/**

 * <b>Please note:</b> it is highly recommended to set a control's ID
 * attribute when dealing with Ajax requests.

 * The CSS selector is calculated as follows:

 *       it's "<tt>class</tt>" attribute selector will be returned. For example:
 *       <tt>a[class=red]</tt>. <b>Please note:</b> if the link class attribute is
 *       not set, the class attribute will be set to its name, prefixed with
 *       a dash, '-'. For example: <tt>a[class=-my-link]</tt>.
 *       </li>

 *       <li>if the control is not an ActionLink, it is assumed the control
