  HTML to PDF using itextsharp HtmlParser

  Sep 05, 2013 06:39 PM|2bitcoder|LINK

  Hello,

  I have html pages that are designed specifically for printing (Reports), they work well and look good.

  I would like to be able to output these to pdf also, I've previously tried with print drivers, however the results are varied and not easy for users.

  Hence, I would like to be able to output the page directly to pdf using itextsharp and the htmlparser. I've been looking at http://www.mikesdotnetting.com/Article/205/Exporting-The-Razor-WebGrid-To-PDF-Using-iTextSharp and itextsharp articals, which I intend on using to write other reports.

  I've also looked at this http://aspnettutorialonline.blogspot.com/2012/04/converting-html-to-pdf-using-itextsharp.html however I'm really not comfortable with c# yet, and would much prefer the razor approach.

  I would prefer not to have to re-code my html print optimsed pages if I could easily use the htmlparser,  which I'm not sure how to implement.

  Any tips would be helpful...

            string strHtml = string.Empty;
            //HTML File path -http://aspnettutorialonline.blogspot.com/
            string htmlFileName = Server.MapPath("~") + "\\files\\" + "ConvertHTMLToPDF.htm";
            //pdf file path. -http://aspnettutorialonline.blogspot.com/

            //reading html code from html file
            FileStream fsHTMLDocument = new FileStream(htmlFileName, FileMode.Open, FileAccess.Read);
            StreamReader srHTMLDocument = new StreamReader(fsHTMLDocument);
           strHtml = srHTMLDocument.ReadToEnd();
           srHTMLDocument.Close();
           strHtml = strHtml.Replace("\r\n", "");
          strHtml = strHtml.Replace("\0", "");
           CreatePDFFromHTMLFile(strHtml, pdfFileName);
  
         Response.Write("pdf creation successfully with password -http://aspnettutorialonline.blogspot.com/");
  
        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }
    }
    public void CreatePDFFromHTMLFile(string HtmlStream, string FileName)
    {
        try
        {
            object TargetFile = FileName;
            string ModifiedFileName = string.Empty;
            string FinalFileName = string.Empty;
          /* To add a Password to PDF -http://aspnettutorialonline.blogspot.com/ */
            TestPDF.HtmlToPdfBuilder builder = new TestPDF.HtmlToPdfBuilder(iTextSharp.text.PageSize.A4);
            TestPDF.HtmlPdfPage first = builder.AddPage();
           first.AppendHtml(HtmlStream);
            byte[] file = builder.RenderPdf();
            File.WriteAllBytes(TargetFile.ToString(), file);
            iTextSharp.text.pdf.PdfReader reader = new iTextSharp.text.pdf.PdfReader(TargetFile.ToString());
            ModifiedFileName = TargetFile.ToString();
            ModifiedFileName = ModifiedFileName.Insert(ModifiedFileName.Length - 4, "1");
            string password = "password";
            iTextSharp.text.pdf.PdfEncryptor.Encrypt(reader, new FileStream(ModifiedFileName, FileMode.Append), iTextSharp.text.pdf.PdfWriter.STRENGTH128BITS, password, "", iTextSharp.text.pdf.PdfWriter.AllowPrinting);
            //http://aspnettutorialonline.blogspot.com/
            reader.Close();
           if (File.Exists(TargetFile.ToString()))
                File.Delete(TargetFile.ToString());
            FinalFileName = ModifiedFileName.Remove(ModifiedFileName.Length - 5, 1);
            File.Copy(ModifiedFileName, FinalFileName);
            if (File.Exists(ModifiedFileName))
                File.Delete(ModifiedFileName);
       }

  Follow up - I implemented the above solution, however I got errors as I think, my .CSHTML may have been to complex for the htmlparser, simplified html worked fine.

  In the end I spent a day learning iTextSharp, then wrote my reports.

  The outcome was better than I'd hoped.
