This article will show you how you can export html content to pdf in your asp.net application using iTextSharp.

So first we will create a new asp.net application an then install the nuget package for iTextSharp. Please check the below link and screen show.

https://www.nuget.org/packages/iTextSharp/

Now open package installer and install the nuget package.

After installing add a button control in your page and generate the click event.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>

<!DOCTYPE html>

</head>

<body>

<h3>Export Html to PDF</h3><br />

<div>

<asp:Button ID="Button1" runat="server" Text="Export HTML to PDF" OnClick="Button1_Click" />

</div>

</form>

</body>

</html>

Now in your code behind add the below code to export the html content from code behind to pdf.

using iTextSharp.text;

using iTextSharp.text.html.simpleparser;

using iTextSharp.text.pdf;

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Text;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace WebApplication1

{

public partial class WebForm1 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

string htmlcontent = HTMLString();

Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);

PdfWriter.GetInstance(pdfDoc, Response.OutputStream);

pdfDoc.Open();

List htmlarraylist = HTMLWorker.ParseToList(new StringReader(htmlcontent), null);

for (int k = 0; k < htmlarraylist.Count; k++)

{

pdfDoc.Add((IElement)htmlarraylist[k]);

}

pdfDoc.Close();

Response.ContentType = "application/pdf";

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

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Response.Write(pdfDoc);

}

public string HTMLString()

{

StringBuilder htmltext = new StringBuilder();

htmltext.Append("<div><h1>Welcome To aspdotnetpools</h1></div>");

htmltext.Append("<table width='100%' border='1'>");

htmltext.Append("<tr>");
