Hi,
Firstly I would like to thank you for your quick answer.
When I start to debug, just under my project solution is created a file called "Script Documents" and under it "Internet Explorer". (script documents/internet explorer/default.aspx/scriptresource.axd?d=...)
Hope it is clear.
(By the way I dont get the same exception in firefox)
Thanx in advance.
hatice, as far as I know scriptresource.axd is httphandler of the ASP.NET AJAX frameword and is not connected to Telerik RadControls. You may repost your question in the ASP.NET AJAX forums.
