Printing in ASP.NET

One of the most common functionality in any ASP.NET application is to print forms and controls.

In this article, I am going to show how can we achieve this print functionality in our application. For this, I created a PrintHelper class. In this class, I made a method 'PrintWebControl'. With this method we can print any server control alike GridView, DataGrid, Panel, TextBox etc.

This is my PrintHelper.cs


using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.IO;

using System.Text;

using System.Web.SessionState;


/// <summary>

/// Summary description for PrintHelper

/// </summary>

public class PrintHelper


    public PrintHelper()



        // TODO: Add constructor logic here



    public static void PrintWebControl(Control ctrl)


        PrintWebControl(ctrl, string.Empty);



    public static void PrintWebControl(Control ctrl, string Script)


        StringWriter stringWrite = new StringWriter();

        System.Web.UI.HtmlTextWriter htmlWrite = new System.Web.UI.HtmlTextWriter(stringWrite);

        if (ctrl is WebControl)


            Unit w = new Unit(100, UnitType.Percentage); ((WebControl)ctrl).Width = w;


        Page pg = new Page();

        pg.EnableEventValidation = false;

        if (Script != string.Empty)


            pg.ClientScript.RegisterStartupScript(pg.GetType(), "PrintJavaScript", Script);


        HtmlForm frm = new HtmlForm();


        frm.Attributes.Add("runat", "server");




        string strHTML = stringWrite.ToString();








Here, in this application, I created 2 pages. First is the default page of the content that I want to print.On the same page, I set a Print button also. When it will be clicked, it will redirect the user to the second page, named as 'Print.aspx'.


@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">

<html xmlns="">

<head runat="server">

    <title>Pring in ASP.NET</title>



    <form id="form1" runat="server">


            <asp:Button ID="btnPrint" runat="server" Text="Print" OnClick="btnPrint_Click" /><br />

            <asp:Panel ID="pnl1" runat="server">

                <table cellpadding="4" cellspacing="4" width="50%" align="center">


                        <td align="center">

                            Fill all information





                            <asp:Label ID="Label1" runat="server" Text="Email" Width="130px"></asp:Label>

                            <asp:TextBox runat="server"></asp:TextBox>





                            <asp:Label ID="Label2" runat="server" Text="Name" Width="130px"></asp:Label>

                            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>





                            <asp:Label ID="Label6" runat="server" Text="Country" Width="130px"></asp:Label>

                            <asp:TextBox ID="TextBox5" runat="server"></asp:TextBox>





                            <asp:Label ID="Label3" runat="server" Text="Mobile" Width="130px"></asp:Label>

                            <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

Click event of 'print' button is:

void btnPrint_Click(object sender, EventArgs e)


        Session["ctrl"] = pnl1;

        ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>'Print.aspx','PrintMe','height=300px,width=300px,scrollbars=1');</script>");


When, the 'Print' button is clicked,screen will be looking as under in the Image 2


Image 2.

Following is the load event of this page, 'Print.aspx':

void Page_Load(object sender, EventArgs e)


        Control ctrl = (Control)Session["ctrl"];
