RadAjaxLoadingPanel
RadAjaxPanel is one of the two major controls of the Telerik RadAjax suite. The other one is RadAjaxManager. The RadAjaxPanel control provides the easiest way to AJAX-enable ASP.NET web control(s). To do this you simply need to place the controls that you want ajaxified into RadAjaxPanel and Telerik RadAjax takes care of the rest. Best of all this happens transparently to the framework and the controls that are being ajaxified.
