                        Response.AddHeader("content-disposition", "attachment;filename=Commision_" + name + "_" + DateTime.Now.ToString("yyyyMM") + ".pdf");

                        Response.Cache.SetCacheability(HttpCacheability.NoCache);

                        //Render PlaceHolder to temporary stream

                        StringReader reader = new StringReader(html);

                        //Create PDF document

                        Document doc = new Document(PageSize.A4);

                        HTMLWorker parser = new HTMLWorker(doc);

                        PdfWriter.GetInstance(doc, Response.OutputStream);

                        doc.Open();
                        try
                        {
                            doc.NewPage();
                            parser.Parse(reader);
                        }
                        catch (Exception )
                        {
                        }
                        finally
                        {
                            doc.Close();
                        }

Answer 1

I guess you missed the following 2 lines after doc.close

Response.Write(doc);
Response.End();
