    Hi,

    I am using RadGrid and it was working fine, but from yesterday I am getting an error like this "Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server." I am getting this when I expand to see the child grid and afterwards when I am contracting that. I ahd put EnablePartialrendering=true on script manager. I tried with setting false also but then I am getting this same error on load of grid itself. Can any one help??

    Hi Jincy,

    I found two forum links which discuss a similar error. Probably, you can find some clue in these.
    PageRequestManagerServerErrorException on Grouping
    SelectedIndexChanged not firing +error

    I am having a similar problem with RadAjax and RadScriptManager and the 3.5 ReportViewer control.  

    Setting 
        RadScriptManager1.EnablePartialRendering =
    false;

    results in: 

    Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object


    setting it to true regardles of wethere the ajax panel is enabled results in:

    Microsoft JScript runtime error: 'this._postBackSettings.async' is null or not an object



    I have the latest telerik.

    Thanks

    Hello Martin,

    Can you please check whether the second error appear if you set EnableAJAX = false for your RadAjaxPanel (wrapping the ReportViewer control) or replace it with standard MS UpdatePanel instance? If the problem persists, I suppose that the ReportViewer is somehow not compatible with the ASP.NET AJAX framework and you will need to find a method to bypass the limitation searching in the ASP.NET AJAX forums.

    Once you make the configuration fully operational, re-enable the ajax for the RadAjaxPanel and you should be done.

    Kind regards,

    I am getting the same error when I simply added the script manager to my form:

    Microsoft JScript runtime error: 'Sys.WebForms.PageRequestManager' is null or not an object

    If I find a solution I will post it here.
