Question

Hi,
          I need to add header and footer in dynamic pdf

My code is ...

BaseFont bf = BaseFont.CreateFont(Environment.GetEnvironmentVariable("windir") + @"\fonts\Arial.ttf", BaseFont.IDENTITY_H, true);

      

        divexcel.Visible = true;

        Response.ContentType = "application/pdf";

        Response.ContentEncoding = System.Text.Encoding.UTF8;

        Response.AddHeader("content-disposition", "attachment;filename={0}_Final_Entry.pdf");

        Response.Cache.SetCacheability(HttpCacheability.NoCache);         

        StringWriter sw = new StringWriter();

        HtmlTextWriter hw = new HtmlTextWriter(sw);

        divexcel.RenderControl(hw);       

        StringReader sr = new StringReader(sw.ToString());

        Document pdfDoc = new Document(PageSize.A4, 80f, 80f, -2f, 35f);

        

        HTMLWorker htmlparser = new HTMLWorker(pdfDoc);

        PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

        pdfDoc.Open();

        htmlparser.Parse(sr);

        pdfDoc.Close();

        Response.Write(pdfDoc);

        Response.End();
