RadWindowManager and RadAjaxPanel

[Emmet]

I have a control which has a number of buttons in an AjaxPanel to prevent unnecessary refreshs. Also on the control is a RadWindowManager with one window. When i click on 2 of the buttons I run the following function

    private void ShowDocWindow(string urlString, string name)
    {
        windowManager.Windows[0].NavigateUrl = urlString;
        windowManager.Windows[0].Title = name;
        windowManager.Windows[0].VisibleOnPageLoad = true;
   }

This displays a different window depending on the button pressed. When I do this I get an intermittent bug, it only happens when I click on one of these 2 buttons.

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 2007.'.
 
It occurs before the window displays and prevents the window from displaying. After it occurs the page is still available and if I click on the button again it works. It occurs maybe one in every 10 or 20 tries.

Any ideas why it might be occuring?

Thanks

Hi Emmet,

Are you using VS2008 Beta? We've received a report for such an error with VS2008 Beta, however we were not able to reproduce it locally.

If you can reproduce the problem, can you please open a new support ticket and send us a small sample project where it can be observed? We will check it right away and do our best to help.



All the best,

Are you using the trial/developer version of the dll? I used to get that error as well when i was using the developer. I believe it is the actual trial reminder message that is somehome being returned/parsed by the page and hence the error

You know i was thinking that it was occuring at about the same frequency as those trial messages. That's probably it. I'll see if I can speed up our purchase of the full version.

Thanks
