Event Receiver Cancel and RedirectUrl code not working

Hi All,

I am trying to update SharePoint 2010 event receiver code for a list. The problem is the old way to redirect the user to a custom error page is now obsolete and no longer works. I have tried to find example of SharePoint 2013 code that does the exact thing without any luck. The old obsolete SharePoint 2010 code is shown below

      ///<summary>

      /// A list is being deleted.

      ///</summary>

      publicoverridevoid ListDeleting(SPListEventProperties properties)

       {

           var web = properties.WebUrl;

         // properties.ErrorMessage = "Custom Error Message";

            properties.Status =SPEventReceiverStatus.CancelWithRedirectUrl;

            properties.RedirectUrl = web +"/_layouts/Seal/CustomErrorPage.aspx";

        }

    }

}

Does anyone have SharePoint 2013 code that does the same thing or something similar or a link to a web site that demonstrates how to do it for a SharePoint 2013 site?

I hope you can helpColin
