Conversion from a Grid View to PDF file
<p>I am trying to convert a Grid View to a PDF file. I tried to implement this using the code below, but it results in an error saying that</p>

<blockquote>
  <p>no pdf exists</p>
</blockquote>

<p>Does anyone know what might be going wrong, or how I could approach this?</p>

<pre><code>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 = new Document(PageSize.A2, 7f, 7f, 7f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();

pdfDoc.Close(); 
</code></pre>
