public ActionResult ReportSample(tbbooking tbbook)
        {
            var uemail = Convert.ToString(Session["uemail"]);
            var bookingid = tbbook.bookingid;
            var getticket = db.tbbookings.Where(a => a.bookingid == tbbook.bookingid).ToList();
            return new RazorPDF.PdfResult(getticket, "ReportSample");

            //var sb = new System.Text.StringBuilder();
            //TextWriter tw = new System.IO.StringWriter(sb);
            //myResult.View.Render(getticket, tw);
            //var resultCache = sb.ToString();
            //XmlParser parser;
            //using (var reader = GetXmlReader(resultCache))
            //{
            //    while (reader.Read() && reader.NodeType != XmlNodeType.Element)
            //    {
            //        // no-op
            //    }

            //    if (reader.NodeType == XmlNodeType.Element && reader.Name == "itext")
            //        parser = new XmlParser();
            //    else
            //        parser = new HtmlParser();
            //}

            //// Create a document processing context
            //var document = new Document();
            //document.Open();

            //// Associate output with response stream
            //var pdfWriter = PdfWriter.GetInstance(document, viewContext.HttpContext.Response.OutputStream);
            //pdfWriter.CloseStream = false;

            //// Create the pdf file in the directory system
            //var fileStream = new FileStream("~/Content/pdf", FileMode.Create);
            //var pdfWriter2 = PdfWriter.GetInstance(document, fileStream);

            //// this is as close as we can get to being "success" before writing output
            //// so set the content type now
            //viewContext.HttpContext.Response.ContentType = "application/pdf";

            //// parse memory through document into output
            //using (var reader = GetXmlReader(resultCache))
            //{
            //    parser.Go(document, reader);
            //}

            //fileStream.Close();
            //pdfWriter.Close();
            //pdfWriter2.Close();
        }
