    I set timer to referesh RadGrid.  On the page also has RadAjaxManager  and RadAjaxLoadPanel.  After few reloadings occured, then I get the error message below. 

    May I have a clue? 

    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 2009.'.

    Hello Duy ,

    This is a generic ASP.NET AJAX framework error. Please take a look at the following article that elaborates on the matter.

    I also have this error sometimes with the trial version of the telerik controls.
    It seems as if from time to time the "trial message" is emitted which works fine with page requests, but of course changes the expected ajax return.
    So if you use the trial controls I would suggest to first use the release - maybe the error disappears.
    I you use release - forget what I wrote :)
