If i run this code i got an error i.e,

A page can have only one server-side Form tag.

Does this happen on: this.Page.RenderControl(hw);
If it does then try adding the following in your code behind:

public override void VerifyRenderingInServerForm(Control control) { }

If the problem remains then additionally add the following in your page's source:

<%@ Page ... EnableEventValidation="false" %>

If the issue does not lie in RenderControl method then try another approach, for example try this C# conversion of HTML web page to a PDF file.

You can convert the web page content into PDF using iTextSharp library. Download ITextsharp and add its reference to your project. ITextsharp is a free HTML to PDF Library at http://sourceforge.net/projects/itextsharp/[^]

C#

using System.IO;
using iTextSharp.text;
using iTextSharp.text.html.simpleparser;
using iTextSharp.text.pdf;
......
protected void btnExport_Click(object sender, EventArgs e)
{
    Response.ContentType = "application/pdf";
    Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    StringWriter sw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(sw);
    this.Page.RenderControl(hw);
    StringReader sr = new StringReader(sw.ToString());
    Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
    pdfDoc.Open();
    htmlparser.Parse(sr);
    pdfDoc.Close();
    Response.Write(pdfDoc);
}
