  Using iTextSharp to convert current webpage to PDF

  Mar 24, 2012 07:11 PM|LINK

  Hi there,

  I am trying to return the current webpage as a PDF on button click. When the user clicks the button I want the PDF to appear so the user can then save it. I have the following code so far:

  <%@ Control Language="C#" AutoEventWireup="true" %>
  <%@ Import Namespace="System" %>
  <%@ Import Namespace="System.Collections.Generic" %>
  <%@ Import Namespace="System.Linq" %>
  <%@ Import Namespace="System.Web" %>
  <%@ Import Namespace="System.Web.UI" %>
  <%@ Import Namespace="System.Web.UI.WebControls" %>
  <%@ Import Namespace="System.IO" %>
  <%@ Import Namespace="System.Text.RegularExpressions" %>
  <%@ Import Namespace="iTextSharp.text" %>
  <%@ Import Namespace="iTextSharp.text.pdf" %>
  <%@ Import Namespace="iTextSharp.text.html" %>
  <%@ Import Namespace="iTextSharp.text.xml" %>
  <%@ Import Namespace="System.Xml" %>
  <%@ Import Namespace="iTextSharp.text.html.simpleparser" %>
  
  <script runat="server">
  
      public void CreatePDFDocument(string strHtml)
      {
          string strFileName = HttpContext.Current.Server.MapPath("test.pdf");
          
          //Creation of a document-object
          Document document = new Document();
          
          //We create a writer that listens to the document
          PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
          StringReader se = new StringReader(strHtml);
          HTMLWorker obj = new HTMLWorker(document);
          document.Open();
          obj.Parse(se);
          document.Close();
      }
      
      private void buttonPDF_Click(object sender, System.EventArgs e)
      {
          CreatePDFDocument("hello.pdf");
      }
  </script>
  
  <asp:Button runat="server" ID="buttonPDF" OnClick="buttonPDF_Click" CssClass="button" Text="PDF"></asp:Button>

  But when I click I get nothing...

  Firstly, do I need to create a pdf file called test.pdf locally? I'm just not sure about how to get this working?

  When I click the button it does call the method but it doesn't do anything, my problem is that I need to return the pdf to the page.

  Can someone please help?

  Regards,

  There might be some link which is not found.

  Parser is  trying to embed inside the page.
