-/**
- * 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.
