Export HTML To PDF

There would be some task where we need to Get PDF Format Document from html.

Following code is written under the button_click Event. 

protected void btnExportPDF_Click(object sender, EventArgs e)

{

    Response.ContentType = "application/pdf";

    Response.AddHeader("content-disposition", "attachment;filename=Investment_Declaration_Form.pdf");

    Response.Cache.SetCacheability(HttpCacheability.NoCache);

    StringWriter sw = new StringWriter();

    HtmlTextWriter hw = new HtmlTextWriter(sw);

    this.divToPdf.RenderControl(hw);

    //where divToPdf is the ContentPlaceHolder Id in which whole html contains.

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

    Document pdfDoc = new Document(PageSize.A4, 10, 10, 2, 10);

    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);

    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

    pdfDoc.Open();

    htmlparser.Parse(sr);

    pdfDoc.Close();

    Response.Write(pdfDoc);

    Response.End();

}
