I want to export asp.net page to pdf.My web page is a form where user enters some data in text boxes and radio buttons.I tried to export to PDF using Itextsharp dll but alignment is not at all perfect.And am not getting radio buttons in PDF.If I take only selected item from radio buttons list and displayed in a label then huge alignment problem.I have used below code,plz check and suggest me.

DataTable dt = new DataTable();
        protected void Page_Load(object sender, EventArgs e)
        {
           
            
            dt.Columns.Add("REquestType");
            dt.Columns.Add("Name");
            dt.Rows.Add();
            if (rbtlstRqstType.SelectedItem != null)
            {
                dt.Rows[0]["REquestType"] = rbtlstRqstType.SelectedItem.Text;
            }
            dt.Rows[0]["Name"] = txtFname.Text;

            lbllstRqstType.Text = dt.Rows[0]["REquestType"].ToString();
            lblName.Text = dt.Rows[0]["Name"].ToString();
            

        }

	try
	{


                Response.ContentType = "application/pdf";
                Response.AddHeader("content-disposition", "attachment;filename=IDform.pdf");
                Response.Cache.SetCacheability(HttpCacheability.NoCache);

                rbtlstRqstType.Visible = false;
                StringWriter sw = new StringWriter();
                HtmlTextWriter hw = new HtmlTextWriter(sw);
                //this.Page.RenderControl(hw);
                pnlIDForm.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.End();
