    Occasionally, I got the same message 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.

    Details: Error Parsing near 'Telerik.Web.UI.2008.'.
    I thought it only happened on Telerik 2007 version. Are you sure it caused by my version is still a trial version one or something else ?

    John-

    Sorry to see you're having trouble. Is this message part of another conversation? It looks like you were continuing a thought, so please let me know if there is another thread that describes your problem in more detail.

    That aside, it's hard to say what's causing this problem without seeing some code. Can you please open a support ticket and provide a sample app the recreates this problem or post some sample of your code here to the forums? That will help us quickly see what's going on and try to provide you with a solution. In general, your trial version should not be causing an error like this, so there is probably an issue with some other code on your page.

    Hope to help more-
