Incidentally, there is a rather amusing message when you look at the source code of the error page

public static void CreateMessageAlert(System.Web.UI.Page senderpage, string alertMsg)
  {
      string alertKey = "alertKey";
      string strScript;
      strScript = "<script language=JavaScript>alert('" + alertMsg + "')</script>";
      if (!senderpage.IsStartupScriptRegistered(alertKey))
      {
          senderpage.RegisterStartupScript(alertKey, strScript);
      }
  }

  public static void AlertOnAjaxPage(System.Web.UI.Page SenderPageName, string PanelName, string Message)
  {
      System.Web.UI.UpdatePanel u = (UpdatePanel)((ContentPlaceHolder)((MasterPage)SenderPageName.Master).FindControl("ContentPlaceHolder1")).FindControl(PanelName);
      System.Web.UI.ScriptManager.RegisterClientScriptBlock(u, u.GetType(), "Alert", "alert('" + Message + "') ", true);
