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 asp.net 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;
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();
pg.Controls.Add(frm);
frm.Attributes.Add("runat", "server");
frm.Controls.Add(ctrl);
pg.DesignerInitialize();
pg.RenderControl(htmlWrite);
string strHTML = stringWrite.ToString();
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Write(strHTML);
HttpContext.Current.Response.Write("<script>window.print();</script>");
HttpContext.Current.Response.End();
}
}
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'.

Hai Rahul, HOw are you? and nice to see you in here. I am beginner in asp.net with c#. I am happy to copy your code, but this is not working..............
Anele NgqanduPosted Sep 7, 2011, 7:45 AM
So can this also work for printing using the gridview control?
John SmithPosted Jun 9, 2011, 3:57 AM
Hey Moron, Stop claiming things as your own. Once an idiot always an idiot. Expertise in copying is more correct.
John SmithPosted Jun 9, 2011, 3:32 AM
Hi Rahul, That's a really great article that you took credit for; you stupid Indian. Aren't you breaking the rule of copied contents? Here is the original content written over a year back before you post it as your own. http://www.dotnetcurry.com/ShowArticle.aspx?ID=92 What a retard..

Thank you for your extremelly valuabe article. It works great! I had been reading books and searching the web and nothing that I found worked as easy and straight as your code. Now, I need to add to the printing the ability to print the contents from a formview or gridview in a free format report. I am not interested in the grid but need to be able to print the records I get and print them in a loop till all of the records associated with a student are printed. Hope someone can help.. thanks!
