setActiveHeaderCssClass ActiveHeaderCssClass} - the CSS class name for the active accordion div element (defaults to 'accordion-header-active');

- * - {@link setViewCssClass ViewCssClass} - the CSS class for the div element enclosing view content (defaults to 'accordion-view');

- *

- * When the user clicks on a view header, the switch between the old visible view and the clicked one is animated.

- * You can use the {@link setAnimationDuration AnimationDuration} property to set the animation length in seconds;

- * it defaults to 1 second, and when set to 0 it will produce an immediate switch with no animation.

- *

- * The TAccordion auto-sizes itself to the largest of all views, so it can encompass all of them without scrolling.

- * If you want to specify a fixed height (in pixels), use the {@link setViewHeight ViewHeight} property.

- * When a TAccordion is nested inside another, it's adviced to manually specify a {@link setViewHeight ViewHeight} for the internal TAccordion

- *

- * To use TAccordion, write a template like following:

- * <code>

- * <com:TAccordion>

- *   <com:TAccordionView Caption="View 1">

- *     content for view 1

- *   </com:TAccordionView>

- *   <com:TAccordionView Caption="View 2">

- *     content for view 2

- *   </com:TAccordionView>

- *   <com:TAccordionView Caption="View 3">

- *     content for view 3

- *   </com:TAccordionView>

- * </com:TAccordion>

- * </code>

+/**
+ * Class TAccordion.
+ *
+ * TAccordion displays an accordion control. Users can click on the view headers to switch among
+ * different accordion views. Each accordion view is an independent panel that can contain arbitrary content.
+ *
+ * A TAccordion control consists of one or several {@link TAccordionView} controls representing the possible
+ * accordion views. At any time, only one accordion view is visible (active), which is specified by any of
+ * the following properties:
+ * - {@link setActiveViewIndex ActiveViewIndex} - the zero-based integer index of the view in the view collection.
+ * - {@link setActiveViewID ActiveViewID} - the text ID of the visible view.
+ * - {@link setActiveView ActiveView} - the visible view instance.
+ * If both {@link setActiveViewIndex ActiveViewIndex} and {@link setActiveViewID ActiveViewID}
+ * are set, the latter takes precedence.
+ *
+ * TAccordion uses CSS to specify the appearance of the accordion headers and panel. By default,
+ * an embedded CSS file will be published which contains the default CSS for TTabPanel.
+ * You may also use your own CSS file by specifying the {@link setCssUrl CssUrl} property.
+ * The following properties specify the CSS classes used for elements in a TAccordion:
+ * - {@link setCssClass CssClass} - the CSS class name for the outer-most div element (defaults to 'accordion');
+ * - {@link setHeaderCssClass HeaderCssClass} - the CSS class name for nonactive accordion div elements (defaults to 'accordion-header');
+ * - {@link setActiveHeaderCssClass ActiveHeaderCssClass} - the CSS class name for the active accordion div element (defaults to 'accordion-header-active');
+ * - {@link setViewCssClass ViewCssClass} - the CSS class for the div element enclosing view content (defaults to 'accordion-view');
+ *
+ * When the user clicks on a view header, the switch between the old visible view and the clicked one is animated.
+ * You can use the {@link setAnimationDuration AnimationDuration} property to set the animation length in seconds;
+ * it defaults to 1 second, and when set to 0 it will produce an immediate switch with no animation.
+ *
+ * The TAccordion auto-sizes itself to the largest of all views, so it can encompass all of them without scrolling.
+ * If you want to specify a fixed height (in pixels), use the {@link setViewHeight ViewHeight} property.
+ * When a TAccordion is nested inside another, it's adviced to manually specify a {@link setViewHeight ViewHeight} for the internal TAccordion
+ *
+ * To use TAccordion, write a template like following:
+ * <code>
+ * <com:TAccordion>
+ *   <com:TAccordionView Caption="View 1">
+ *     content for view 1
+ *   </com:TAccordionView>
+ *   <com:TAccordionView Caption="View 2">
+ *     content for view 2
+ *   </com:TAccordionView>
+ *   <com:TAccordionView Caption="View 3">
+ *     content for view 3
+ *   </com:TAccordionView>
+ * </com:TAccordion>
+ * </code>

-/**

- * TBoundColumn class

- *

- * TBoundColumn represents a column that is bound to a field in a data source.

- * The cells in the column will be displayed using the data indexed by

- * {@link setDataField DataField}. You can customize the display by

- * setting {@link setDataFormatString DataFormatString}.

- *

- * If {@link setReadOnly ReadOnly} is false, TBoundColumn will display cells in edit mode

- * with textboxes. Otherwise, a static text is displayed.

- *

- * When a datagrid row is in edit mode, the textbox control in the TBoundColumn

- * can be accessed by one of the following two methods:

- * <code>

- * $datagridItem->BoundColumnID->TextBox

- * $datagridItem->BoundColumnID->Controls[0]

- * </code>

- * The second method is possible because the textbox control created within the

- * datagrid cell is the first child.

- *

- * Since v3.1.0, TBoundColumn has introduced two new properties {@link setItemRenderer ItemRenderer}

- * and {@link setEditItemRenderer EditItemRenderer} which can be used to specify

- * the layout of the datagrid cells in browsing and editing mode.

- * A renderer refers to a control class that is to be instantiated as a control.

- * For more details, see {@link TRepeater} and {@link TDataList}.

-/**

- * TButton class

- *

- * TButton creates a click button on the page. It is mainly used to submit data to a page.

- *

- * TButton raises two server-side events, {@link onClick OnClick} and {@link onCommand OnCommand},

- * when it is clicked on the client-side. The difference between these two events

- * is that the event {@link onCommand OnCommand} is bubbled up to the button's ancestor controls.

- * And within the event parameter for {@link onCommand OnCommand} contains the reference

- * to the {@link setCommandName CommandName} and {@link setCommandParameter CommandParameter}

- * property values that are set for the button object. This allows you to create multiple TButton

- * components on a Web page and programmatically determine which one is clicked

- * with what parameter.

- *

- * Clicking on button can also trigger form validation, if

- * {@link setCausesValidation CausesValidation} is true.

- * The validation may be restricted within a certain group of validator

- * controls by setting {@link setValidationGroup ValidationGroup} property.

- * If validation is successful, the data will be post back to the same page.

- *

- * TButton displays the {@link setText Text} property as the button caption.

- *

- * TButton can be one of three {@link setButtonType ButtonType}: Submit, Button and Reset.

- * By default, it is a Submit button and the form submission uses the browser's

- * default submission capability. If it is Button or Reset, postback may occur

- * if one of the following conditions is met:

- * - an event handler is attached to {@link onClick OnClick} event;

- * - an event handler is attached to {@link onCommand OnCommand} event;

- * - the button is in a non-empty validation group.

- * In addition, clicking on a Reset button will clear up all input fields

- * if the button does not cause a postback.

- * TButtonColumn class

- *

- * TButtonColumn contains a user-defined command button, such as Add or Remove,

- *

- * The caption of the buttons in the column is determined by {@link setText Text}

- * and {@link setDataTextField DataTextField} properties. If both are present,

- * the latter takes precedence. The {@link setDataTextField DataTextField} property

- * refers to the name of the field in datasource whose value will be used as the button caption.

- * If {@link setDataTextFormatString DataTextFormatString} is not empty,

- * the value will be formatted before rendering.

- *

- * The buttons in the column can be set to display as hyperlinks or push buttons

- * by setting the {@link setButtonType ButtonType} property.

- * The {@link setCommandName CommandName} will assign its value to

- * all button's <b>CommandName</b> property. The datagrid will capture

- * the command event where you can write event handlers based on different command names.

- * The buttons' <b>CausesValidation</b> and <b>ValidationGroup</b> property values

- * are determined by the column's corresponding properties.

- *

- * The buttons in the column can be accessed by one of the following two methods:

- * <code>

- * $datagridItem->ButtonColumnID->Button

- * $datagridItem->ButtonColumnID->Controls[0]

- * </code>

- * The second method is possible because the button control created within the

- * datagrid cell is the first child.

-/**

- * TCaptcha class.

- *

- * Notice: while this class is easy to use and implement, it does not provide full security.

- * In fact, it's easy to bypass the checks reusing old, already-validated tokens (reply attack).

- * A better alternative is provided by {@link TReCaptcha}.

- *

- * TCaptcha displays a CAPTCHA (a token displayed as an image) that can be used

- * to determine if the input is entered by a real user instead of some program.

- *

- * Unlike other CAPTCHA scripts, TCaptcha does not need session or cookie.

- *

- * The token (a string consisting of alphanumeric characters) displayed is automatically

- * generated and can be configured in several ways. To specify the length of characters

- * in the token, set {@link setMinTokenLength MinTokenLength} and {@link setMaxTokenLength MaxTokenLength}.

- * To use case-insensitive comparison and generate upper-case-only token, set {@link setCaseSensitive CaseSensitive}

- * to false. Advanced users can try to set {@link setTokenAlphabet TokenAlphabet}, which

- * specifies what characters can appear in tokens.

- *

- * The validation of the token is related with two properties: {@link setTestLimit TestLimit}

- * and {@link setTokenExpiry TokenExpiry}. The former specifies how many times a token can

- * be tested with on the server side, and the latter says when a generated token will expire.

- *

- * To specify the appearance of the generated token image, set {@link setTokenImageTheme TokenImageTheme}

- * to be an integer between 0 and 63. And to adjust the generated image size, set {@link setTokenFontSize TokenFontSize}

- * (you may also set {@link TWebControl::setWidth Width}, but the scaled image may not look good.)

- * By setting {@link setChangingTokenBackground ChangingTokenBackground} to true, the image background

- * of the token will be variating even though the token is the same during postbacks.

- *

- * Upon postback, user input can be validated by calling {@link validate()}.

- * The {@link TCaptchaValidator} control can also be used to do validation, which provides

- * client-side validation besides the server-side validation.  By default, the token will

- * remain the same during multiple postbacks. A new one can be generated by calling

- * {@link regenerateToken()} manually.

- *

- * The following template shows a typical use of TCaptcha control:

- * <code>

- * <com:TCaptcha ID="Captcha" />

- * <com:TTextBox ID="Input" />

- * <com:TCaptchaValidator CaptchaControl="Captcha"

- *                        ControlToValidate="Input"

- *                        ErrorMessage="You are challenged!" />

- * TColorPicker class.

- *

- * TColorPicker displays a text box for color input purpose.

- * Next to the textbox there's a button filled with the current chosen color.

- * Users can write a color name directly in the text box as an hex triplet (also known as HTML notation, eg: #FF00FF).

- * Alternatively, if the <b>ShowColorPicker</b> property is enabled (it is by default), users can click the button

- * to have a color picker UI appear. A color chan be chosen directly by clicking on the color picker.

- *

- * TColorPicker has three different color picker UI <b>Mode</b>s:

- *  # <b>Simple</b> - Grid with 12 simple colors.

- *  # <b>Basic</b> - Grid with the most common 70 colors. This is the default mode.

- *  # <b>Full</b> - Full-featured color picker.

- * 

- * The <b>CssClass</b> property can be used to override the CSS class name

- * for the color picker panel. The <b>ColorStyle</b> property sets the packages

- * styles available. E.g. <b>default</b>.

- * 

- * If the <b>Mode</b> property is set to <b>Full</b>, the color picker panel will

- * display an "Ok" and "Cancel" buttons. You can customize the button labels setting the <b>OKButtonText</b>

- * and <b>CancelButtonText</b> properties.

- * - <b>Integer</b> A 32-bit signed integer data type.

- * - <b>Float</b> A double-precision floating point number data type.

- * - <b>Date</b> A date data type. The format can be specified by the

- * TConditional class.

- *

- * TConditional displays appropriate content based on the evaluation result

- * of a PHP expression specified via {@link setCondition Condition}.

- * If the result is true, it instantiates the template {@link getTrueTemplate TrueTemplate};

- * otherwise, the template {@link getFalseTemplate FalseTemplate} is instantiated.

- * The PHP expression is evaluated right before {@link onInit} stage of the control lifecycle.

- *

- * Since {@link setCondition Condition} is evaluated at a very early stage, it is recommended

- * you set {@link setCondition Condition} in template and the expression should not refer to

- * objects that are available on or after {@link onInit} lifecycle.

- *

- * A typical usage of TConditional is shown as following:

- * <code>

- * <com:TConditional Condition="$this->User->IsGuest">

- *   <prop:TrueTemplate>

- *     <a href="path/to/login">Login</a>

- *   <prop:FalseTemplate>

- *     <a href="path/to/logout">Logout</a>

- *   </prop:FalseTemplate>

- * </com:TConditional>

- * </code>

- *

- * TConditional is very light. It instantiates either {@link getTrueTemplate TrueTemplate}

- * or {@link getFalseTemplate FalseTemplate}, but never both. And the condition is evaluated only once.

-/**

- * TDataBoundControl class.

- *

- * TDataBoundControl is the based class for controls that need to populate

- * data from data sources. It provides basic properties and methods that allow

- * the derived controls to associate with data sources and retrieve data from them.

- *

- * TBC....

- *

- * TDataBoundControl is equipped with paging capabilities. By setting

- * {@link setAllowPaging AllowPaging} to true, the input data will be paged

- * and only one page of data is actually populated into the data-bound control.

- * This saves a lot of memory when dealing with larget datasets.

- *

- * To specify the number of data items displayed on each page, set

- * the {@link setPageSize PageSize} property, and to specify which

- * page of data to be displayed, set {@link setCurrentPageIndex CurrentPageIndex}.

- *

- * When the size of the original data is too big to be loaded all in the memory,

- * one can enable custom paging. In custom paging, the total number of data items

- * is specified manually via {@link setVirtualItemCount VirtualItemCount},

- * and the data source only needs to contain the current page of data. To enable

- * custom paging, set {@link setAllowCustomPaging AllowCustomPaging} to true.

+/**
+ * TDataBoundControl class.
+ *
+ * TDataBoundControl is the based class for controls that need to populate
+ * data from data sources. It provides basic properties and methods that allow
+ * the derived controls to associate with data sources and retrieve data from them.
+ *
+ * TBC....
+ *
+ * TDataBoundControl is equipped with paging capabilities. By setting
+ * {@link setAllowPaging AllowPaging} to true, the input data will be paged
+ * and only one page of data is actually populated into the data-bound control.
+ * This saves a lot of memory when dealing with larget datasets.
+ *
+ * To specify the number of data items displayed on each page, set
+ * the {@link setPageSize PageSize} property, and to specify which
+ * page of data to be displayed, set {@link setCurrentPageIndex CurrentPageIndex}.
+ *
+ * When the size of the original data is too big to be loaded all in the memory,
+ * one can enable custom paging. In custom paging, the total number of data items
+ * is specified manually via {@link setVirtualItemCount VirtualItemCount},
+ * and the data source only needs to contain the current page of data. To enable
+ * custom paging, set {@link setAllowCustomPaging AllowCustomPaging} to true.

-/**

- * TDataGrid class

- *

- * TDataGrid represents a data bound and updatable grid control.

- *

- * To populate data into the datagrid, sets its {@link setDataSource DataSource}

- * to a tabular data source and call {@link dataBind()}.

- * Each row of data will be represented by an item in the {@link getItems Items}

- * collection of the datagrid.

- *

- * An item can be at one of three states: browsing, selected and edit.

- * The state determines how the item will be displayed. For example, if an item

- * is in edit state, it may be displayed as a table row with input text boxes

- * if the columns are of type {@link TBoundColumn}; and if in browsing state,

- * they are displayed as static text.

- *

- * To change the state of an item, set {@link setEditItemIndex EditItemIndex}

- * or {@link setSelectedItemIndex SelectedItemIndex} property.

- *

- * Each datagrid item has a {@link TDataGridItem::getItemType type}

- * which tells the position and state of the item in the datalist. An item in the header

- * of the repeater is of type Header. A body item may be of either

- * Item, AlternatingItem, SelectedItem or EditItem, depending whether the item

- * index is odd or even, whether it is being selected or edited.

- *

- * A datagrid is specified with a list of columns. Each column specifies how the corresponding

- * table column will be displayed. For example, the header/footer text of that column,

- * the cells in that column, and so on. The following column types are currently

- * provided by the framework,

- * - {@link TBoundColumn}, associated with a specific field in datasource and displays the corresponding data.

- * - {@link TEditCommandColumn}, displaying edit/update/cancel command buttons

- * - {@link TButtonColumn}, displaying generic command buttons that may be bound to specific field in datasource.

- * - {@link TDropDownListColumn}, displaying a dropdown list when the item is in edit state

- * - {@link THyperLinkColumn}, displaying a hyperlink that may be bound to specific field in datasource.

- * - {@link TCheckBoxColumn}, displaying a checkbox that may be bound to specific field in datasource.

- * - {@link TTemplateColumn}, displaying content based on templates.

- *

- * There are three ways to specify columns for a datagrid.

- * <ul>

- *  <li>Automatically generated based on data source.

- *  By setting {@link setAutoGenerateColumns AutoGenerateColumns} to true,

- *  a list of columns will be automatically generated based on the schema of the data source.

- *  Each column corresponds to a column of the data.</li>

- *  <li>Specified in template. For example,

- *    <code>

- *     <com:TDataGrid ...>

- *        <com:TBoundColumn .../>

- *        <com:TEditCommandColumn .../>

- *     </com:TDataGrid>

- *    </code>

- *  </li>

- *  <li>Manually created in code. Columns can be manipulated via

- *  the {@link setColumns Columns} property of the datagrid. For example,

- *  <code>

- *    $column=new TBoundColumn;

- *    $datagrid->Columns[]=$column;

- *  </code>

- *  </li>

- * </ul>

- * Note, automatically generated columns cannot be accessed via

- * the {@link getColumns Columns} property.

- *

- * TDataGrid supports sorting. If the {@link setAllowSorting AllowSorting}

- * is set to true, a column with nonempty {@link setSortExpression SortExpression}

- * will have its header text displayed as a clickable link button.

- * Clicking on the link button will raise {@link onSortCommand OnSortCommand}

- * event. You can respond to this event, sort the data source according

- * to the event parameter, and then invoke {@link databind()} on the datagrid

- * to show to end users the sorted data.

- *

- * TDataGrid supports paging. If the {@link setAllowPaging AllowPaging}

- * is set to true, a pager will be displayed on top and/or bottom of the table.

- * How the pager will be displayed is determined by the {@link getPagerStyle PagerStyle}

- * property. Clicking on a pager button will raise an {@link onPageIndexChanged OnPageIndexChanged}

- * event. You can respond to this event, specify the page to be displayed by

- * setting {@link setCurrentPageIndex CurrentPageIndex}</b> property,

- * and then invoke {@link databind()} on the datagrid to show to end users

- * a new page of data.

- *

- * TDataGrid supports two kinds of paging. The first one is based on the number of data items in

- * datasource. The number of pages {@link getPageCount PageCount} is calculated based

- * the item number and the {@link setPageSize PageSize} property.

- * The datagrid will manage which section of the data source to be displayed

- * based on the {@link setCurrentPageIndex CurrentPageIndex} property.

- * The second approach calculates the page number based on the

- * {@link setVirtualItemCount VirtualItemCount} property and

- * the {@link setPageSize PageSize} property. The datagrid will always

- * display from the beginning of the datasource up to the number of

- * {@link setPageSize PageSize} data items. This approach is especially

- * useful when the datasource may contain too many data items to be managed by

- * the datagrid efficiently.

- *

- * When the datagrid contains a button control that raises an {@link onCommand OnCommand}

- * event, the event will be bubbled up to the datagrid control.

- * If the event's command name is recognizable by the datagrid control,

- * a corresponding item event will be raised. The following item events will be

- * raised upon a specific command:

- * - OnEditCommand, if CommandName=edit

- * - OnCancelCommand, if CommandName=cancel

- * - OnSelectCommand, if CommandName=select

- * - OnDeleteCommand, if CommandName=delete

- * - OnUpdateCommand, if CommandName=update

- * - onPageIndexChanged, if CommandName=page

- * - OnSortCommand, if CommandName=sort

- * Note, an {@link onItemCommand OnItemCommand} event is raised in addition to

- * the above specific command events.

- *

- * TDataGrid also raises an {@link onItemCreated OnItemCreated} event for

- * every newly created datagrid item. You can respond to this event to customize

- * the content or style of the newly created item.

- *

- * Note, the data bound to the datagrid are reset to null after databinding.

- * There are several ways to access the data associated with a datagrid row:

- * - Access the data in {@link onItemDataBound OnItemDataBound} event

- * - Use {@link getDataKeys DataKeys} to obtain the data key associated with

- * the specified datagrid row and use the key to fetch the corresponding data

- * from some persistent storage such as DB.

- * - Save the data in viewstate and get it back during postbacks.

+/**
+ * TDataGrid class
+ *
+ * TDataGrid represents a data bound and updatable grid control.
+ *
+ * To populate data into the datagrid, sets its {@link setDataSource DataSource}
+ * to a tabular data source and call {@link dataBind()}.
+ * Each row of data will be represented by an item in the {@link getItems Items}
+ * collection of the datagrid.
+ *
+ * An item can be at one of three states: browsing, selected and edit.
+ * The state determines how the item will be displayed. For example, if an item
+ * is in edit state, it may be displayed as a table row with input text boxes
+ * if the columns are of type {@link TBoundColumn}; and if in browsing state,
+ * they are displayed as static text.
+ *
+ * To change the state of an item, set {@link setEditItemIndex EditItemIndex}
+ * or {@link setSelectedItemIndex SelectedItemIndex} property.
+ *
+ * Each datagrid item has a {@link TDataGridItem::getItemType type}
+ * which tells the position and state of the item in the datalist. An item in the header
+ * of the repeater is of type Header. A body item may be of either
+ * Item, AlternatingItem, SelectedItem or EditItem, depending whether the item
+ * index is odd or even, whether it is being selected or edited.
+ *
+ * A datagrid is specified with a list of columns. Each column specifies how the corresponding
+ * table column will be displayed. For example, the header/footer text of that column,
+ * the cells in that column, and so on. The following column types are currently
+ * provided by the framework,
+ * - {@link TBoundColumn}, associated with a specific field in datasource and displays the corresponding data.
+ * - {@link TEditCommandColumn}, displaying edit/update/cancel command buttons
+ * - {@link TButtonColumn}, displaying generic command buttons that may be bound to specific field in datasource.
+ * - {@link TDropDownListColumn}, displaying a dropdown list when the item is in edit state
+ * - {@link THyperLinkColumn}, displaying a hyperlink that may be bound to specific field in datasource.
+ * - {@link TCheckBoxColumn}, displaying a checkbox that may be bound to specific field in datasource.
+ * - {@link TTemplateColumn}, displaying content based on templates.
+ *
+ * There are three ways to specify columns for a datagrid.
+ * <ul>
+ *  <li>Automatically generated based on data source.
+ *  By setting {@link setAutoGenerateColumns AutoGenerateColumns} to true,
+ *  a list of columns will be automatically generated based on the schema of the data source.
+ *  Each column corresponds to a column of the data.</li>
+ *  <li>Specified in template. For example,
+ *    <code>
+ *     <com:TDataGrid ...>
+ *        <com:TBoundColumn .../>
+ *        <com:TEditCommandColumn .../>
+ *     </com:TDataGrid>
+ *    </code>
+ *  </li>
+ *  <li>Manually created in code. Columns can be manipulated via
+ *  the {@link setColumns Columns} property of the datagrid. For example,
+ *  <code>
+ *    $column=new TBoundColumn;
+ *    $datagrid->Columns[]=$column;
+ *  </code>
+ *  </li>
+ * </ul>
+ * Note, automatically generated columns cannot be accessed via
+ * the {@link getColumns Columns} property.
+ *
+ * TDataGrid supports sorting. If the {@link setAllowSorting AllowSorting}
+ * is set to true, a column with nonempty {@link setSortExpression SortExpression}
+ * will have its header text displayed as a clickable link button.
+ * Clicking on the link button will raise {@link onSortCommand OnSortCommand}
+ * event. You can respond to this event, sort the data source according
+ * to the event parameter, and then invoke {@link databind()} on the datagrid
+ * to show to end users the sorted data.
+ *
+ * TDataGrid supports paging. If the {@link setAllowPaging AllowPaging}
+ * is set to true, a pager will be displayed on top and/or bottom of the table.
+ * How the pager will be displayed is determined by the {@link getPagerStyle PagerStyle}
+ * property. Clicking on a pager button will raise an {@link onPageIndexChanged OnPageIndexChanged}
+ * event. You can respond to this event, specify the page to be displayed by
+ * setting {@link setCurrentPageIndex CurrentPageIndex}</b> property,
+ * and then invoke {@link databind()} on the datagrid to show to end users
+ * a new page of data.
+ *
+ * TDataGrid supports two kinds of paging. The first one is based on the number of data items in
+ * datasource. The number of pages {@link getPageCount PageCount} is calculated based
+ * the item number and the {@link setPageSize PageSize} property.
+ * The datagrid will manage which section of the data source to be displayed
+ * based on the {@link setCurrentPageIndex CurrentPageIndex} property.
+ * The second approach calculates the page number based on the
+ * {@link setVirtualItemCount VirtualItemCount} property and
+ * the {@link setPageSize PageSize} property. The datagrid will always
+ * display from the beginning of the datasource up to the number of
+ * {@link setPageSize PageSize} data items. This approach is especially
+ * useful when the datasource may contain too many data items to be managed by
+ * the datagrid efficiently.
+ *
+ * When the datagrid contains a button control that raises an {@link onCommand OnCommand}
+ * event, the event will be bubbled up to the datagrid control.
+ * If the event's command name is recognizable by the datagrid control,
+ * a corresponding item event will be raised. The following item events will be
+ * raised upon a specific command:
+ * - OnEditCommand, if CommandName=edit
+ * - OnCancelCommand, if CommandName=cancel
+ * - OnSelectCommand, if CommandName=select
+ * - OnDeleteCommand, if CommandName=delete
+ * - OnUpdateCommand, if CommandName=update
+ * - onPageIndexChanged, if CommandName=page
+ * - OnSortCommand, if CommandName=sort
+ * Note, an {@link onItemCommand OnItemCommand} event is raised in addition to
+ * the above specific command events.
+ *
+ * TDataGrid also raises an {@link onItemCreated OnItemCreated} event for
+ * every newly created datagrid item. You can respond to this event to customize
+ * the content or style of the newly created item.
+ *
+ * Note, the data bound to the datagrid are reset to null after databinding.
+ * There are several ways to access the data associated with a datagrid row:
+ * - Access the data in {@link onItemDataBound OnItemDataBound} event
+ * - Use {@link getDataKeys DataKeys} to obtain the data key associated with
+ * the specified datagrid row and use the key to fetch the corresponding data
+ * from some persistent storage such as DB.
+ * - Save the data in viewstate and get it back during postbacks.

-/**

- * TDataGridColumn class

- *

- * TDataGridColumn serves as the base class for the different column types of

- * the {@link TDataGrid} control.

- * TDataGridColumn defines the properties and methods that are common among

- * all datagrid column types. In particular, it initializes header and footer

- * cells according to {@link setHeaderText HeaderText} and {@link getHeaderStyle HeaderStyle}

- * {@link setFooterText FooterText} and {@link getFooterStyle FooterStyle} properties.

- * If {@link setHeaderImageUrl HeaderImageUrl} is specified, the image

- * will be displayed instead in the header cell.

- * The {@link getItemStyle ItemStyle} is applied to cells that belong to

- * non-header and -footer datagrid items.

- *

- * When the datagrid enables sorting, if the {@link setSortExpression SortExpression}

- * is not empty, the header cell will display a button (linkbutton or imagebutton)

- * that will bubble the sort command event to the datagrid.

- *

- * Since v3.1.0, TDataGridColumn has introduced two new properties {@link setHeaderRenderer HeaderRenderer}

- * and {@link setFooterRenderer FooterRenderer} which can be used to specify

- * the layout of header and footer column cells.

- * A renderer refers to a control class that is to be instantiated as a control.

- * For more details, see {@link TRepeater} and {@link TDataList}.

- *

- * Since v3.1.1, TDataGridColumn has introduced {@link setEnableCellGrouping EnableCellGrouping}.

- * If a column has this property set true, consecutive cells having the same content in this

- * column will be grouped into one cell.

- * Note, there are some limitations to cell grouping. We determine the cell content according to

- * the cell's {@link TTableCell::getText Text} property. If the text is empty and the cell has

- * some child controls, we will pick up the first control who implements {@link IDataRenderer}

- * and obtain its {@link IDataRenderer::getData Data} property.

- *

- * The following datagrid column types are provided by the framework currently,

- * - {@link TBoundColumn}, associated with a specific field in datasource and displays the corresponding data.

- * - {@link TEditCommandColumn}, displaying edit/update/cancel command buttons

- * - {@link TDropDownListColumn}, displaying a dropdown list when the item is in edit state

- * - {@link TButtonColumn}, displaying generic command buttons that may be bound to specific field in datasource.

- * - {@link THyperLinkColumn}, displaying a hyperlink that may be bound to specific field in datasource.

- * - {@link TCheckBoxColumn}, displaying a checkbox that may be bound to specific field in datasource.

- * - {@link TTemplateColumn}, displaying content based on templates.

- *

- * To create your own column class, simply override {@link initializeCell()} method,

- * which is the major logic for managing the data and presentation of cells in the column.

+/**
+ * TDataGridColumn class
+ *
+ * TDataGridColumn serves as the base class for the different column types of
+ * the {@link TDataGrid} control.
+ * TDataGridColumn defines the properties and methods that are common among
+ * all datagrid column types. In particular, it initializes header and footer
+ * cells according to {@link setHeaderText HeaderText} and {@link getHeaderStyle HeaderStyle}
+ * {@link setFooterText FooterText} and {@link getFooterStyle FooterStyle} properties.
+ * If {@link setHeaderImageUrl HeaderImageUrl} is specified, the image
+ * will be displayed instead in the header cell.
+ * The {@link getItemStyle ItemStyle} is applied to cells that belong to
+ * non-header and -footer datagrid items.
+ *
+ * When the datagrid enables sorting, if the {@link setSortExpression SortExpression}
+ * is not empty, the header cell will display a button (linkbutton or imagebutton)
+ * that will bubble the sort command event to the datagrid.
+ *
+ * Since v3.1.0, TDataGridColumn has introduced two new properties {@link setHeaderRenderer HeaderRenderer}
+ * and {@link setFooterRenderer FooterRenderer} which can be used to specify
+ * the layout of header and footer column cells.
+ * A renderer refers to a control class that is to be instantiated as a control.
+ * For more details, see {@link TRepeater} and {@link TDataList}.
+ *
+ * Since v3.1.1, TDataGridColumn has introduced {@link setEnableCellGrouping EnableCellGrouping}.
+ * If a column has this property set true, consecutive cells having the same content in this
+ * column will be grouped into one cell.
+ * Note, there are some limitations to cell grouping. We determine the cell content according to
+ * the cell's {@link TTableCell::getText Text} property. If the text is empty and the cell has
+ * some child controls, we will pick up the first control who implements {@link IDataRenderer}
+ * and obtain its {@link IDataRenderer::getData Data} property.
+ *
+ * The following datagrid column types are provided by the framework currently,
+ * - {@link TBoundColumn}, associated with a specific field in datasource and displays the corresponding data.
+ * - {@link TEditCommandColumn}, displaying edit/update/cancel command buttons
+ * - {@link TDropDownListColumn}, displaying a dropdown list when the item is in edit state
+ * - {@link TButtonColumn}, displaying generic command buttons that may be bound to specific field in datasource.
+ * - {@link THyperLinkColumn}, displaying a hyperlink that may be bound to specific field in datasource.
+ * - {@link TCheckBoxColumn}, displaying a checkbox that may be bound to specific field in datasource.
+ * - {@link TTemplateColumn}, displaying content based on templates.
+ *
+ * To create your own column class, simply override {@link initializeCell()} method,
+ * which is the major logic for managing the data and presentation of cells in the column.

-/**

- * TDataList class

- *

- * TDataList represents a data bound and updatable list control.

- *

- * Like {@link TRepeater}, TDataList displays its content repeatedly based on

- * the data fetched from {@link setDataSource DataSource}.

- * The repeated contents in TDataList are called items, which are controls and

- * can be accessed through {@link getItems Items}. When {@link dataBind()} is

- * invoked, TDataList creates an item for each row of data and binds the data

- * row to the item. Optionally, a TDataList can have a header, a footer and/or

- * separators between items.

- *

- * TDataList differs from {@link TRepeater} in that it supports tiling the items

- * in different manners and it maintains status of items to handle data update.

- *

- * The layout of the repeated contents are specified by inline templates.

- * TDataList items, header, footer, etc. are being instantiated with the corresponding

- * templates when data is being bound to the repeater.

- *

- * Since v3.1.0, the layout can also be by renderers. A renderer is a control class

- * that can be instantiated as datalist items, header, etc. A renderer can thus be viewed

- * as an external template (in fact, it can also be non-templated controls).

- *

- * A renderer can be any control class.

- * - If the class implements {@link IDataRenderer}, the <b>Data</b>

- * property will be set as the data row during databinding. Many PRADO controls

- * implement this interface, such as {@link TLabel}, {@link TTextBox}, etc.

- * - If the class implements {@link IItemDataRenderer}, the <b>ItemIndex</b> property will be set

- * as the zero-based index of the item in the datalist item collection, and

- * the <b>ItemType</b> property as the item's type (such as TListItemType::Item).

- * {@link TDataListItemRenderer} may be used as the convenient base class which

- * already implements {@link IDataItemRenderer}.

- *

- * The following properties are used to specify different types of template and renderer

- * for a datalist:

- * - {@link setItemTemplate ItemTemplate}, {@link setItemRenderer ItemRenderer}:

- * for each repeated row of data

- * - {@link setAlternatingItemTemplate AlternatingItemTemplate}, {@link setAlternatingItemRenderer AlternatingItemRenderer}:

- * for each alternating row of data. If not set, {@link setItemTemplate ItemTemplate} or {@link setItemRenderer ItemRenderer}

- * will be used instead.

- * - {@link setHeaderTemplate HeaderTemplate}, {@link setHeaderRenderer HeaderRenderer}:

- * for the datalist header.

- * - {@link setFooterTemplate FooterTemplate}, {@link setFooterRenderer FooterRenderer}:

- * for the datalist footer.

- * - {@link setSeparatorTemplate SeparatorTemplate}, {@link setSeparatorRenderer SeparatorRenderer}:

- * for content to be displayed between items.

- * - {@link setEmptyTemplate EmptyTemplate}, {@link setEmptyRenderer EmptyRenderer}:

- * used when data bound to the datalist is empty.

- * - {@link setEditItemTemplate EditItemTemplate}, {@link setEditItemRenderer EditItemRenderer}:

- * for the row being editted.

- * - {@link setSelectedItemTemplate SelectedItemTemplate}, {@link setSelectedItemRenderer SelectedItemRenderer}:

- * for the row being selected.

- *

- * If a content type is defined with both a template and a renderer, the latter takes precedence.

- *

- * When {@link dataBind()} is being called, TDataList undergoes the following lifecycles for each row of data:

- * - create item based on templates or renderers

- * - set the row of data to the item

- * - raise {@link onItemCreated OnItemCreated}:

- * - add the item as a child control

- * - call dataBind() of the item

- * - raise {@link onItemDataBound OnItemDataBound}:

- *

- * TDataList raises an {@link onItemCommand OnItemCommand} whenever a button control

- * within some datalist item raises a <b>OnCommand</b> event. Therefore,

- * you can handle all sorts of <b>OnCommand</b> event in a central place by

- * writing an event handler for {@link onItemCommand OnItemCommand}.

- *

- * An additional event is raised if the <b>OnCommand</b> event has one of the following

- * command names:

- * - edit: user wants to edit an item. <b>OnEditCommand</b> event will be raised.

- * - update: user wants to save the change to an item. <b>OnUpdateCommand</b> event will be raised.

- * - select: user selects an item. <b>OnSelectedIndexChanged</b> event will be raised.

- * - delete: user deletes an item. <b>OnDeleteCommand</b> event will be raised.

- * - cancel: user cancels previously editting action. <b>OnCancelCommand</b> event will be raised.

- *

- * TDataList provides a few properties to support tiling the items.

- * The number of columns used to display the data items is specified via

- * {@link setRepeatColumns RepeatColumns} property, while the {@link setRepeatDirection RepeatDirection}

- * governs the order of the items being rendered.

- * The layout of the data items in the list is specified via {@link setRepeatLayout RepeatLayout},

- * which can take one of the following values:

- * - Table (default): items are organized using HTML table and cells.

- * When using this layout, one can set {@link setCellPadding CellPadding} and

- * {@link setCellSpacing CellSpacing} to adjust the cellpadding and cellpadding

- * of the table, and {@link setCaption Caption} and {@link setCaptionAlign CaptionAlign}

- * to add a table caption with the specified alignment.

- * - Flow: items are organized using HTML spans and breaks.

- * - Raw: TDataList does not generate any HTML tags to do the tiling.

- *

- * Items in TDataList can be in one of the three status: normal browsing,

- * being editted and being selected. To change the status of a particular

- * item, set {@link setSelectedItemIndex SelectedItemIndex} or

- * {@link setEditItemIndex EditItemIndex}. The former will change

- * the indicated item to selected mode, which will cause the item to

- * use {@link setSelectedItemTemplate SelectedItemTemplate} or

- * {@link setSelectedItemRenderer SelectedItemRenderer} for presentation.

- * The latter will change the indicated item to edit mode and to use corresponding

- * template or renderer.

- * Note, if an item is in edit mode, then selecting this item will have no effect.

- *

- * Different styles may be applied to items in different status. The style

- * application is performed in a hierarchical way: Style in higher hierarchy

- * will inherit from styles in lower hierarchy.

- * Starting from the lowest hierarchy, the item styles include

- * - item's own style

- * - {@link getItemStyle ItemStyle}

- * - {@link getAlternatingItemStyle AlternatingItemStyle}

- * - {@link getSelectedItemStyle SelectedItemStyle}

- * - {@link getEditItemStyle EditItemStyle}.

- * Therefore, if background color is set as red in {@link getItemStyle ItemStyle},

- * {@link getEditItemStyle EditItemStyle} will also have red background color

- * unless it is set to a different value explicitly.

- *

- * When a page containing a datalist is post back, the datalist will restore automatically

- * all its contents, including items, header, footer and separators.

- * However, the data row associated with each item will not be recovered and become null.

- * To access the data, use one of the following ways:

- * - Use {@link getDataKeys DataKeys} to obtain the data key associated with

- * the specified datalist item and use the key to fetch the corresponding data

- * from some persistent storage such as DB.

- * - Save the whole dataset in viewstate, which will restore the dataset automatically upon postback.

- * Be aware though, if the size of your dataset is big, your page size will become big. Some

- * complex data may also have serializing problem if saved in viewstate.

+ * templates when data is being bound to the repeater.
+ *
+ * Since v3.1.0, the layout can also be by renderers. A renderer is a control class
+ * that can be instantiated as datalist items, header, etc. A renderer can thus be viewed
+ * as an external template (in fact, it can also be non-templated controls).
+ *
+ * A renderer can be any control class.
+ * - If the class implements {@link IDataRenderer}, the <b>Data</b>
+ * property will be set as the data row during databinding. Many PRADO controls
+ * implement this interface, such as {@link TLabel}, {@link TTextBox}, etc.
+ * - If the class implements {@link IItemDataRenderer}, the <b>ItemIndex</b> property will be set
+ * as the zero-based index of the item in the datalist item collection, and
+ * the <b>ItemType</b> property as the item's type (such as TListItemType::Item).
+ * {@link TDataListItemRenderer} may be used as the convenient base class which
+ * already implements {@link IDataItemRenderer}.
+ *
+ * The following properties are used to specify different types of template and renderer
+ * for a datalist:
+ * - {@link setItemTemplate ItemTemplate}, {@link setItemRenderer ItemRenderer}:
+ * for each repeated row of data
+ * - {@link setAlternatingItemTemplate AlternatingItemTemplate}, {@link setAlternatingItemRenderer AlternatingItemRenderer}:
+ * for each alternating row of data. If not set, {@link setItemTemplate ItemTemplate} or {@link setItemRenderer ItemRenderer}
+ * will be used instead.
+ * - {@link setHeaderTemplate HeaderTemplate}, {@link setHeaderRenderer HeaderRenderer}:
+ * for the datalist header.
+ * - {@link setFooterTemplate FooterTemplate}, {@link setFooterRenderer FooterRenderer}:
+ * for the datalist footer.
+ * - {@link setSeparatorTemplate SeparatorTemplate}, {@link setSeparatorRenderer SeparatorRenderer}:
+ * for content to be displayed between items.
+ * - {@link setEmptyTemplate EmptyTemplate}, {@link setEmptyRenderer EmptyRenderer}:
+ * used when data bound to the datalist is empty.
+ * - {@link setEditItemTemplate EditItemTemplate}, {@link setEditItemRenderer EditItemRenderer}:
+ * for the row being editted.
+ * - {@link setSelectedItemTemplate SelectedItemTemplate}, {@link setSelectedItemRenderer SelectedItemRenderer}:
+ * for the row being selected.
+ *
+ * If a content type is defined with both a template and a renderer, the latter takes precedence.
+ *
+ * When {@link dataBind()} is being called, TDataList undergoes the following lifecycles for each row of data:
+ * - create item based on templates or renderers
+ * - set the row of data to the item
+ * - raise {@link onItemCreated OnItemCreated}:
+ * - add the item as a child control
+ * - call dataBind() of the item
+ * - raise {@link onItemDataBound OnItemDataBound}:
+ *
+ * TDataList raises an {@link onItemCommand OnItemCommand} whenever a button control
+ * within some datalist item raises a <b>OnCommand</b> event. Therefore,
+ * you can handle all sorts of <b>OnCommand</b> event in a central place by
+ * writing an event handler for {@link onItemCommand OnItemCommand}.
+ *
+ * An additional event is raised if the <b>OnCommand</b> event has one of the following
+ * command names:
+ * - edit: user wants to edit an item. <b>OnEditCommand</b> event will be raised.
+ * - update: user wants to save the change to an item. <b>OnUpdateCommand</b> event will be raised.
+ * - select: user selects an item. <b>OnSelectedIndexChanged</b> event will be raised.
+ * - delete: user deletes an item. <b>OnDeleteCommand</b> event will be raised.
+ * - cancel: user cancels previously editting action. <b>OnCancelCommand</b> event will be raised.
+ *
+ * TDataList provides a few properties to support tiling the items.
+ * The number of columns used to display the data items is specified via
+ * {@link setRepeatColumns RepeatColumns} property, while the {@link setRepeatDirection RepeatDirection}
+ * governs the order of the items being rendered.
+ * The layout of the data items in the list is specified via {@link setRepeatLayout RepeatLayout},
+ * which can take one of the following values:
+ * - Table (default): items are organized using HTML table and cells.
+ * When using this layout, one can set {@link setCellPadding CellPadding} and
+ * {@link setCellSpacing CellSpacing} to adjust the cellpadding and cellpadding
+ * of the table, and {@link setCaption Caption} and {@link setCaptionAlign CaptionAlign}
+ * to add a table caption with the specified alignment.
+ * - Flow: items are organized using HTML spans and breaks.
+ * - Raw: TDataList does not generate any HTML tags to do the tiling.
+ *
+ * Items in TDataList can be in one of the three status: normal browsing,
+ * being editted and being selected. To change the status of a particular
+ * item, set {@link setSelectedItemIndex SelectedItemIndex} or
+ * {@link setEditItemIndex EditItemIndex}. The former will change
+ * the indicated item to selected mode, which will cause the item to
+ * use {@link setSelectedItemTemplate SelectedItemTemplate} or
+ * {@link setSelectedItemRenderer SelectedItemRenderer} for presentation.
+ * The latter will change the indicated item to edit mode and to use corresponding
+ * template or renderer.
+ * Note, if an item is in edit mode, then selecting this item will have no effect.
+ *
+ * Different styles may be applied to items in different status. The style
+ * application is performed in a hierarchical way: Style in higher hierarchy
+ * will inherit from styles in lower hierarchy.
+ * Starting from the lowest hierarchy, the item styles include
+ * - item's own style
+ * - {@link getItemStyle ItemStyle}
+ * - {@link getAlternatingItemStyle AlternatingItemStyle}
+ * - {@link getSelectedItemStyle SelectedItemStyle}
+ * - {@link getEditItemStyle EditItemStyle}.
+ * Therefore, if background color is set as red in {@link getItemStyle ItemStyle},
+ * {@link getEditItemStyle EditItemStyle} will also have red background color
+ * unless it is set to a different value explicitly.
+ *
+ * When a page containing a datalist is post back, the datalist will restore automatically
+ * all its contents, including items, header, footer and separators.
+ * However, the data row associated with each item will not be recovered and become null.
+ * To access the data, use one of the following ways:
+ * - Use {@link getDataKeys DataKeys} to obtain the data key associated with
+ * the specified datalist item and use the key to fetch the corresponding data
+ * from some persistent storage such as DB.
+ * - Save the whole dataset in viewstate, which will restore the dataset automatically upon postback.
+ * Be aware though, if the size of your dataset is big, your page size will become big. Some
+ * complex data may also have serializing problem if saved in viewstate.

-/**

- *

- * TDatePicker class.

- *

- * TDatePicker displays a text box for date input purpose.

- * When the text box receives focus, a calendar will pop up and users can

- * pick up from it a date that will be automatically entered into the text box.

- * The format of the date string displayed in the text box is determined by

- * the <b>DateFormat</b> property. Valid formats are the combination of the

- * following tokens,

- *

- * <code>

- *  Character Format Pattern (en-US)

- *  -----------------------------------------

- *  d          day digit

- *  dd         padded day digit e.g. 01, 02

- *  M          month digit

- *  MM         padded month digit

- *  MMMM       localized month name, e.g. March, April

- *  yy         2 digit year

- *  yyyy       4 digit year

- *  -----------------------------------------

- * </code>

- *

- * TDatePicker has four <b>Mode</b> to show the date picker popup.

- *

- *  # <b>Basic</b> -- Only shows a text input, focusing on the input shows the

- *                    date picker. This way you can access the popup using only

- *                    the keyboard. Note that because of this, TAB-bing through

- *                    this control will automatically select the current date if

- *                    no previous date was selected. If you close the popup (eg.

- *                    pressing the ESC key) you'll need to un-focus and re-focus

- *                    the control again for the popup to reappear.

- *  # <b>Clickable</b> -- Only shows a text input, clicking on the input shows the

- *                    date picker. This mode solves the two small problems of the

- *                    Basic mode. It was first introduced in Prado 3.2.

- *  # <b>Button</b> -- Shows a button next to the text input, clicking on the

- *                     button shows the date, button text can be by the

- *                     <b>ButtonText</b> property

- *  # <b>ImageButton</b> -- Shows an image next to the text input, clicking on

- *                          the image shows the date picker, image source can be

- *                          change through the <b>ButtonImageUrl</b> property.

- *

- * The <b>CssClass</b> property can be used to override the css class name

- * for the date picker panel. <b>CalendarStyle</b> property sets the packages

- * styles available. E.g. <b>default</b>.

- *

- * The <b>InputMode</b> property can be set to "TextBox" or "DropDownList" with

- * default as "TextBox".

- * In <b>DropDownList</b> mode, in addition to the popup date picker, three

- * drop down list (day, month and year) are presented to select the date .

- *

- * The <b>PositionMode</b> property can be set to "Top" or "Bottom" with default

- * as "Bottom". It specifies the position of the calendar popup, relative to the

- * input field.

+ *
+ * TDatePicker class.
+ *
+ * TDatePicker displays a text box for date input purpose.
+ * When the text box receives focus, a calendar will pop up and users can
+ * pick up from it a date that will be automatically entered into the text box.
+ * The format of the date string displayed in the text box is determined by
+ * the <b>DateFormat</b> property. Valid formats are the combination of the
+ * following tokens,
+ *
+ * <code>
+ *  Character Format Pattern (en-US)
+ *  -----------------------------------------
+ *  d          day digit
+ *  dd         padded day digit e.g. 01, 02
+ *  M          month digit
+ *  MM         padded month digit
+ *  MMMM       localized month name, e.g. March, April
+ *  yy         2 digit year
+ *  yyyy       4 digit year
+ *  -----------------------------------------
+ * </code>
+ *
+ * TDatePicker has four <b>Mode</b> to show the date picker popup.
+ *
+ *  # <b>Basic</b> -- Only shows a text input, focusing on the input shows the
+ *                    date picker. This way you can access the popup using only
+ *                    the keyboard. Note that because of this, TAB-bing through
+ *                    this control will automatically select the current date if
+ *                    no previous date was selected. If you close the popup (eg.
+ *                    pressing the ESC key) you'll need to un-focus and re-focus
+ *                    the control again for the popup to reappear.
+ *  # <b>Clickable</b> -- Only shows a text input, clicking on the input shows the
+ *                    date picker. This mode solves the two small problems of the
+ *                    Basic mode. It was first introduced in Prado 3.2.
+ *  # <b>Button</b> -- Shows a button next to the text input, clicking on the
+ *                     button shows the date, button text can be by the
+ *                     <b>ButtonText</b> property
+ *  # <b>ImageButton</b> -- Shows an image next to the text input, clicking on
+ *                          the image shows the date picker, image source can be
+ *                          change through the <b>ButtonImageUrl</b> property.
+ *
+ * The <b>CssClass</b> property can be used to override the css class name
+ * for the date picker panel. <b>CalendarStyle</b> property sets the packages
+ * styles available. E.g. <b>default</b>.
+ *
+ * The <b>InputMode</b> property can be set to "TextBox" or "DropDownList" with
+ * default as "TextBox".
+ * In <b>DropDownList</b> mode, in addition to the popup date picker, three
+ * drop down list (day, month and year) are presented to select the date .
+ *
+ * The <b>PositionMode</b> property can be set to "Top" or "Bottom" with default
+ * as "Bottom". It specifies the position of the calendar popup, relative to the
+ * input field.

-/**

- * TDropDownListColumn class

- *

- * TDropDownListColumn represents a column that is bound to a field in a data source.

- * The cells in the column will be displayed using the data indexed by

- * {@link setDataTextField DataTextField}. You can customize the display by

- * setting {@link setDataTextFormatString DataTextFormatString}.

- *

- * If {@link setReadOnly ReadOnly} is false, TDropDownListColumn will display cells in edit mode

- * with dropdown lists. Otherwise, a static text is displayed.

- * The currently selected dropndown list item is specified by the data indexed with

- * {@link setDataValueField DataValueField}.

- *

- * There are two approaches to specify the list items available for selection.

- * The first approach uses template syntax as follows,

- * <code>

- *   <com:TDropDownListColumn ....>

- *     <com:TListItem Value="1" Text="first item" />

- *     <com:TListItem Value="2" Text="second item" />

- *     <com:TListItem Value="3" Text="third item" />

- *   </com:TDropDownListColumn>

- * </code>

- * The second approach specifies a data source to be bound to the dropdown lists

- * by setting {@link setListDataSource ListDataSource}. Like generic list controls,

- * you may also want to specify which data fields are used for item values and texts

- * by setting {@link setListValueField ListValueField} and

- * {@link setListTextField ListTextField}, respectively.

- * Furthermore, the item texts may be formatted by using {@link setListTextFormatString ListTextFormatString}.

- * Note, if you specify {@link setListDataSource ListDataSource}, do it before

- * calling the datagrid's dataBind().

- *

- * The dropdown list control in the TDropDownListColumn can be accessed by one of

- * the following two methods:

- * <code>

- * $datagridItem->DropDownListColumnID->DropDownList

- * $datagridItem->DropDownListColumnID->Controls[0]

- * </code>

- * The second method is possible because the dropdown list control created within the

- * datagrid cell is the first child.

+ * TDropDownListColumn class
+ *
+ * TDropDownListColumn represents a column that is bound to a field in a data source.
+ * The cells in the column will be displayed using the data indexed by
+ * {@link setDataTextField DataTextField}. You can customize the display by
+ * setting {@link setDataTextFormatString DataTextFormatString}.
+ *
+ * If {@link setReadOnly ReadOnly} is false, TDropDownListColumn will display cells in edit mode
+ * with dropdown lists. Otherwise, a static text is displayed.
+ * The currently selected dropndown list item is specified by the data indexed with
+ * {@link setDataValueField DataValueField}.
+ *
+ * There are two approaches to specify the list items available for selection.
+ * The first approach uses template syntax as follows,
+ * <code>
+ *   <com:TDropDownListColumn ....>
+ *     <com:TListItem Value="1" Text="first item" />
+ *     <com:TListItem Value="2" Text="second item" />
+ *     <com:TListItem Value="3" Text="third item" />
+ *   </com:TDropDownListColumn>
+ * </code>
+ * The second approach specifies a data source to be bound to the dropdown lists
+ * by setting {@link setListDataSource ListDataSource}. Like generic list controls,
+ * you may also want to specify which data fields are used for item values and texts
+ * by setting {@link setListValueField ListValueField} and
+ * {@link setListTextField ListTextField}, respectively.
+ * Furthermore, the item texts may be formatted by using {@link setListTextFormatString ListTextFormatString}.
+ * Note, if you specify {@link setListDataSource ListDataSource}, do it before
+ * calling the datagrid's dataBind().
+ *
+ * The dropdown list control in the TDropDownListColumn can be accessed by one of
+ * the following two methods:
+ * <code>
+ * $datagridItem->DropDownListColumnID->DropDownList
+ * $datagridItem->DropDownListColumnID->Controls[0]
+ * </code>
+ * The second method is possible because the dropdown list control created within the
+ * datagrid cell is the first child.

- * THead class

- *

- * THead displays a head element on a page. It displays the content

- * enclosed in its body and the page title set by the

- * {@link setTitle Title} property. In addition, stylesheets and JavaScripts registered via

- * {@link TClientScriptManager::registerStyleSheet}, {@link TClientScriptManager::registerStyleSheetFile}

- * {@link TClientScriptManager::registerHeadJavaScript}, and

- * {@link TClientScriptManager::registerHeadJavaScriptFile} will also be displayed

- * in the head.

- * THead also manages and displays meta tags through its {@link getMetaTags MetaTags}

- * property. You can add a meta object to the collection in code dynamically,

- * or add it in template using the following syntax,

- * <code>

- * <com:THead>

- *   <com:TMetaTag HttpEquiv="Pragma" Content="no-cache" />

- *   <com:TMetaTag Name="keywords" Content="Prado" />

- * </com:THead>

- * </code>

- *

- * Note, {@link TPage} has a property {@link TPage::getHead Head} that refers to

- * the THead control currently on the page. A page can have at most one THead

- * control. Although not required, it is recommended to place a THead on your page.

- * Without a THead on the page, stylesheets and javascripts in the current page

- * theme will not be rendered.

- * THyperLinkColumn class

- *

- * THyperLinkColumn contains a hyperlink for each item in the column.

- * You can set the text and the url of the hyperlink by {@link setText Text}

- * and {@link setNavigateUrl NavigateUrl} properties, respectively.

- * You can also bind the text and url to specific data field in datasource

- * by setting {@link setDataTextField DataTextField} and

- * {@link setDataNavigateUrlField DataNavigateUrlField}.

- * Both can be formatted before rendering according to the

- * {@link setDataTextFormatString DataTextFormatString} and

- * and {@link setDataNavigateUrlFormatString DataNavigateUrlFormatString}

- * properties, respectively. If both {@link setText Text} and {@link setDataTextField DataTextField}

- * are present, the latter takes precedence.

- * The same rule applies to {@link setNavigateUrl NavigateUrl} and

- * {@link setDataNavigateUrlField DataNavigateUrlField} properties.

- *

- * The hyperlinks in the column can be accessed by one of the following two methods:

- * <code>

- * $datagridItem->HyperLinkColumnID->HyperLink

- * $datagridItem->HyperLinkColumnID->Controls[0]

- * </code>

- * The second method is possible because the hyperlink control created within the

- * datagrid cell is the first child.

-/**

- * TImageButton class

- *

- * TImageButton creates an image button on the page. It is used to submit data to a page.

- * You can create either a <b>submit</b> button or a <b>command</b> button.

- *

- * A <b>command</b> button has a command name (specified by

- * the {@link setCommandName CommandName} property) and and a command parameter

- * (specified by {@link setCommandParameter CommandParameter} property)

- * associated with the button. This allows you to create multiple TLinkButton

- * components on a Web page and programmatically determine which one is clicked

- * with what parameter. You can provide an event handler for

- * {@link onCommand OnCommand} event to programmatically control the actions performed

- * when the command button is clicked. In the event handler, you can determine

- * the {@link setCommandName CommandName} property value and

- * the {@link setCommandParameter CommandParameter} property value

- * through the {@link TCommandParameter::getName Name} and

- * {@link TCommandParameter::getParameter Parameter} properties of the event

- * parameter which is of type {@link TCommandEventParameter}.

- *

- * A <b>submit</b> button does not have a command name associated with the button

- * and clicking on it simply posts the Web page back to the server.

- * By default, a TImageButton control is a submit button.

- * You can provide an event handler for the {@link onClick OnClick} event

- * to programmatically control the actions performed when the submit button is clicked.

- * The coordinates of the clicking point can be obtained from the {@link onClick OnClick}

- * event parameter, which is of type {@link TImageClickEventParameter}.

- *

- * Clicking on button can trigger form validation, if

- * {@link setCausesValidation CausesValidation} is true.

- * And the validation may be restricted within a certain group of validator

- * controls by setting {@link setValidationGroup ValidationGroup} property.

- * If validation is successful, the data will be post back to the same page.

- *

- * TImageButton displays the {@link setText Text} property as the hint text to the displayed image.

+ * TImageButton class
+ *
+ * TImageButton creates an image button on the page. It is used to submit data to a page.
+ * You can create either a <b>submit</b> button or a <b>command</b> button.
+ *
+ * A <b>command</b> button has a command name (specified by
+ * the {@link setCommandName CommandName} property) and and a command parameter
+ * (specified by {@link setCommandParameter CommandParameter} property)
+ * associated with the button. This allows you to create multiple TLinkButton
+ * components on a Web page and programmatically determine which one is clicked
+ * with what parameter. You can provide an event handler for
+ * {@link onCommand OnCommand} event to programmatically control the actions performed
+ * when the command button is clicked. In the event handler, you can determine
+ * the {@link setCommandName CommandName} property value and
+ * the {@link setCommandParameter CommandParameter} property value
+ * through the {@link TCommandParameter::getName Name} and
+ * {@link TCommandParameter::getParameter Parameter} properties of the event
+ * parameter which is of type {@link TCommandEventParameter}.
+ *
+ * A <b>submit</b> button does not have a command name associated with the button
+ * and clicking on it simply posts the Web page back to the server.
+ * By default, a TImageButton control is a submit button.
+ * You can provide an event handler for the {@link onClick OnClick} event
+ * to programmatically control the actions performed when the submit button is clicked.
+ * The coordinates of the clicking point can be obtained from the {@link onClick OnClick}
+ * event parameter, which is of type {@link TImageClickEventParameter}.
+ *
+ * Clicking on button can trigger form validation, if
+ * {@link setCausesValidation CausesValidation} is true.
+ * And the validation may be restricted within a certain group of validator
+ * controls by setting {@link setValidationGroup ValidationGroup} property.
+ * If validation is successful, the data will be post back to the same page.
+ *
+ * TImageButton displays the {@link setText Text} property as the hint text to the displayed image.

- * TImageMap represents an image on a page. Hotspot regions can be defined

- * within the image. Depending on the {@link setHotSpotMode HotSpotMode},

- * clicking on the hotspots may trigger a postback or navigate to a specified

- * URL. The hotspots defined may be accessed via {@link getHotSpots HotSpots}.

- * Each hotspot is described as a {@link THotSpot}, which can be a circle,

- * rectangle, polygon, etc. To add hotspot in a template, use the following,

- * <code>

- *  <com:TImageMap>

- *    <com:TCircleHotSpot ... />

- *    <com:TRectangleHotSpot ... />

- *    <com:TPolygonHotSpot ... />

-/**

- * TLinkButton class

- *

- * TLinkButton creates a hyperlink style button on the page.

- * TLinkButton has the same appearance as a hyperlink. However, it is mainly

- * used to submit data to a page. Like {@link TButton}, you can create either

- * a <b>submit</b> button or a <b>command</b> button.

- *

- * A <b>command</b> button has a command name (specified by

- * the {@link setCommandName CommandName} property) and and a command parameter

- * (specified by {@link setCommandParameter CommandParameter} property)

- * associated with the button. This allows you to create multiple TLinkButton

- * components on a Web page and programmatically determine which one is clicked

- * with what parameter. You can provide an event handler for

- * {@link onCommand OnCommand} event to programmatically control the actions performed

- * when the command button is clicked. In the event handler, you can determine

- * the {@link setCommandName CommandName} property value and

- * the {@link setCommandParameter CommandParameter} property value

- * through the {@link TCommandParameter::getName Name} and

- * {@link TCommandParameter::getParameter Parameter} properties of the event

- * parameter which is of type {@link TCommandEventParameter}.

- *

- * A <b>submit</b> button does not have a command name associated with the button

- * and clicking on it simply posts the Web page back to the server.

- * By default, a TLinkButton component is a submit button.

- * You can provide an event handler for the {@link onClick OnClick} event

- * to programmatically control the actions performed when the submit button is clicked.

- *

- * Clicking on button can trigger form validation, if

- * {@link setCausesValidation CausesValidation} is true.

- * And the validation may be restricted within a certain group of validator

- * controls by setting {@link setValidationGroup ValidationGroup} property.

- * If validation is successful, the data will be post back to the same page.

- *

- * TLinkButton will display the {@link setText Text} property value

- * as the hyperlink text. If {@link setText Text} is empty, the body content

- * of TLinkButton will be displayed. Therefore, you can use TLinkButton

- * as an image button by enclosing an &lt;img&gt; tag as the body of TLinkButton.

- * The property {@link getItems} returns a list of the items in the control.

- * To specify or determine which item is selected, use the

- * {@link getSelectedIndex SelectedIndex} property that indicates the zero-based

- * index of the selected item in the item list. You may also use

- * {@link getSelectedItem SelectedItem} and {@link getSelectedValue SelectedValue}

- * to get the selected item and its value. For multiple selection lists

- * (such as {@link TCheckBoxList} and {@link TListBox}), property

- * {@link getSelectedIndices SelectedIndices} is useful.

- *

- * TListControl implements {@link setAutoPostBack AutoPostBack} which allows

- * a list control to postback the page if the selections of the list items are changed.

- * The {@link setCausesValidation CausesValidation} and {@link setValidationGroup ValidationGroup}

- * properties may be used to specify that validation be performed when auto postback occurs.

- *

- * There are three ways to populate the items in a list control: from template,

- * using {@link setDataSource DataSource} and using {@link setDataSourceID DataSourceID}.

- * The latter two are covered in {@link TDataBoundControl}. To specify items via

- * template, using the following template syntax:

- * <code>

- * <com:TListControl>

- *   <com:TListItem Value="xxx" Text="yyy" >

- *   <com:TListItem Value="xxx" Text="yyy" Selected="true" >

- *   <com:TListItem Value="xxx" Text="yyy" >

- * </com:TListControl>

- * </code>

- *

- * When {@link setDataSource DataSource} or {@link setDataSourceID DataSourceID}

- * is used to populate list items, the {@link setDataTextField DataTextField} and

- * {@link setDataValueField DataValueField} properties are used to specify which

- * columns of the data will be used to populate the text and value of the items.

- * For example, if a data source is as follows,

- * <code>

- * $dataSource=array(

- *    array('name'=>'John', 'age'=>31),

- *    array('name'=>'Cary', 'age'=>28),

- *    array('name'=>'Rose', 'age'=>35),

- * );

- * </code>

- * setting {@link setDataTextField DataTextField} and {@link setDataValueField DataValueField}

- * to 'name' and 'age' will make the first item's text be 'John', value be 31,

- * the second item's text be 'Cary', value be 28, and so on.

- * The {@link setDataTextFormatString DataTextFormatString} property may be further

- * used to format how the item should be displayed. See {@link formatDataValue()}

- * for an explanation of the format string.

+/**
+ * TListControl class
+ *
+ * TListControl is a base class for list controls, such as {@link TListBox},
+ * {@link TDropDownList}, {@link TCheckBoxList}, etc.
+ * It manages the items and their status in a list control.
+ * It also implements how the items can be populated from template and
+ * data source.
+ *
+ * The property {@link getItems} returns a list of the items in the control.
+ * To specify or determine which item is selected, use the
+ * {@link getSelectedIndex SelectedIndex} property that indicates the zero-based
+ * index of the selected item in the item list. You may also use
+ * {@link getSelectedItem SelectedItem} and {@link getSelectedValue SelectedValue}
+ * to get the selected item and its value. For multiple selection lists
+ * (such as {@link TCheckBoxList} and {@link TListBox}), property
+ * {@link getSelectedIndices SelectedIndices} is useful.
+ *
+ * TListControl implements {@link setAutoPostBack AutoPostBack} which allows
+ * a list control to postback the page if the selections of the list items are changed.
+ * The {@link setCausesValidation CausesValidation} and {@link setValidationGroup ValidationGroup}
+ * properties may be used to specify that validation be performed when auto postback occurs.
+ *
+ * There are three ways to populate the items in a list control: from template,
+ * using {@link setDataSource DataSource} and using {@link setDataSourceID DataSourceID}.
+ * The latter two are covered in {@link TDataBoundControl}. To specify items via
+ * template, using the following template syntax:
+ * <code>
+ * <com:TListControl>
+ *   <com:TListItem Value="xxx" Text="yyy" >
+ *   <com:TListItem Value="xxx" Text="yyy" Selected="true" >
+ *   <com:TListItem Value="xxx" Text="yyy" >
+ * </com:TListControl>
+ * </code>
+ *
+ * When {@link setDataSource DataSource} or {@link setDataSourceID DataSourceID}
+ * is used to populate list items, the {@link setDataTextField DataTextField} and
+ * {@link setDataValueField DataValueField} properties are used to specify which
+ * columns of the data will be used to populate the text and value of the items.
+ * For example, if a data source is as follows,
+ * <code>
+ * $dataSource=array(
+ *    array('name'=>'John', 'age'=>31),
+ *    array('name'=>'Cary', 'age'=>28),
+ *    array('name'=>'Rose', 'age'=>35),
+ * );
+ * </code>
+ * setting {@link setDataTextField DataTextField} and {@link setDataValueField DataValueField}
+ * to 'name' and 'age' will make the first item's text be 'John', value be 31,
+ * the second item's text be 'Cary', value be 28, and so on.
+ * The {@link setDataTextFormatString DataTextFormatString} property may be further
+ * used to format how the item should be displayed. See {@link formatDataValue()}
+ * for an explanation of the format string.

- *

- * Examples

- * - At least two selections

- * <code>

- *	<com:TListBox ID="listbox" SelectionMode="Multiple">

- *		<com:TListItem Text="item1" Value="value1" />

- *		<com:TListItem Text="item2" Value="value2" />

- * Markdown is a text-to-HTML conversion tool for web writers. Markdown allows

- * convert it to structurally valid XHTML (or HTML).

- * Further documentation regarding Markdown can be found at

- * http://daringfireball.net/projects/markdown/

- *

- * To use TMarkdown, simply enclose the content to be rendered within

- * the body of TMarkdown in a template.

- *

- * See http://www.pradosoft.com/demos/quickstart/?page=Markdown for

- * details on the Markdown syntax usage.

- *

- * TMarkdown also performs syntax highlighting for code blocks whose language

- * is recognized by {@link TTextHighlighter}.

- * The language of a code block must be specified in the first line of the block

- * and enclosed within a pair of square brackets (e.g. [php]).

+ * convert it to structurally valid XHTML (or HTML).
+ * Further documentation regarding Markdown can be found at
+ * http://daringfireball.net/projects/markdown/
+ *
+ * To use TMarkdown, simply enclose the content to be rendered within
+ * the body of TMarkdown in a template.
+ *
+ * See http://www.pradosoft.com/demos/quickstart/?page=Markdown for
+ * details on the Markdown syntax usage.
+ *
+ * TMarkdown also performs syntax highlighting for code blocks whose language
+ * is recognized by {@link TTextHighlighter}.
+ * The language of a code block must be specified in the first line of the block
+ * and enclosed within a pair of square brackets (e.g. [php]).

- * TMultiView class

- *

- * TMultiView serves as a container for a group of {@link TView} controls.

- * The view collection can be retrieved by {@link getViews Views}.

- * Each view contains child controls. TMultiView determines which view and its

- * child controls are visible. At any time, at most one view is visible (called

- * active). To make a view active, set {@link setActiveView ActiveView} or

- * {@link setActiveViewIndex ActiveViewIndex}.

- *

- * TMultiView also responds to specific command events raised from button controls

- * contained in current active view. A command event with name 'NextView'

- * will cause TMultiView to make the next available view active.

- * Other command names recognized by TMultiView include

- * - PreviousView : switch to previous view

- * - SwitchViewID : switch to a view by its ID path

- * - SwitchViewIndex : switch to a view by its index in the {@link getViews Views} collection.

- *

- * TMultiView raises {@link OnActiveViewChanged OnActiveViewChanged} event

- * when its active view is changed during a postback.

-/**

- * TOutputCache class.

- *

- * TOutputCache enables caching a portion of a Web page, also known as

- * partial caching. The content being cached can be either static or

- * dynamic.

- *

- * To use TOutputCache, simply enclose the content to be cached

- * within the TOutputCache component tag on a template, e.g.,

- * <code>

- * <com:TOutputCache>

- *   content to be cached

- * </com:TOutputCache>

- * </code>

- * where content to be cached can be static text and/or component tags.

- *

- * The validity of the cached content is determined based on two factors:

- * the {@link setDuration Duration} and the cache dependency.

- * The former specifies the number of seconds that the data can remain

- * valid in cache (defaults to 60s), while the latter specifies conditions

- * that the cached data depends on. If a dependency changes,

- * (e.g. relevant data in DB are updated), the cached data will be invalidated.

- *

- * There are two ways to specify cache dependency. One may write event handlers

- * to respond to the {@link onCheckDependency OnCheckDependency} event and set

- * the event parameter's {@link TOutputCacheCheckDependencyEventParameter::getIsValid IsValid}

- * property to indicate whether the cached data remains valid or not.

- * One can also extend TOutputCache and override its {@link getCacheDependency}

- * function. While the former is easier to use, the latter offers more extensibility.

- *

- * The content fetched from cache may be variated with respect to

- * some parameters. It supports variation with respect to request parameters,

- * which is specified by {@link setVaryByParam VaryByParam} property.

- * If a specified request parameter is different, a different version of

- * cached content is used. This is extremely useful if a page's content

- * may be variated according to some GET parameters.

- * The content being cached may also be variated with user sessions if

- * {@link setVaryBySession VaryBySession} is set true.

- * To variate the cached content by other factors, override {@link calculateCacheKey()} method.

- *

- * Output caches can be nested. An outer cache takes precedence over an

- * inner cache. This means, if the content cached by the inner cache expires

- * or is invalidated, while that by the outer cache not, the outer cached

- * content will be used.

- *

- * Note, TOutputCache is effective only for non-postback page requests

- * and when cache module is enabled.

- *

- * Do not attempt to address child controls of TOutputCache when the cached

- * content is to be used. Use {@link getContentCached ContentCached} property

- * to determine whether the content is cached or not.

-/**

- * TPager class.

- *

- * TPager creates a pager that provides UI for end-users to interactively

- * specify which page of data to be rendered in a {@link TDataBoundControl}-derived control,

- * such as {@link TDataList}, {@link TRepeater}, {@link TCheckBoxList}, etc.

- * The target data-bound control is specified by {@link setControlToPaginate ControlToPaginate},

- * which must be the ID path of the target control reaching from the pager's

- * naming container. Note, the target control must have its {@link TDataBoundControl::setAllowPaging AllowPaging}

- * set to true.

- *

- * TPager can display three different UIs, specified via {@link setMode Mode}:

- * - NextPrev: a next page and a previous page button are rendered.

- * - Numeric: a list of page index buttons are rendered.

- * - List: a dropdown list of page indices are rendered.

- *

- * When the pager mode is either NextPrev or Numeric, the paging buttons may be displayed

- * in three types by setting {@link setButtonType ButtonType}:

- * - LinkButton: a hyperlink button

- * - PushButton: a normal button

- * - ImageButton: an image button (please set XXXPageImageUrl properties accordingly to specify the button images.)

- *

- * TPager raises an {@link onPageIndexChanged OnPageIndexChanged} event when

- * the end-user interacts with it and specifies a new page (e.g. clicking

- * on a page button that leads to a new page.) The new page index may be obtained

- * from the event parameter's property {@link TPagerPageChangedEventParameter::getNewPageIndex NewPageIndex}.

- * Normally, in the event handler, one can set the {@link TDataBoundControl::getCurrentPageIndex CurrentPageIndex}

- * to this new page index so that the new page of data is rendered.

- *

- * Multiple pagers can be associated with the same data-bound control.

+ * TPager creates a pager that provides UI for end-users to interactively
+ * specify which page of data to be rendered in a {@link TDataBoundControl}-derived control,
+ * such as {@link TDataList}, {@link TRepeater}, {@link TCheckBoxList}, etc.
+ * The target data-bound control is specified by {@link setControlToPaginate ControlToPaginate},
+ * which must be the ID path of the target control reaching from the pager's
+ * naming container. Note, the target control must have its {@link TDataBoundControl::setAllowPaging AllowPaging}
+ * set to true.
+ *
+ * TPager can display three different UIs, specified via {@link setMode Mode}:
+ * - NextPrev: a next page and a previous page button are rendered.
+ * - Numeric: a list of page index buttons are rendered.
+ * - List: a dropdown list of page indices are rendered.
+ *
+ * When the pager mode is either NextPrev or Numeric, the paging buttons may be displayed
+ * in three types by setting {@link setButtonType ButtonType}:
+ * - LinkButton: a hyperlink button
+ * - PushButton: a normal button
+ * - ImageButton: an image button (please set XXXPageImageUrl properties accordingly to specify the button images.)
+ *
+ * TPager raises an {@link onPageIndexChanged OnPageIndexChanged} event when
+ * the end-user interacts with it and specifies a new page (e.g. clicking
+ * on a page button that leads to a new page.) The new page index may be obtained
+ * from the event parameter's property {@link TPagerPageChangedEventParameter::getNewPageIndex NewPageIndex}.
+ * Normally, in the event handler, one can set the {@link TDataBoundControl::getCurrentPageIndex CurrentPageIndex}
+ * to this new page index so that the new page of data is rendered.
+ *
+ * Multiple pagers can be associated with the same data-bound control.

- * TPanel class

- *

- * TPanel represents a component that acts as a container for other component.

- * It is especially useful when you want to generate components programmatically

- * or hide/show a group of components.

- *

- * By default, TPanel displays a &lt;div&gt; element on a page.

- * Children of TPanel are displayed as the body content of the element.

- * The property {@link setWrap Wrap} can be used to set whether the body content

- * should wrap or not. {@link setHorizontalAlign HorizontalAlign} governs how

- * the content is aligned horizontally, and {@link getDirection Direction} indicates

- * the content direction (left to right or right to left). You can set

- * {@link setBackImageUrl BackImageUrl} to give a background image to the panel,

- * and you can ste {@link setGroupingText GroupingText} so that the panel is

- * displayed as a field set with a legend text. Finally, you can specify

- * a default button to be fired when users press 'return' key within the panel

- * by setting the {@link setDefaultButton DefaultButton} property.

+ * TPanel class
+ *
+ * TPanel represents a component that acts as a container for other component.
+ * It is especially useful when you want to generate components programmatically
+ * or hide/show a group of components.
+ *
+ * By default, TPanel displays a &lt;div&gt; element on a page.
+ * Children of TPanel are displayed as the body content of the element.
+ * The property {@link setWrap Wrap} can be used to set whether the body content
+ * should wrap or not. {@link setHorizontalAlign HorizontalAlign} governs how
+ * the content is aligned horizontally, and {@link getDirection Direction} indicates
+ * the content direction (left to right or right to left). You can set
+ * {@link setBackImageUrl BackImageUrl} to give a background image to the panel,
+ * and you can ste {@link setGroupingText GroupingText} so that the panel is
+ * displayed as a field set with a legend text. Finally, you can specify
+ * a default button to be fired when users press 'return' key within the panel
+ * by setting the {@link setDefaultButton DefaultButton} property.

- * property.

- *

- * To determine whether the TRadioButton component is checked, test the {@link getChecked Checked}

- * TRadioButton uses {@link setGroupName GroupName} to group together a set of radio buttons.

-/**

- * TRangeValidator class

- *

- * TRangeValidator tests whether an input value is within a specified range.

- *

- * TRangeValidator uses three key properties to perform its validation.

- * The {@link setMinValue MinValue} and {@link setMaxValue MaxValue}

- * properties specify the minimum and maximum values of the valid range.

- * The {@link setDataType DataType} property is used to specify the

- * data type of the value and the minimum and maximum range values.

- * These values are converted to this data type before the validation

- * operation is performed. The following value types are supported:

- * - <b>Integer</b> A 32-bit signed integer data type.

- * - <b>Float</b> A double-precision floating point number data type.

- * - <b>Date</b> A date data type. The date format can be specified by

- *   setting {@link setDateFormat DateFormat} property, which must be recognizable

- *   by {@link TSimpleDateFormatter}. If the property is not set,

- *   the GNU date syntax is assumed.

- * - <b>String</b> A string data type.

- * - <b>StringLength</b> check for string length.

- *

- * If {@link setStrictComparison StrictComparison} is true, then the ranges

- * are compared as strictly less than the max value and/or strictly greater than the min value.

- *

- * The TRangeValidator allows a special DataType "StringLength" that

- * can be used to verify minimum and maximum string length. The

- * {@link setCharset Charset} property can be used to force a particular

- * charset for comparison. Otherwise, the application charset is used and is

- * defaulted as UTF-8.

-/**

- * TReCaptcha class.

- *

- * TReCaptcha displays a reCAPTCHA (a token displayed as an image) that can be used

- * to determine if the input is entered by a real user instead of some program. It can

- * also prevent multiple submits of the same form either by accident, or on purpose (ie. spamming).

- *

- * The reCAPTCHA to solve (a string consisting of two separate words) displayed is automatically

- * generated by the reCAPTCHA system at recaptcha.net. However, in order to use the services

- * of the site you will need to register and get a public and a private API key pair, and 

- * supply those to the reCAPTCHA control through setting the {@link setPrivateKey PrivateKey} 

- * and {@link setPublicKey PublicKey} properties. 

- *

- * Currently the reCAPTCHA API supports only one reCAPTCHA field per page, so you MUST make sure that all 

- * your input is protected and validated by a single reCAPTCHA control. Placing more than one reCAPTCHA

- * control on the page will lead to unpredictable results, and the user will most likely unable to solve 

- * any of them successfully.

- *

- * Upon postback, user input can be validated by calling {@link validate()}.

- * The {@link TReCaptchaValidator} control can also be used to do validation, which provides

- * server-side validation. Calling (@link validate()) will invalidate the token supplied, so all consecutive

- * calls to the method - without solving a new captcha - will return false. Therefore if implementing a multi-stage

- * input process, you must make sure that you call validate() only once, either at the end of the input process, or 

- * you store the result till the end of the processing.

- *

- * The following template shows a typical use of TReCaptcha control:

- * <code>

- * <com:TReCaptcha ID="Captcha"

- *                 PublicKey="..."

- *                 PrivateKey="..."

- * />

- * <com:TReCaptchaValidator ControlToValidate="Captcha"

- *                          ErrorMessage="You are challenged!" />

- * </code>

+/**
+ * TReCaptcha class.
+ *
+ * TReCaptcha displays a reCAPTCHA (a token displayed as an image) that can be used
+ * to determine if the input is entered by a real user instead of some program. It can
+ * also prevent multiple submits of the same form either by accident, or on purpose (ie. spamming).
+ *
+ * The reCAPTCHA to solve (a string consisting of two separate words) displayed is automatically
+ * generated by the reCAPTCHA system at recaptcha.net. However, in order to use the services
+ * of the site you will need to register and get a public and a private API key pair, and 
+ * supply those to the reCAPTCHA control through setting the {@link setPrivateKey PrivateKey} 
+ * and {@link setPublicKey PublicKey} properties. 
+ *
+ * Currently the reCAPTCHA API supports only one reCAPTCHA field per page, so you MUST make sure that all 
+ * your input is protected and validated by a single reCAPTCHA control. Placing more than one reCAPTCHA
+ * control on the page will lead to unpredictable results, and the user will most likely unable to solve 
+ * any of them successfully.
+ *
+ * Upon postback, user input can be validated by calling {@link validate()}.
+ * The {@link TReCaptchaValidator} control can also be used to do validation, which provides
+ * server-side validation. Calling (@link validate()) will invalidate the token supplied, so all consecutive
+ * calls to the method - without solving a new captcha - will return false. Therefore if implementing a multi-stage
+ * input process, you must make sure that you call validate() only once, either at the end of the input process, or 
+ * you store the result till the end of the processing.
+ *
+ * The following template shows a typical use of TReCaptcha control:
+ * <code>
+ * <com:TReCaptcha ID="Captcha"
+ *                 PublicKey="..."
+ *                 PrivateKey="..."
+ * />
+ * <com:TReCaptchaValidator ControlToValidate="Captcha"
+ *                          ErrorMessage="You are challenged!" />
+ * </code>

-/**

- * TRepeater class.

- *

- * TRepeater displays its content repeatedly based on the data fetched from

- * {@link setDataSource DataSource}.

- * The repeated contents in TRepeater are called items, which are controls and

- * can be accessed through {@link getItems Items}. When {@link dataBind()} is invoked,

- * TRepeater creates an item for each row of data and binds the data row to the item.

- * Optionally, a repeater can have a header, a footer and/or separators between items.

- *

- * The layout of the repeated contents are specified by inline templates.

- * Repeater items, header, footer, etc. are being instantiated with the corresponding

- * templates when data is being bound to the repeater.

- *

- * Since v3.1.0, the layout can also be specified by renderers. A renderer is a control class

- * that can be instantiated as repeater items, header, etc. A renderer can thus be viewed

- * as an external template (in fact, it can also be non-templated controls).

- *

- * A renderer can be any control class.

- * - If the class implements {@link IDataRenderer}, the <b>Data</b>

- * property will be set as the data row during databinding. Many PRADO controls

- * implement this interface, such as {@link TLabel}, {@link TTextBox}, etc.

- * - If the class implements {@link IItemDataRenderer}, the <b>ItemIndex</b> property will be set

- * as the zero-based index of the item in the repeater item collection, and

- * the <b>ItemType</b> property as the item's type (such as TListItemType::Item).

- * {@link TRepeaterItemRenderer} may be used as the convenient base class which

- * already implements {@link IDataItemRenderer}.

- *

- * The following properties are used to specify different types of template and renderer

- * for a repeater:

- * - {@link setItemTemplate ItemTemplate}, {@link setItemRenderer ItemRenderer}:

- * for each repeated row of data

- * - {@link setAlternatingItemTemplate AlternatingItemTemplate}, {@link setAlternatingItemRenderer AlternatingItemRenderer}:

- * for each alternating row of data. If not set, {@link setItemTemplate ItemTemplate} or {@link setItemRenderer ItemRenderer}

- * will be used instead.

- * - {@link setHeaderTemplate HeaderTemplate}, {@link setHeaderRenderer HeaderRenderer}:

- * for the repeater header.

- * - {@link setFooterTemplate FooterTemplate}, {@link setFooterRenderer FooterRenderer}:

- * for the repeater footer.

- * - {@link setSeparatorTemplate SeparatorTemplate}, {@link setSeparatorRenderer SeparatorRenderer}:

- * for content to be displayed between items.

- * - {@link setEmptyTemplate EmptyTemplate}, {@link setEmptyRenderer EmptyRenderer}:

- * used when data bound to the repeater is empty.

- *

- * If a content type is defined with both a template and a renderer, the latter takes precedence.

- *

- * When {@link dataBind()} is being called, TRepeater undergoes the following lifecycles for each row of data:

- * - create item based on templates or renderers

- * - set the row of data to the item

- * - raise {@link onItemCreated OnItemCreated}:

- * - add the item as a child control

- * - call dataBind() of the item

- * - raise {@link onItemDataBound OnItemDataBound}:

- *

- * TRepeater raises an {@link onItemCommand OnItemCommand} whenever a button control

- * within some repeater item raises a <b>OnCommand</b> event. Therefore,

- * you can handle all sorts of <b>OnCommand</b> event in a central place by

- * writing an event handler for {@link onItemCommand OnItemCommand}.

- *

- * When a page containing a repeater is post back, the repeater will restore automatically

- * all its contents, including items, header, footer and separators.

- * However, the data row associated with each item will not be recovered and become null.

- * To access the data, use one of the following ways:

- * - Use {@link getDataKeys DataKeys} to obtain the data key associated with

- * the specified repeater item and use the key to fetch the corresponding data

- * from some persistent storage such as DB.

- * - Save the whole dataset in viewstate, which will restore the dataset automatically upon postback.

- * Be aware though, if the size of your dataset is big, your page size will become big. Some

- * complex data may also have serializing problem if saved in viewstate.

+/**
+ * TRepeater class.
+ *
+ * TRepeater displays its content repeatedly based on the data fetched from
+ * {@link setDataSource DataSource}.
+ * The repeated contents in TRepeater are called items, which are controls and
+ * can be accessed through {@link getItems Items}. When {@link dataBind()} is invoked,
+ * TRepeater creates an item for each row of data and binds the data row to the item.
+ * Optionally, a repeater can have a header, a footer and/or separators between items.
+ *
+ * The layout of the repeated contents are specified by inline templates.
+ * Repeater items, header, footer, etc. are being instantiated with the corresponding
+ * templates when data is being bound to the repeater.
+ *
+ * Since v3.1.0, the layout can also be specified by renderers. A renderer is a control class
+ * that can be instantiated as repeater items, header, etc. A renderer can thus be viewed
+ * as an external template (in fact, it can also be non-templated controls).
+ *
+ * A renderer can be any control class.
+ * - If the class implements {@link IDataRenderer}, the <b>Data</b>
+ * property will be set as the data row during databinding. Many PRADO controls
+ * implement this interface, such as {@link TLabel}, {@link TTextBox}, etc.
+ * - If the class implements {@link IItemDataRenderer}, the <b>ItemIndex</b> property will be set
+ * as the zero-based index of the item in the repeater item collection, and
+ * the <b>ItemType</b> property as the item's type (such as TListItemType::Item).
+ * {@link TRepeaterItemRenderer} may be used as the convenient base class which
+ * already implements {@link IDataItemRenderer}.
+ *
+ * The following properties are used to specify different types of template and renderer
+ * for a repeater:
+ * - {@link setItemTemplate ItemTemplate}, {@link setItemRenderer ItemRenderer}:
+ * for each repeated row of data
+ * - {@link setAlternatingItemTemplate AlternatingItemTemplate}, {@link setAlternatingItemRenderer AlternatingItemRenderer}:
+ * for each alternating row of data. If not set, {@link setItemTemplate ItemTemplate} or {@link setItemRenderer ItemRenderer}
+ * will be used instead.
+ * - {@link setHeaderTemplate HeaderTemplate}, {@link setHeaderRenderer HeaderRenderer}:
+ * for the repeater header.
+ * - {@link setFooterTemplate FooterTemplate}, {@link setFooterRenderer FooterRenderer}:
+ * for the repeater footer.
+ * - {@link setSeparatorTemplate SeparatorTemplate}, {@link setSeparatorRenderer SeparatorRenderer}:
+ * for content to be displayed between items.
+ * - {@link setEmptyTemplate EmptyTemplate}, {@link setEmptyRenderer EmptyRenderer}:
+ * used when data bound to the repeater is empty.
+ *
+ * If a content type is defined with both a template and a renderer, the latter takes precedence.
+ *
+ * When {@link dataBind()} is being called, TRepeater undergoes the following lifecycles for each row of data:
+ * - create item based on templates or renderers
+ * - set the row of data to the item
+ * - raise {@link onItemCreated OnItemCreated}:
+ * - add the item as a child control
+ * - call dataBind() of the item
+ * - raise {@link onItemDataBound OnItemDataBound}:
+ *
+ * TRepeater raises an {@link onItemCommand OnItemCommand} whenever a button control
+ * within some repeater item raises a <b>OnCommand</b> event. Therefore,
+ * you can handle all sorts of <b>OnCommand</b> event in a central place by
+ * writing an event handler for {@link onItemCommand OnItemCommand}.
+ *
+ * When a page containing a repeater is post back, the repeater will restore automatically
+ * all its contents, including items, header, footer and separators.
+ * However, the data row associated with each item will not be recovered and become null.
+ * To access the data, use one of the following ways:
+ * - Use {@link getDataKeys DataKeys} to obtain the data key associated with
+ * the specified repeater item and use the key to fetch the corresponding data
+ * from some persistent storage such as DB.
+ * - Save the whole dataset in viewstate, which will restore the dataset automatically upon postback.
+ * Be aware though, if the size of your dataset is big, your page size will become big. Some
+ * complex data may also have serializing problem if saved in viewstate.

-/**

- * TSlider class

- *

- * TSlider displays a slider for numeric input purpose. A slider consists of a 'track',

- * which define the range of possible value, and a 'handle' which can slide on the track, to select

- * a value in the range. The track can be either Horizontal or Vertical, depending of the {@link SetDirection Direction}

- * property. By default, it's horizontal.

- *

- * The range boundaries are defined by {@link SetMinValue MinValue} and {@link SetMaxValue MaxValue} properties.

- * The default range is from 0 to 100.

- * The {@link SetStepSize StepSize} property can be used to define the <b>step</b> between 2 values inside the range.

- * Notice that this step will be recomputed if there is more than 200 values between the range boundaries.

- * You can also provide the allowed values by setting the {@link SetValues Values} array.

- *

- * A 'Progress Indicator' can be displayed within the track with the {@link SetProgressIndicator ProgressIndicator} property.

- * 

- * The TSlider control can be easily customized using CssClasses. You can provide your own css file, using the

- * {@link SetCssUrl CssUrl} property.

- * The css class for TSlider can be set by the {@link setCssClass CssClass} property. Default value is "Slider HorizontalSlider" 

- * for an horizontal slider, and "Slider VerticalSlider" for a vertical one.

- *

- * If {@link SetAutoPostBack AutoPostBack} property is true, postback is sent as soon as the value changed.

- *

- * TSlider raises the {@link onValueChanged} event when the value of the slider has changed during postback.

- *

- * You can also attach ClientSide javascript events handler to the slider :

- * - ClientSide.onSlide is called when the handle is slided on the track. You can get the current value in the <b>value</b>

- * javascript variable. You can use this event to update on client side a label with the current value

- * - ClientSide.onChange is called when the slider value has changed (at the end of a move).

+/**
+ * TSlider class
+ *
+ * TSlider displays a slider for numeric input purpose. A slider consists of a 'track',
+ * which define the range of possible value, and a 'handle' which can slide on the track, to select
+ * a value in the range. The track can be either Horizontal or Vertical, depending of the {@link SetDirection Direction}
+ * property. By default, it's horizontal.
+ *
+ * The range boundaries are defined by {@link SetMinValue MinValue} and {@link SetMaxValue MaxValue} properties.
+ * The default range is from 0 to 100.
+ * The {@link SetStepSize StepSize} property can be used to define the <b>step</b> between 2 values inside the range.
+ * Notice that this step will be recomputed if there is more than 200 values between the range boundaries.
+ * You can also provide the allowed values by setting the {@link SetValues Values} array.
+ *
+ * A 'Progress Indicator' can be displayed within the track with the {@link SetProgressIndicator ProgressIndicator} property.
+ * 
+ * The TSlider control can be easily customized using CssClasses. You can provide your own css file, using the
+ * {@link SetCssUrl CssUrl} property.
+ * The css class for TSlider can be set by the {@link setCssClass CssClass} property. Default value is "Slider HorizontalSlider" 
+ * for an horizontal slider, and "Slider VerticalSlider" for a vertical one.
+ *
+ * If {@link SetAutoPostBack AutoPostBack} property is true, postback is sent as soon as the value changed.
+ *
+ * TSlider raises the {@link onValueChanged} event when the value of the slider has changed during postback.
+ *
+ * You can also attach ClientSide javascript events handler to the slider :
+ * - ClientSide.onSlide is called when the handle is slided on the track. You can get the current value in the <b>value</b>
+ * javascript variable. You can use this event to update on client side a label with the current value
+ * - ClientSide.onChange is called when the slider value has changed (at the end of a move).

-/**

- * TTable class

- *

- * TTable displays an HTML table on a Web page.

- *

- * A table may have {@link setCaption Caption}, whose alignment is specified

- * via {@link setCaptionAlign CaptionAlign}. The table cellpadding and cellspacing

- * are specified via {@link setCellPadding CellPadding} and {@link setCellSpacing CellSpacing}

- * properties, respectively. The {@link setGridLines GridLines} specifies how

- * the table should display its borders. The horizontal alignment of the table

- * content can be specified via {@link setHorizontalAlign HorizontalAlign},

- * and {@link setBackImageUrl BackImageUrl} can assign a background image to the table.

- *

- * A TTable maintains a list of {@link TTableRow} controls in its

- * {@link getRows Rows} property. Each {@link TTableRow} represents

- * an HTML table row.

- *

- * To populate the table {@link getRows Rows}, you may either use control template

- * or dynamically create {@link TTableRow} in code.

- * In template, do as follows to create the table rows and cells,

- * <code>

- *   <com:TTable>

- *     <com:TTableRow>

- *       <com:TTableCell Text="content" />

- *       <com:TTableCell Text="content" />

- *     </com:TTableRow>

- *     <com:TTableRow>

- *       <com:TTableCell Text="content" />

- *       <com:TTableCell Text="content" />

- *     </com:TTableRow>

- *   </com:TTable>

- * </code>

- * The above can also be accomplished in code as follows,

- * <code>

- *   $table=new TTable;

- *   $row=new TTableRow;

- *   $cell=new TTableCell; $cell->Text="content"; $row->Cells->add($cell);

- *   $cell=new TTableCell; $cell->Text="content"; $row->Cells->add($cell);

- *   $table->Rows->add($row);

- *   $row=new TTableRow;

- *   $cell=new TTableCell; $cell->Text="content"; $row->Cells->add($cell);

- *   $cell=new TTableCell; $cell->Text="content"; $row->Cells->add($cell);

- *   $table->Rows->add($row);

- * </code>

+ * <code>
+ *   <com:TTable>
+ *     <com:TTableRow>
+ *       <com:TTableCell Text="content" />

-/**

- * TTextBox class

- *

- * TTextBox displays a text box on the Web page for user input.

- * The text displayed in the TTextBox control is determined by the

- * {@link setText Text} property. You can create a <b>SingleLine</b>,

- * a <b>MultiLine</b>, or a <b>Password</b> text box by setting

- * the {@link setTextMode TextMode} property. If the TTextBox control

- * is a multiline text box, the number of rows it displays is determined

- * by the {@link setRows Rows} property, and the {@link setWrap Wrap} property

- * can be used to determine whether to wrap the text in the component.

- *

- * To specify the display width of the text box, in characters, set

- * the {@link setColumns Columns} property. To prevent the text displayed

- * in the component from being modified, set the {@link setReadOnly ReadOnly}

- * property to true. If you want to limit the user input to a specified number

- * of characters, set the {@link setMaxLength MaxLength} property.

- * To use AutoComplete feature, set the {@link setAutoCompleteType AutoCompleteType} property.

- *

- * If {@link setAutoPostBack AutoPostBack} is set true, updating the text box

- * and then changing the focus out of it will cause postback action.

- * And if {@link setCausesValidation CausesValidation} is true, validation will

- * also be processed, which can be further restricted within

- * a {@link setValidationGroup ValidationGroup}.

- *

- * WARNING: Be careful if you want to display the text collected via TTextBox.

- * Malicious cross-site script may be injected in. You may use {@link getSafeText SafeText}

- * to prevent this problem.

- *

- * NOTE: If you set {@link setWrap Wrap} to false or use {@link setAutoCompleteType AutoCompleteType},

- * the generated HTML output for the textbox will not be XHTML-compatible.

- * Currently, no alternatives are available.

+/**
+ * TTextBox class
+ *
+ * TTextBox displays a text box on the Web page for user input.
+ * The text displayed in the TTextBox control is determined by the
+ * {@link setText Text} property. You can create a <b>SingleLine</b>,
+ * a <b>MultiLine</b>, or a <b>Password</b> text box by setting
+ * the {@link setTextMode TextMode} property. If the TTextBox control
+ * is a multiline text box, the number of rows it displays is determined
+ * by the {@link setRows Rows} property, and the {@link setWrap Wrap} property
+ * can be used to determine whether to wrap the text in the component.
+ *
+ * To specify the display width of the text box, in characters, set
+ * the {@link setColumns Columns} property. To prevent the text displayed
+ * in the component from being modified, set the {@link setReadOnly ReadOnly}
+ * property to true. If you want to limit the user input to a specified number
+ * of characters, set the {@link setMaxLength MaxLength} property.
+ * To use AutoComplete feature, set the {@link setAutoCompleteType AutoCompleteType} property.
+ *
+ * If {@link setAutoPostBack AutoPostBack} is set true, updating the text box
+ * and then changing the focus out of it will cause postback action.
+ * And if {@link setCausesValidation CausesValidation} is true, validation will
+ * also be processed, which can be further restricted within
+ * a {@link setValidationGroup ValidationGroup}.
+ *
+ * WARNING: Be careful if you want to display the text collected via TTextBox.
+ * Malicious cross-site script may be injected in. You may use {@link getSafeText SafeText}
+ * to prevent this problem.
+ *
+ * NOTE: If you set {@link setWrap Wrap} to false or use {@link setAutoCompleteType AutoCompleteType},
+ * the generated HTML output for the textbox will not be XHTML-compatible.
+ * Currently, no alternatives are available.

-/**

- * Class TWizard.

- *

- * TWizard splits a large form and presents the user with a series of smaller

- * forms to complete. TWizard is analogous to the installation wizard commonly

- * used to install software in Windows.

- *

- * The smaller forms are called wizard steps ({@link TWizardStep}, which can be accessed via

- * {@link getWizardSteps WizardSteps}. In template, wizard steps can be added

- * into a wizard using the following syntax,

- * <code>

- *   <com:TWizard>

- *      <com:TWizardStep Title="step 1">

- *          content in step 1, may contain other controls

- *      </com:TWizardStep>

- *      <com:TWizardStep Title="step 2">

- *          content in step 2, may contain other controls

- *      </com:TWizardStep>

- *   </com:TWizard>

- * </code>

- *

- * Each wizard step can be one of the following types:

- * - Start : the first step in the wizard.

- * - Step : the internal steps in the wizard.

- * - Finish : the last step that allows user interaction.

- * - Complete : the step that shows a summary to user (no interaction is allowed).

- * - Auto : the step type is determined by wizard automatically.

- * At any time, only one step is visible to end-users, which can be obtained

- * by {@link getActiveStep ActiveStep}. Its index in the step collection is given by

- * {@link getActiveStepIndex ActiveStepIndex}.

- *

- * Wizard content can be customized in many ways.

- *

- * The layout of a wizard consists of four parts: header, step content, navigation

- * and side bar. Their content are affected by the following properties, respectively,

- * - header: {@link setHeaderText HeaderText} and {@link setHeaderTemplate HeaderTemplate}.

- *   If both are present, the latter takes precedence.

- * - step: {@link getWizardSteps WizardSteps}.

- * - navigation: {@link setStartNavigationTemplate StartNavigationTemplate},

- *   {@link setStepNavigationTemplate StepNavigationTemplate},

- *   {@link setFinishNavigationTemplate FinishNavigationTemplate}.

- *   Default templates will be used if above templates are not set.

- * - side bar: {@link setSideBarTemplate SideBarTemplate}.

- *   A default template will be used if this template is not set.

- *   Its visibility is toggled by {@link setShowSideBar ShowSideBar}.

- *

- * The style of these wizard layout components can be customized via the following style properties,

- * - header: {@link getHeaderStyle HeaderStyle}.

- * - step: {@link getStepStyle StepStyle}.

- * - navigation: {@link getNavigationStyle NavigationStyle},

- *   {@link getStartNextButtonStyle StartNextButtonStyle},

- *   {@link getStepNextButtonStyle StepNextButtonStyle},

- *   {@link getStepPreviousButtonStyle StepPreviousButtonStyle},

- *   {@link getFinishPreviousButtonStyle FinishPreviousButtonStyle},

- *   {@link getFinishCompleteButtonStyle FinishCompleteButtonStyle},

- *   {@link getCancelButtonStyle CancelButtonStyle}.

- * - side bar: {@link getSideBarStyle SideBarStyle} and {@link getSideBarButtonStyle SideBarButtonStyle}.

+/**
+ * Class TWizard.
+ *
+ * TWizard splits a large form and presents the user with a series of smaller
+ * forms to complete. TWizard is analogous to the installation wizard commonly
+ * used to install software in Windows.
+ *
+ * The smaller forms are called wizard steps ({@link TWizardStep}, which can be accessed via
+ * {@link getWizardSteps WizardSteps}. In template, wizard steps can be added
+ * into a wizard using the following syntax,
+ * <code>
+ *   <com:TWizard>
+ *      <com:TWizardStep Title="step 1">
+ *          content in step 1, may contain other controls
+ *      </com:TWizardStep>
+ *      <com:TWizardStep Title="step 2">
+ *          content in step 2, may contain other controls
+ *      </com:TWizardStep>
+ *   </com:TWizard>
+ * </code>
+ *
+ * Each wizard step can be one of the following types:
+ * - Start : the first step in the wizard.
+ * - Step : the internal steps in the wizard.
+ * - Finish : the last step that allows user interaction.
+ * - Complete : the step that shows a summary to user (no interaction is allowed).
+ * - Auto : the step type is determined by wizard automatically.
+ * At any time, only one step is visible to end-users, which can be obtained
+ * by {@link getActiveStep ActiveStep}. Its index in the step collection is given by
+ * {@link getActiveStepIndex ActiveStepIndex}.
+ *
+ * Wizard content can be customized in many ways.
+ *
+ * The layout of a wizard consists of four parts: header, step content, navigation
+ * and side bar. Their content are affected by the following properties, respectively,
+ * - header: {@link setHeaderText HeaderText} and {@link setHeaderTemplate HeaderTemplate}.
+ *   If both are present, the latter takes precedence.
+ * - step: {@link getWizardSteps WizardSteps}.
+ * - navigation: {@link setStartNavigationTemplate StartNavigationTemplate},
+ *   {@link setStepNavigationTemplate StepNavigationTemplate},
+ *   {@link setFinishNavigationTemplate FinishNavigationTemplate}.
+ *   Default templates will be used if above templates are not set.
+ * - side bar: {@link setSideBarTemplate SideBarTemplate}.
+ *   A default template will be used if this template is not set.
+ *   Its visibility is toggled by {@link setShowSideBar ShowSideBar}.
+ *
+ * The style of these wizard layout components can be customized via the following style properties,
+ * - header: {@link getHeaderStyle HeaderStyle}.
+ * - step: {@link getStepStyle StepStyle}.
+ * - navigation: {@link getNavigationStyle NavigationStyle},
+ *   {@link getStartNextButtonStyle StartNextButtonStyle},
+ *   {@link getStepNextButtonStyle StepNextButtonStyle},
+ *   {@link getStepPreviousButtonStyle StepPreviousButtonStyle},
+ *   {@link getFinishPreviousButtonStyle FinishPreviousButtonStyle},
+ *   {@link getFinishCompleteButtonStyle FinishCompleteButtonStyle},
+ *   {@link getCancelButtonStyle CancelButtonStyle}.
+ * - side bar: {@link getSideBarStyle SideBarStyle} and {@link getSideBarButtonStyle SideBarButtonStyle}.
