Hi ,

I am trying to export the contents in a asp.net panel to a pdf  file using the itextsharp.dll, it works in a asp.net web application but in a dotnetnuke module a runtime error occurs as

Control  of type 'Panel' must be placed inside a form tag with runat=server.

Can someone please help me solve this error

The code to export is like this

protected void btnExport_Click(object sender, EventArgs e)
        {
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            StringWriter sw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            pnlData.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();
        }

This is the View.ascx
