  itextsharp document has no pages

  Mar 18, 2012 02:25 AM|sparrow37|LINK

  
  I am trying to generate pdf of my gridview using following code:

  HtmlForm form = new HtmlForm(); form.Controls.Add(PGGridViewDetail); StringWriter sw = new StringWriter(); HtmlTextWriter hTextWriter = new HtmlTextWriter(sw); form.Controls[0].RenderControl(hTextWriter); string htmlContent = sw.ToString();

  htmlContent = Regex.Replace(htmlContent, "</?(a|A).*?>", "");
  htmlContent = Regex.Replace(htmlContent, "px", "");

  Document document = new Document();

  
  // step 2:
  // we create a writer that listens to the document
  // and directs a PDF-stream to a file

  string Path = Server.MapPath("~/Jaram PDF/PDFS/") + "Sample.pdf";

  PdfWriter.GetInstance(document, new FileStream(Path, FileMode.Create));

  // step 3: we open the document
  document.Open();

  // step 4: we add a paragraph to the document
  document.Add(new Paragraph(htmlContent.ToString()));

  System.Xml.XmlTextReader _xmlr = new System.Xml.XmlTextReader(new StringReader(htmlContent));

  
  _xmlr.WhitespaceHandling = WhitespaceHandling.None;

  ITextHandler xmlHandler = new ITextHandler(document);
  xmlHandler.Parse(_xmlr);

  
  //HtmlParser.Parse(document, _xmlr);

  // step 5: we close the document
  document.Close();

  but is is showing the html markup of the grid instead of grid in newly generated pdf.

  if I comment step 4

  // step 4: we add a paragraph to the document document.Add(new Paragraph(htmlContent.ToString()));

  then I get document has no pages.

  please suggest me solution

  I had this problem too, try removing 

  // step 5: we close the document 
  document.Close();

  And see if this works for you...

  use this:

   HtmlForm form = new HtmlForm(); form.Controls.Add(PGGridViewDetail);
              StringWriter sw = new StringWriter();
              HtmlTextWriter hTextWriter = new HtmlTextWriter(sw);
              form.Controls[0].RenderControl(hTextWriter);
              string htmlContent = sw.ToString();
  
  
              htmlContent = Regex.Replace(htmlContent, "</?(a|A).*?>", "");
              htmlContent = Regex.Replace(htmlContent, "px", "");
              TextReader reader = new StringReader(htmlContent);
  
              Document document = new Document();
  
              string Path = Server.MapPath("~/Jaram PDF/PDFS/") + "Sample.pdf";
  
              PdfWriter.GetInstance(document, new FileStream(Path, FileMode.Create));
  
              // step 3: we open the document
              document.Open();
  
              // step 4: we add a paragraph to the document
              document.Add(new Paragraph(htmlContent.ToString()));
  
              HTMLWorker worker = new HTMLWorker(document);
  
              document.Open();
  
              // step 5: parse the html into the document
              worker.Parse(reader);
  
              worker.Close();
              document.Close();
