Hi,
I have one Microsoft chart. I want to export that chart into pdf on button click.
This is my code in button click.

C#

Response.Clear();
        Response.AddHeader("content-disposition", "attachment;filename=ForwardLoadHistory.pdf");        
        Response.ContentType = "application/pdf";        
        Response.Charset = "";
        StringWriter stringWriter = new StringWriter();
        HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
        chtEstHoursRemaining.RenderControl(htmlWriter);
        Response.Output.Write(stringWriter.ToString());
        Response.Flush();
        Response.End();

File is downloading .It is rendering properly. When i open file in wordpad it is properly showing rendered text but when i try to open file it is giving following error.

HTML

" Adobe reader could not open file 'ForwardLoadHistory.pdf' because it is either not a supported file type or because the  file has been damaged(for example it was sent as an email attachment and wasn't corrcetly decoded)".

I try to do it with ITextSharp but is giving me following error while parsing.

Illegal characters in path

Please give some helpful solution.

Response.ContentType = "application/pdf"; Response.AddHeader("content-disposition", "attachment;filename=Vendors List.pdf"); Response.Cache.SetCacheability(HttpCacheability.NoCache); StringWriter sw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(sw); hw.Write("<center><h3>Vendors List</h3></center><br /><br /><br /><br />"); grdVendorList.AllowPaging = false; grdVendorList.DataBind(); grdVendorList.RenderControl(hw); StringReader sr = new StringReader(sw.ToString()); Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f); HTMLWorker htmlparser = new HTMLWorker(pdfDoc); PdfWriter.GetInstance(pdfDoc, Response.OutputStream); pdfDoc.Open(); htmlparser.Parse(sr); pdfDoc.Close(); Response.Write(pdfDoc); Response.End();
