+ * 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 <b>CommandName</b> property)
- * and a command parameter (specified by <b>CommandParameter</b> 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 the <b>OnCommand</b> event to programmatically control
- * the actions performed when the command button is clicked.
- * In the event handler, you can also determine
- * the <b>CommandName</b> property value and the <b>CommandParameter</b> property value
- * through <b>name</b> and <b>parameter</b> of the event parameter which is of
- * type <b>TCommandEventParameter</b>.
+ * 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 Command} 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 <b>OnClick</b> event to programmatically
- * control the actions performed when the submit button is clicked.
+ * You can provide an event handler for the {@link onClick Click} event
+ * to programmatically control the actions performed when the submit button is clicked.
*
- * TLinkButton will display the <b>Text</b> property value as the hyperlink text. If <b>Text</b>
- * 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.
+ * By default, clicking on a TLinkButton will cause input validation (if any)
+ * to be performed. You can turn this on or off by setting
+ * the {@link setCausesValidation CausesValidation} property.
+ * If validation is successful, the data will be post back to the same page.
+ * You can change the postback target by setting the {@link setPostBackUrl PostBackUrl}
+ * property.
*
- * Note, <b>Text</b> will be HTML encoded before it is displayed in the TLinkButton component.
- * If you don't want it to be so, set <b>EncodeText</b> to false.
+ * To set the client-side javascript associated with the user's click action,
+ * use the {@link setOnClientClick OnClientClick} property. The value will be rendered
+ * as the <b>onclick</b> attribute of the link button.
*
- * Namespace: System.Web.UI.WebControls
- *
- * Properties
- * - <b>Text</b>, string, kept in viewstate
- * <br>Gets or sets the text caption displayed in the TLinkButton component.
- * - <b>EncodeText</b>, boolean, default=true, kept in viewstate
- * <br>Gets or sets the value indicating whether Text should be HTML-encoded when rendering.
- * - <b>CausesValidation</b>, boolean, default=true, kept in viewstate
- * <br>Gets or sets a value indicating whether validation is performed when the TLinkButton component is clicked.
- * - <b>CommandName</b>, string, kept in viewstate
- * <br>Gets or sets the command name associated with the TLinkButton component that is passed to
- * the <b>OnCommand</b> event.
- * - <b>CommandParameter</b>, string, kept in viewstate
- * <br>Gets or sets an optional parameter passed to the <b>OnCommand</b> event along with
