                string pdfFileName = Request.PhysicalApplicationPath + "\\files\\" + "GenerateHTMLTOPDF.pdf";
                StringWriter sw = new StringWriter();
                HtmlTextWriter hw = new HtmlTextWriter(sw);
                dvHtml.RenderControl(hw);
                StringReader sr = new StringReader(sw.ToString());
                strHtml = sr.ReadToEnd();
                sr.Close();
                CreatePDFFromHTMLFile("<pre><div style='font - family: arial unicode ms; '>" + strHtml + "</div>

", pdfFileName);
Response.ContentType = "application/x-download";
Response.AddHeader("Content-Disposition", string.Format("attachment; filename=\"{0}\"", "GenerateHTMLTOPDF.pdf"));
Response.ContentEncoding = Encoding.UTF8;
Response.WriteFile(pdfFileName);
Response.HeaderEncoding = Encoding.UTF8;
Response.Flush();
Response.End();
}
catch (Exception ex)

       private void CreatePDFFromHTMLFile(string html, string FileName)
       {
           TextReader reader = new StringReader(html);
           // step 1: creation of a document-object
           Document document = new Document(PageSize.A4, 30, 30, 30, 30);
           // step 2:
           // we create a writer that listens to the document
           // and directs a XML-stream to a file
           PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(FileName, FileMode.Create));
           // step 3: we create a worker parse the document
           HTMLWorker worker = new HTMLWorker(document);
           // step 4: we open document and start the worker on the document
           document.Open();
           // step 4.1: register a unicode font and assign it an allias
           //FontFactory.Register("C:\\Windows\\Fonts\\ARIALUNI.TTF", "arial unicode ms");
           string fontPath = Server.MapPath("~/fonts/");
           BaseFont bf = BaseFont.CreateFont(fontPath + "ARIALUNI.ttf", BaseFont.IDENTITY_H, true);
           // step 4.2: create a style sheet and set the encoding to Identity-H
           iTextSharp.text.html.simpleparser.StyleSheet ST = new iTextSharp.text.html.simpleparser.StyleSheet();
           ST.LoadTagStyle("body", "encoding", "Identity-H");
           // step 4.3: assign the style sheet to the html parser
           worker.SetStyleSheet(ST);
           worker.StartDocument();
           // step 5: parse the html into the document
           worker.Parse(reader);
           // step 6: close the document and the worker
           worker.EndDocument();
           worker.Close();
           document.Close();
       }
