I currently have a webpage that Inherits from a basePage class. Within the basePage class, I have some code to register an event handler for all unhandled errors on the web page, as seen below :

  protected override void OnInit(EventArgs e){
      // Trap any unhandled exceptions and log them.
      Error += BasePage_Error;
      base.OnInit(e);
    }

  private void BasePage_Error(object sender, EventArgs e){
      Exception ex = Server.GetLastError();
      int errorID = LogException(ex);
      Server.ClearError();
      Response.Redirect(Page.ResolveUrl(string.Format("~/Error.aspx?ReferenceNumber={0}", errorID)));
    }


The problem comes in after I add in an RadAjax panel to the main page and surround my current form with the AjaxPanel. If some unhandled error ends up going to BasePage_Error routine, when it goes to the Response.Redirect line I get the following javascript error on the browser:

Line: 4723
Error: Sys.WebForms.PageRequestManagerServerErrorException: Input string was not in a correct format.

The Response.Redirect command is somehow causing issues, but only when I have the AjaxPanel on the page. If I remove the panel, and run into the same issue, the Response.Redirect line works perfectly. Does anyone have an idea on what I can be doing wrong, or how to fix this issue?

Hello Kevin,

Can you reproduce this error using standard ASP.NET UpdatePanel or it happens with our controls only? If this is not the case, could you please attach a sample project so we can debug your application locally?

I was able to resolve this issue, by registering for the onAsyncPostBackError event on the scriptmanager and capturing and redirecting from that routine.
