Export asp.net page to pdf issue

Question

To export a page to Pdf I found code from google. After exporting I am getting the additional info into pdf file.

 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);                
            Response.Flush();

The following additional info shows into my pdf file at the bottom.

//var theForm = document.forms['form1']; if (!theForm) { theForm = document.form1; } function __doPostBack(eventTarget, eventArgument) { if (!theForm.onsubmit || (theForm.onsubmit() != false)) { theForm.__EVENTTARGET.value = eventTarget; theForm.__EVENTARGUMENT.value = eventArgument; theForm.submit(); } } //

How can I get rid of above additional info during exporting page to Pdf?

Any kind of hints or sample code would be appreciated.

I had the same problem. Try to delete AllowPaging="true" and AllowSorting="true" from your asp gridview in aspx file. My problem is solved.
