If you want to create non editable PDF, you may encrypt the PDF by setting owner password and user password,owner password have all the right to edit the PDF file, while user password has to subject to the restrictions set by owner password, please see the code in this project:

Hi ALOK,

Please try this in your .cs file...

  Response.ContentType = "application/pdf";
          Response.AddHeader("content-disposition", "attachment;filename= " + Session["UserName"] + "_ProjectReport.pdf");
          Response.Cache.SetCacheability(HttpCacheability.NoCache);
          StringWriter sw = new StringWriter();
          sw.WriteLine("<table align=center><tr><td>" + dgDgrid.Caption + "</td></tr></table>");
          sw.WriteLine("<br /><br />");
          HtmlTextWriter hw = new HtmlTextWriter(sw);
          dgDgrid.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();
          pdfDoc.AddHeader("Head", "Project Report");
          //iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(HttpContext.Current.Request.PhysicalApplicationPath + "Images\\Logo.png");
          //pdfDoc.Add(img);
          htmlparser.Parse(sr);
          pdfDoc.Close();
          Response.Write(pdfDoc);
          Response.End();


where dgDgrid is your dataset....
