            Response.ContentType = "Application/pdf";
            Response.Cache.SetCacheability(HttpCacheability.Private); // set as private for HTTPS dowload issue with IE
            Response.AppendHeader("Content-Disposition", "attachment;filename=Classes_" + cmbsubcategory.SelectedValue.ToString() + "_" + cmbstatus.SelectedItem.ToString() + "_" + DateTime.Now.ToString() + ".pdf");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);

            gridbind(cmbsubcategory.SelectedValue.ToString(), cmbstatus.SelectedValue.ToString());
            GridView1.AllowPaging = false;

            GridView1.DataBind();
            GridView1.RenderControl(hw);

            StringReader sr = new StringReader(sw.ToString());
            Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
            HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
            PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
            pdfDoc.Open();
            Paragraph footer = new Paragraph("Category:Class | Subcategory:" + cmbsubcategory.SelectedValue.ToString() + "| Status:" + cmbstatus.SelectedItem.ToString() + "| " + DateTime.Now.ToShortDateString(), FontFactory.GetFont(FontFactory.COURIER, 14, iTextSharp.text.Font.NORMAL, new Color(0, 163, 217)));
            footer.Alignment = Element.ALIGN_RIGHT;
            PdfPTable footerTbl = new PdfPTable(1);
            footerTbl.TotalWidth = 300;
            footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;

            string imageFilePath = GetUrl("header.jpg");

            iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);

            jpg.Alignment = Element.ALIGN_CENTER;



            PdfPCell cell = new PdfPCell(footer);
            pdfDoc.Add(jpg);
            pdfDoc.Add(footer);


            htmlparser.Parse(sr);
            pdfDoc.Close();
            Response.Write(pdfDoc);
            Response.End();
}
