-/**
- * TButton class
- *
- * TButton creates a click 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 TButton
- * 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 TButton 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.
- *
- * TButton displays the {@link setText Text} property as the button caption.

-/**
- * TCheckBox class
- *
- * TCheckBox displays a check box on the page.
- * You can specify the caption to display beside the check box by setting
- * the {@link setText Text} property. The caption can appear either on the right
- * or left of the check box, which is determined by the {@link setTextAlign TextAlign}
- * property.
- *
- * To determine whether the TCheckBox component is checked, test the {@link getChecked Checked}
- * property. The {@link onCheckedChanged OnCheckedChanged} event is raised when
- * the {@link getChecked Checked} state of the TCheckBox component changes
- * between posts to the server. You can provide an event handler for
- * the {@link onCheckedChanged OnCheckedChanged} event to to programmatically
- * control the actions performed when the state of the TCheckBox component changes
- * between posts to the server.
- *
- * If {@link setAutoPostBack AutoPostBack} is set true, changing the check box state
- * 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}.
- *
- * Note, {@link setText Text} is rendered as is. Make sure it does not contain unwanted characters
- * that may bring security vulnerabilities.

-/**
- * 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.

-/**
- * 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 <img> tag as the body of TLinkButton.

-/**
- * 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.

-/**
- * TRadioButton class
- *
- * TRadioButton displays a radio button on the page.
- * You can specify the caption to display beside the radio buttonby setting
- * the {@link setText Text} property. The caption can appear either on the right
- * or left of the radio button, which is determined by the {@link setTextAlign TextAlign}
- * property.
- *
- * To determine whether the TRadioButton component is checked, test the {@link getChecked Checked}
- * property. The {@link onCheckedChanged OnCheckedChanged} event is raised when
- * the {@link getChecked Checked} state of the TRadioButton component changes
- * between posts to the server. You can provide an event handler for
- * the {@link onCheckedChanged OnCheckedChanged} event to to programmatically
- * control the actions performed when the state of the TRadioButton component changes
- * between posts to the server.
- *
- * TRadioButton uses {@link setGroupName GroupName} to group together a set of radio buttons.
- *
- * If {@link setAutoPostBack AutoPostBack} is set true, changing the radio button state
- * 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}.
- *
- * Note, {@link setText Text} is rendered as is. Make sure it does not contain unwanted characters
- * that may bring security vulnerabilities.
