-/**

- * TBaseValidator class

- *

- * TBaseValidator serves as the base class for validator controls.

- *

- * Validation is performed when a button control, such a TButton, a TLinkButton

- * or a TImageButton is clicked and the <b>CausesValidation</b> of these controls is true.

- * You can also manually perform validation by using the validate() method of the TPage class.

- *

- * Validator controls always validate the associated input control on the server.

- * TValidation controls also have complete client-side implementation that allow

- * DHTML supported browsers to perform validation on the client via Javascript.

- * Client-side validation will validate user input before it is sent to the server.

- * The form data will not be submitted if any error is detected. This avoids

- *  the round-trip of information necessary for server-side validation.

- *

- * You can use multiple validator controls to validate an individual input control,

- * each responsible for validating different criteria. For example, on a user registration

- * form, you may want to make sure the user enters a value in the username text box,

- * and the input must consist of only word characters. You can use a TRequiredFieldValidator

- * to ensure the input of username and a TRegularExpressionValidator to ensure the proper

- * input.

- *

- * If an input control fails validation, the text specified by the <b>ErrorMessage</b>

- * property is displayed in the validation control. If the <b>Text</b> property is set

- * it will be displayed instead, however. If both <b>ErrorMessage</b> and <b>Text</b>

- * are empty, the body content of the validator will be displayed.

- *

- * You can also place a <b>TValidationSummary</b> control on the page to display error messages

- * from the validators together. In this case, only the <b>ErrorMessage</b> property of the

- * validators will be displayed in the TValidationSummary control.

- *

- * Note, the <b>IsValid</b> property of the current TPage instance will be automatically

- * updated by the validation process which occurs after <b>OnLoad</b> of TPage and

- * before the postback events. Therefore, if you use the <b>IsValid</b>

- * property in the <b>OnLoad</b> event of TPage, you must first explicitly call

- * the validate() method of TPage. As an alternative, you can place your code

- * in the postback event handler, such as <b>OnClick</b> or <b>OnCommand</b>,

- * instead of <b>OnLoad</b> event.

- *

- * Note, to use validators derived from this control, you have to

- * copy the file "<framework>/js/prado_validator.js" to the "js" directory

- * which should be under the directory containing the entry script file.

- *

- * <b>Notes to Inheritors</b>  When you inherit from the TBaseValidator class,

- * you must override the method {@link evaluateIsValid}.

- *

- * Namespace: System.Web.UI.WebControls

- *

- * Properties

- * - <b>EnableClientScript</b>, boolean, default=true, kept in viewstate

- *   <br>Gets or sets a value indicating whether client-side validation is enabled.

- * - <b>Display</b>, string, default=Static, kept in viewstate

- *   <br>Gets or sets the display behavior (None, Static, Dynamic) of the error message in a validation control.

- * - <b>ControlToValidate</b>, string, kept in viewstate

- *   <br>Gets or sets the input control to validate. This property must be set to

- *   the ID path of an input control. The ID path is the dot-connected IDs of

- *   the controls reaching from the validator's parent control to the target control.

- *   For example, if HomePage is the parent of Validator and SideBar controls, and

- *   SideBar is the parent of UserName control, then the ID path for UserName

- *   would be "SideBar.UserName" if UserName is to be validated by Validator.

- * - <b>Text</b>, string, kept in viewstate

- *   <br>Gets or sets the text of TBaseValidator control.

- * - <b>ErrorMessage</b>, string, kept in viewstate

- *   <br>Gets or sets the text for the error message.

- * - <b>EncodeText</b>, boolean, default=true, kept in viewstate

- *   <br>Gets or sets the value indicating whether Text and ErrorMessage should be HTML-encoded when rendering.

- * - <b>IsValid</b>, boolean, default=true

- *   <br>Gets or sets a value that indicates whether the associated input control passes validation.
