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.NavigateUrl = urlString;
windowManager.Windows.Title = name;
windowManager.Windows.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?
