Hello sadiqabbas,

There are some methods and properties which work in non-ajax scenarios but cannot work with AJAX and this is related to general MS AJAX knowledge and it is not directly related to RadControls. The Response.Write method is one of those methods - if you disable ajax and use a plain postback instead you will see that the problem will disappear. You can find those methods in the MSDN listed below, in the section "Properties and Methods not Supported During Asynchronous Postbacks":

http://msdn.microsoft.com/en-us/library/bb386454.aspx

In order to execute teh script from the server in your case by using AJAX, you should use the approaches explained in the following blogpost and KB article:

Let us know if you need further assistance.
