      {
          const string attachment = "attachment; filename= grdDetail.pdf";

          Response.AddHeader("content-disposition", attachment);
          Response.ContentType = "application/pdf";
          Response.Cache.SetCacheability(HttpCacheability.NoCache);
          Response.ClearContent();

          StringWriter sw = new StringWriter();
          HtmlTextWriter htw = new HtmlTextWriter(sw);

          studentReportGrid.RenderControl(htw);

          StringReader sr = new StringReader(sw.ToString());

          Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);

          HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
