Hi,

I'm working with telerik grid, combobox and radpanels. All these panels are in separet ascx files and each one has a RadAjaxPanel that make is to behave in ajax style.

I got a modal window that opens form the grid (when clicking on the appropriate column button). The modal window has a Close Button and a Save to Cart button. When the  close button us clicked  I do the following to refresh the parent page -         oWindow.BrowserWindow.SubmitPage();       

And, sometimes (not always) this makes the browser to show the follwoing error.
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0

Could you please advice what's wrong and how to work it out?

Many thanks,
Nicolae

Although I am not sure what can be the exact cause for the error to be generated, I found some very useful tips from this public help topic on telerik.com. They can help you track down the reason for the erroneous behavior on your end.
