               string docname = "";
               string room = "";
               SqlDataReader dr = objcon.GetReader("select IN028_01_01.IN028_70,IN013_02,IN028_03,IN013_25 FROM IN028_01_01 INNER JOIN IN028 ON IN028.IN028_01=IN028_01_01.IN028_01 INNER JOIN IN013 ON IN013.IN013_01=IN028.IN013_01  where IN028.IN028_01='" + cnscid + "'");

               }
               objcon.dr.Close();
               string Fortunelogo = Server.MapPath("..//Images//printlogo.png");

               string pdfheader = Server.MapPath("..//Images//printname.png");
               var document = new Document(PageSize.A4, 50, 30, 20, 20);

               var output = new MemoryStream();
               var writer = PdfWriter.GetInstance(document, output);
               document.Open();

               var titleFont = FontFactory.GetFont("Tahoma", 24, Font.BOLDITALIC, new Color(125, 88, 15));

               var itemsTable = @"<table border=0 cellpadding=3 cellspacing=3 >";
               itemsTable += string.Format("<font style=\"font-family:Tahoma;border-collapse:separate;border-spacing: 0 1em;\">");
               itemsTable += string.Format("<tr><td align=\"center\"  style=\"color:#000000;\"><table border=\"0\"><tr><td  align=\"Left\" colspan=\"2\"><img src='" + Fortunelogo + "' height=\"5px\" width=\"5px\" style=border-style: none></td></tr><tr><td colspan=\"20\" align=\"left\" style=\"color:#000000;margin:100px;\"  font-size=\"24px\" Valign=\"middle\">"Left\"" colspan="\"20\""> Date :" + DateTime.Now.ToString("dd/MMM/yyyy") + " </td></tr><tr><td align=\"Left\" colspan=\"20\" style=\"color:#000000;border:solid;\" >Token No: ^__b style=""color: #000000; border: solid; font-size: xx-large">" + tokenno + "</td></tr><tr><td align=\"Left\" colspan=\"20\" style=\"color:#000000;border:solid;\" >Room No : ^__b style=""color: #000000; border: solid; font-size: xx-large">" + room + "</td></tr><tr><td align=\"Left\" colspan=\"20\" style=\"color:#000000;border:solid;\" >Please be seated .You will be served shortly.</td></tr>");

               itemsTable += string.Format("</table></td></tr></font></table>");
                ArrayList htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(itemsTable), null);
               for (int k = 0; k < htmlarraylist.Count; k++)
               {
                   document.Add((IElement)htmlarraylist[k]);
