title: Render User Controls and call their Page_Load
body: <p>The following code will not work because the controls (page1, page2, page3) require that their "Page_Load" event gets called.</p>
  
  <pre><code>using System;
  using System.IO;
  using System.Web;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using iTextSharp.text;
  using iTextSharp.text.html.simpleparser;
  using iTextSharp.text.pdf;
  
  public partial class utilities_getPDF : System.Web.UI.Page
  {
      protected void Page_Load(object sender, EventArgs e)
      {
          // add user controls to the page
          AddContentControl("controls/page1");
          AddContentControl("controls/page2");
          AddContentControl("controls/page3");
  
          // set up the response to download the rendered PDF...
          Response.ContentType = "application/pdf";
          Response.ContentEncoding = System.Text.Encoding.UTF8;
          Response.AddHeader("Content-Disposition", "attachment;filename=FileName.pdf");
          Response.Cache.SetCacheability(HttpCacheability.NoCache);
  
          // get the rendered HTML of the page
          System.IO.StringWriter stringWrite = new StringWriter();
          System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
          this.Render(htmlWrite);
          StringReader reader = new StringReader(stringWrite.ToString());
  
          // write the PDF to the OutputStream...
          Document doc = new Document(PageSize.A4);
          HTMLWorker parser = new HTMLWorker(doc);
          PdfWriter.GetInstance(doc, Response.OutputStream);
          doc.Open();
          parser.Parse(reader);
          doc.Close();
  
      }
      //  the parts are probably irrelevant to the question...
      private const string contentPage = "~/includes/{0}.ascx";
      private void AddContentControl(string page)
      {
          content.Controls.Add(myLoadControl(page));
      }
      private Control myLoadControl(string page)
      {
          return TemplateControl.LoadControl(string.Format(contentPage, page));
      }
  }
  </code></pre>
  
  <p>So my question is:</p>
  
  <p><strong>How can I get the controls HTML?</strong></p>
