  public void htmlstr()
        {
            string filename = "A"; 
           sb.Append(" <html><body><table width='100%' cellspacing='0' cellpadding='2'  >");
            sb.Append("<tr><td colspan='4'></td></tr>");
            sb.Append("<tr><td></td><th><img id='alogo'  height='75' width=75' src=" + Server.MapPath("~/images/ logo.png") + "></th><td><img id='xlogo'  height='75' width=75' src=" + Server.MapPath("~/images/ logo.png") + "></td><td></td></tr>");
          
            sb.Append("<tr><td colspan='4'>Date :"  + DateTime.Now.ToString("dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture) +"</td></tr>");
            sb.Append("<tr><td colspan='4'></td></tr>");
            sb.Append("<tr><td colspan='4'>Hello</td></tr>");
            sb.Append("<tr><td colspan='4'></td></tr>");
            sb.Append("<tr><td colspan='4'></td></tr>");
            sb.Append("<tr><td></td><td colspan='2'>test matter</td><td></td></tr>");
            sb.Append("<tr><td></td><td colspan='2'>test matter</td><td></td></tr>");
            sb.Append("<tr><td></td><td colspan='2'>test matter</td><td></td></tr>");
           
            sb.Append("<tr><td colspan='4'></td></tr>");
            sb.Append("<tr><td></td><td colspan='2'> test</td><td></td></tr>");

            sb.Append("<tr><td></td><td colspan='2'>test</td><td></td></tr>");
            sb.Append("<tr><td colspan='4'></td></tr>");
            sb.Append("<tr><td colspan='4'></td></tr>");
         

            sb.Append("<tr><td></td><td colspan='2'>Test footer</td><td></td></tr>");
            sb.Append(" </table></body></html>");


            divpdf.InnerHtml = sb.ToString();
            System.IO.StreamWriter s = new System.IO.StreamWriter( filename, false);
            s.WriteLine(divpdf.InnerHtml);
            s.Close();
        
        }


              public void convert2pdf()
        {
            
            string filename =  "A";
            Response.ContentType = "application/pdf";
            Response.AddHeader("content-disposition", "attachment;filename=" + filename + ".pdf");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            StringWriter sw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            divpdf.RenderControl(hw);
            StringReader sr = new StringReader(sw.ToString());
            Document pdfDoc = new Document(PageSize.A4.Rotate(), 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();
            

        }

sb.Append("<tfoot>"); sb.Append("<tr><td></td><td colspan='3'>footer </td><td></td></tr>."); sb.Append("</tfoot>");

and since it is working. Kindly mark as Answer. and for more questions. Create a new thread.

Hi svibuk,

It seems you're not calling htmlstr() in oage load. Your pageload event should be something like this.

protected void Page_Load(object sender, EventArgs e) { htmlstr(); convert2pdf(); }

Thanks,

RajeshV.

Mistakes in your code.

HTML incorrect. TH placed below TDs.
Missing End Tags.
Image Tag Path wrong. Server.MapPath gets the File Path on Disk (eg. D:\images\logo.png) while PDF needs a URL eg. http://localhost:4503/images/logo.png

Here is the working solution

    protected void ExportToPDF(object sender, EventArgs e)
    {
        StringBuilder sb = new StringBuilder();
        sb.Append("<table width='100%' cellspacing='0' cellpadding='2'>");
        sb.Append("<tr><td colspan='4'></td></tr>");
        sb.Append("<tr><td></td><td><img alt='alogo' height = '50' width = '50' src=" + GetUrl("images/logo.png") + " /></td><td><img alt='xlogo' height = '50' width = '50' src=" + GetUrl("images/logo.png") + " /></td><td></td></tr>");
        sb.Append("<tr><td colspan='4'>Date :" + DateTime.Now.ToString("dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture) + "</td></tr>");
        sb.Append("<tr><td colspan='4'></td></tr>");
        sb.Append("<tr><td colspan='4'>Hello</td></tr>");
        sb.Append("<tr><td colspan='4'></td></tr>");
        sb.Append("<tr><td colspan='4'></td></tr>");
        sb.Append("<tr><td></td><td colspan='2'>test matter</td><td></td></tr>");
        sb.Append("<tr><td></td><td colspan='2'>test matter</td><td></td></tr>");
        sb.Append("<tr><td></td><td colspan='2'>test matter</td><td></td></tr>");

        sb.Append("<tr><td colspan='4'></td></tr>");
        sb.Append("<tr><td></td><td colspan='2'> test</td><td></td></tr>");
        sb.Append("<tr><td></td><td colspan='2'>test</td><td></td></tr>");
        sb.Append("<tr><td></td><td colspan='2'>test</td><td></td></tr>");
        sb.Append("<tr><td colspan='4'></td></tr>");
        sb.Append("<tr><td colspan='4'></td></tr>");


        sb.Append("<tr><td></td><td colspan='2'>Test footer</td><td></td></tr>");
        sb.Append(" </table>");
        StringReader sr = new StringReader(sb.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.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment;filename=HTML.pdf");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Write(pdfDoc);
        Response.End();
    }

    private string GetUrl(string imagePath)
    {
        string[] splits = Request.Url.AbsoluteUri.Split('/');
        if (splits.Length >= 2)
        {
            string url = splits[0] + "//";
            for (int i = 2; i < splits.Length - 1; i++)
            {
                url += splits[i];
                url += "/";
            }
            return url + imagePath;
        }
        return imagePath;
    }
