When you use a MasterPage with a menu and navigate between you’re content pages in normal ASP .NET, you will see a brief flickering, caused by the ASP .NET postback. You can prevent this flickering by ajaxifying the postback.

This can be done by using the Telerik RadAjaxPanel. In my case I used LinkButtons in the masterpage for navigating the content pages and surrounded the Linbuttons by a Telerik RadAjaxPanel. The click events of the LinkButtons use Reponse.Redirect to navigate between the content pages.
