This example illustrates how easy it is to AJAX-enable an ASP.NET control. By simply wrapping a standard (or custom) control in a RadAjaxPanel, all postbacks that it performs will be converted to AJAX requests without writing a single line of code. All events handlers, viewstate and form data are preserved and the page lifecycle goes on as normal. By switching on/off the AJAX you can see how the Grid works when it is AJAX-enabled and when you disable the AJAX by setting EnableAjax property of RadAjaxPanel to false.

About RadAjaxPanel for ASP.NET AJAX

RadAjaxPanel provides the easiest way to Ajax-enable ASP.NET web controls. You simply need to place the controls that you want Ajax-enabled into a RadAjaxPanel and Telerik RadAjax takes care of the rest. Best of all, this happens transparently to the framework and the controls that are being Ajax-enabled.

Key Features

  • Ajax-enables all controls inside that normally work with postbacks
  • Defines visually and codeless (in Visual Studio design-time) which elements should be updated via AJAX requests. All elements wrapped in the panel will be updated via AJAX.
  • No need to modify your application logic
  • Allows you to update a number of page elements at once
  • No need to write any JavaScript or invoke AJAX requests manually
