Response.Redirect not working

[Andy]

My ASP.NET application uses RADScriptManager and multiple RADAJAXPanels.

Response.Redirect's called in code behind executed via callbacks originating inside the RADAjaxPanels do not work and the following Javascript error is generated on the source page.

Also, probably related to this, the customerrors page does not get rendered in when runtime exceptions occur in code-behind. I assume it's due to the same problem that redirects are not working.

Thanks

Javascript error:

Line:

605

Char: 13

Error:Sys.WebForms.PageRequestManagerServerErrorException: An

unknown error occurred while processing the request on the server. The

status code returned from the server was: 0

Code: 0

The errors.aspx page does get called (debugger stopped on breakpoint on page load) but it looks like the html is streamed back to the calling page but is intercepted by the AJAX framework  and 

Sys.WebForms.PageRequestManagerParserErrorException throws an exception trying to parse the resulting html page.

Follow-up:   When I explicitly force a httpcontext.current.reponse.Redirect(...) in my code-behind event handler called from within the RADAjaxPanel the target page is being called but the rendered page is coming back to the browser and the AJAX framework is throwing a runtime exception.

I added my own AJAX event handler in my source page containing the RADAjaxPanels and the _xmlHttpRequest.ResonseText contains the HTML rendered from the aspx page targeted by the resonse.redirect call.

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

function EndRequestHandler(sender, args)
{ 
    if (args.get_error() != undefined) 
    { 
        var errorMessage = args.get_error().message; 
        args.set_errorHandled(true); 
        alert(args._response._xmlHttpRequest.responseText);
    }
}

Hello A,

This is a known problem of the ASP.NET AJAX framework on which our ajax controls are based on. More info on the problem and solution are available here:
