    I'm using telerik Controls, I'm getting this error on vs2010 debugger on any ajax request (if I publish the webapplication to my web server it works normaly)

    JavaScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

    Hi Wissam,

    This particular error is not specific to Telerik RadControls for ASP.NET AJAX. If you've used the Microsoft ASP.NET AJAX UpdatePanel control, there's a good chance you've hit the "Sys.WebForms.PageRequestManagerParserErrorException" error. Please have a look at this article to know more about such an error and how it can be avoided in your application.
