	/// Interface for controls that do no inherit from AjaxControl and want to receive
	/// AjaxCall events. ('Session/Cache' page storing modes)
	/// </summary>
	/// <remarks>
	/// The Load event of the page and its child controls is not raised during an AjaxCall
	/// for 'Session/Cache' page storing modes. If you want to handle the AjaxCall event
	/// instead, implement the IAjaxCallEventHandler on the page or on a custom control.
	/// </remarks>
	/// <example>
	///	public class CustomTextBox : System.Web.UI.WebControls.TextBox, IAjaxCallEventHandler
	///	{
	///		public void RaiseAjaxCallStartEvent()
	///		{
	///			OnAjaxCallStart(EventArgs.Empty);
	///		}
	///		public void RaiseAjaxCallEndEvent()
	///		{
	///			OnAjaxCallEnd(EventArgs.Empty);
