I have been upgrading an appication from Asp.Net to Asp.Net Ajax. But I'm having trouble making the ajax part working.
All I get is this error:
"Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled."
As soon as I add a Ajaxsetting programatically or through html I get the same error.
I have been stuck on this error some while now. I have browsed the forum for help, but cant seem to find a solution to my problem.
Adding a simple page that produces this error
