use the below code to convert to pdf

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition",   "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
gvdetails.AllowPaging = false;
gvdetails.DataBind();
gvdetails.RenderControl(hw);
gvdetails.HeaderRow.Style.Add("width", "15%");
gvdetails.HeaderRow.Style.Add("font-size", "10px");
gvdetails.Style.Add("text-decoration",   "none");
gvdetails.Style.Add("font-family",   "Arial, Helvetica, sans-serif;");
gvdetails.Style.Add("font-size",   "8px");
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = newDocument(PageSize.A2,   7f, 7f, 7f, 0f);
HTMLWorker htmlparser = newHTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End
