Closing Telerik Window on exception

[iggy]

If an unhandled exception occurs within the page that's loaded in the Telerik Window, how would we close the window and show the unhandled exception in the main page?

I understand that I can inject the javascript to close the window from the server side, but If I inject the script on the OnError handler on the page, the page never completes rendering and the javascript for closing the window never fires.

PS: Currently, we are using the Application_Error in Global.asax.cs to handle unhandled exceptions.

Hello,


How about using RegisterStartupScript() server method to invoke the client method to close window?

More information on invoking the client function will be available in the KB Article.

That's exactly how I am trying to do it.

The issue is that the page never gets rendered completely (due to the exception) for the script registered using RegisterStartupScript() to be executed.

To duplicate this issue, override OnError

		protected override void OnError(EventArgs e)
		{
			string s  = "<script language='javascript' type='text/javascript'>Sys.Application.add_load(CloseWin);</script>";
			Page.ClientScript.RegisterStartupScript(typeof(Page), "Close", s);
		}

and simulate an exception by doing a throw new ApplicationException() in Page_Load method

CloseWin is a JS function that does a:

GetRadWindow().close();

Hi Iggy,

This is a general ASP.NET knowledge related to executing a script from the server-side.

We generally do not support custom solutions, but as an exception we have created a sample page that illustrates the approach. You can find it attached. 

Note that this is highly dependant on the postbacks and the same-domain JavaScript policy.
