Export Div Content to PDF Using ITextSharp

This article explains how to export content in a div to a PDF using iTextSharp.

What is ITextSharp

iTextSharp is a free and open source assembly that helps to convert page output or HTML content in A PDF file.

You can download IT from here:

http://sourceforge.net/projects/itextsharp/

Now add that DLL to the application.

Getting Started

Start Visual Studio and create a new website in ASP.Net and add these 2 DLLs to the solution.

• Itextsharp.dll
• itextsharp.pdfa.dll

Now add these namespaces:

• using iTextSharp.text;
   
• using iTextSharp.text.pdf;
• using iTextSharp.text.html;
• using iTextSharp.text.html.simpleparser;
• using System.Data.SqlClient;
• using System.Configuration;

This is my div content:

<div id="employeelistDiv" runat="server">

    <table border="1">

        <tr>

            <td colspan="2">

                <b>Employee Detail</b>

            </td>

        </tr>

        <tr>

            <td><b>EmployeeID:</b></td>

            <td><asp:Label ID="lblEmployeeId" runat="server"></asp:Label></td>

        </tr>

        <tr>

            <td><b>FirstName:</b></td>

            <td><asp:Label ID="lblFirstName" runat="server"></asp:Label></td>

        </tr>

        <tr>

            <td><b>LastName:</b></td>

            <td><asp:Label ID="lblLastName" runat="server"></asp:Label></td>

        </tr>

        <tr>

            <td><b>City:</b></td>

            <td><asp:Label ID="lblCity" runat="server"></asp:Label></td>

        </tr>

           <tr>

            <td><b>Region:</b></td>

            <td><asp:Label ID="lblState" runat="server"></asp:Label></td>

        </tr>

         <tr>

            <td><b>Postal Code:</b></td>

            <td><asp:Label ID="lblPostalCode" runat="server"></asp:Label></td>

        </tr>

           <tr>

            <td><b>Country:</b></td>

            <td><asp:Label ID="lblCountry" runat="server"></asp:Label></td>

        </tr>      

    </table>

</div>

<asp:Button ID="btnExport" runat="server" Text="Export" OnClick="btnExport_Click" />

Code behind:

protected void Page_Load(object sender, EventArgs e)

{

    if (!IsPostBack)

    {

        string ConString = ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;

            SqlConnection con = new SqlConnection(ConString);

            SqlCommand cmd = new SqlCommand();

            cmd.CommandText = "SELECT TOP 1 EmployeeID, LastName, FirstName, Title, BirthDate, City, Region, PostalCode, Country FROM Employees";

            cmd.Connection = con;

            con.Open();

            DataTable dt = new DataTable();

            dt.Load(cmd.ExecuteReader());

            if (dt.Rows.Count > 0)

            {               

                //Bind Datatable to Labels

                lblEmployeeId.Text = dt.Rows[0]["EmployeeID"].ToString();

                lblFirstName.Text = dt.Rows[0]["FirstName"].ToString();

                lblLastName.Text = dt.Rows[0]["LastName"].ToString();

                lblCity.Text = dt.Rows[0]["City"].ToString();

                lblState.Text = dt.Rows[0]["Region"].ToString();

                lblPostalCode.Text = dt.Rows[0]["PostalCode"].ToString();

                lblCountry.Text = dt.Rows[0]["Country"].ToString();

            }

            con.Close();          

        }
}

protected void btnExport_Click(object sender, EventArgs e)

{

    Response.ContentType = "application/pdf";

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

    Response.Cache.SetCacheability(HttpCacheability.NoCache);

   

    StringWriter stringWriter = new StringWriter();

    HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);

    employeelistDiv.RenderControl(htmlTextWriter);

   

    StringReader stringReader = new StringReader(stringWriter.ToString());

    Document Doc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);

    HTMLWorker htmlparser = new HTMLWorker(Doc);

    PdfWriter.GetInstance(Doc, Response.OutputStream);

   

    Doc.Open();

    htmlparser.Parse(stringReader);

    Doc.Close();

    Response.Write(Doc);

    Response.End();

}

 

public override void VerifyRenderingInServerForm(Control control)

{
