RadControls for ASP.NET AJAX With RadAjaxManager in your MasterPage you can ajaxify and update every single control in your application. The example below shows how this could be achieved adding the necessary AJAX settings programmatically.
This sample application contains buttons in the the master and content page. The two buttons update controls in the master and content page as well. See the code below for details:
