printing from within an ajax panel causes javascript error

[Jonathan]

Hello,

I have a radrid with one column setup for printing the object associated with the ID of the row.  Works great unless I ajaxify the grid either wrapping with an AJAX panel or using an ajax manager on the page then I get a javascript error on postback wchihc makes sense because the ajax manager or panel will be trying to interpret the response.  How to I bypass the ajax panel for this one behaviour and have the browser rather than the ajax manager respond to the new contect header information?

protected void radGridAll_ItemCommand(Object sender, GridCommandEventArgs e)
        {
            if (e.CommandName != "Print" ) return;

            Guid id = Guid.Parse(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["ID"].ToString());

            //lblMessage.Text = string.Empty;

            switch (e.CommandName)
            {

                case "Print":

                    //string args = Request.QueryString["ApplicationID"];

                    NMotionServer.ApplicationLead _application = NMotionServer.ApplicationLeadService.GetByID(id);

                    if (_application.LeadStatusID == (int)enumLeadStatus.Fresh || _application.LeadStatusID == (int)enumLeadStatus.Viewed)
                    {
                        AppHistory _leadStatusEvent = new AppHistory() { ApplicationLeadID = _application.ID, EventTypeID = 2, ForeignKeyID = (int)enumLeadStatus.Printed, Timestamp = DateTime.Now, UserProfileID = ((UserProfile)Session["_userProfile"]).ID };
                        AppHistoryService.Save(_leadStatusEvent);
                        _application.LeadStatusID = (int)enumLeadStatus.Printed;
                        ApplicationLeadService.Save(_application);
                    }

                    //RptApplication _applicationReport = new RptApplication((DealerLinkServer.SalesForceWebReference.SforceService)Session["SalesForceBinding"], args);

                    RptApplication _applicationReport = new RptApplication(id.ToString());
                    ReportProcessor _processor = new ReportProcessor();
                    RenderingResult result = _processor.RenderReport("PDF", _applicationReport, null);
                    string fileName = "NMotion_Lead_" + _application.ApplicantNameLast2First.Replace(" ", "_").Replace(",","_").Replace("'", "_") + "_" + _application.DateOfApplication.Year + _application.DateOfApplication.Month + _application.DateOfApplication.Day + ".pdf";

                    Response.Clear();
                    Response.ContentType = result.MimeType;
                    Response.Cache.SetCacheability(HttpCacheability.Private);
                    Response.Expires = -1;
                    Response.Buffer = true;

                    Response.AddHeader("Content-Disposition", string.Format("{0};FileName=\"{1}\"", "attachment", fileName));
                    Response.BinaryWrite(result.DocumentBytes);
                    Response.End();

                    break;
            }
        }

Thanks

Hi Jonathan,

Editing the Response Headers with ajax request is not supported. Your application need to fully reload the page in order for your scenario to work.

All the best,
