  2nd Example

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html;
using System.IO;
using System.Collections;
using System.Net;
 
Now in Click event of button i m creating a new 
HtmlForm and adding the gridview control to this form in code behind , 
than creating instance of StringWriter class and HtmlTextWriter to write strings and than rendernig these to form created earlier
  

protected void btnExport_Click(object sender, EventArgs e)
{
HtmlForm form = new HtmlForm();
form.Controls.Add(GridView1);
StringWriter sw = new StringWriter();
HtmlTextWriter hTextWriter = new HtmlTextWriter(sw);
form.Controls[0].RenderControl(hTextWriter);
string html = sw.ToString();
Document Doc = new Document();

//PdfWriter.GetInstance
//(Doc, new FileStream(Request.PhysicalApplicationPath 
//+ "\\AmitJain.pdf", FileMode.Create));

PdfWriter.GetInstance
(Doc, new FileStream(Environment.GetFolderPath
(Environment.SpecialFolder.Desktop)
+ "\\AmitJain.pdf", FileMode.Create));
Doc.Open();

Chunk c = new Chunk
("Export GridView to PDF Using iTextSharp \n",
FontFactory.GetFont("Verdana", 15));
Paragraph p = new Paragraph();
p.Alignment = Element.ALIGN_CENTER;
p.Add(c);
Chunk chunk1 = new Chunk
("By Amit Jain, amit_jain_online@yahoo.com \n",
FontFactory.GetFont("Verdana", 8));
Paragraph p1 = new Paragraph();
p1.Alignment = Element.ALIGN_RIGHT;
p1.Add(chunk1);

Doc.Add(p);
Doc.Add(p1);

System.Xml.XmlTextReader xmlReader =
new System.Xml.XmlTextReader(new StringReader(html));
HtmlParser.Parse(Doc, xmlReader);

Doc.Close();
string Path = Environment.GetFolderPath
(Environment.SpecialFolder.Desktop)
+ "\\AmitJain.pdf";

ShowPdf(Path);
}

private void ShowPdf(string strS)
{
Response.ClearContent();
Response.ClearHeaders();

("Content-Disposition","attachment; filename=" + strS);
Response.TransmitFile(strS);
Response.End();
