The use of state implementation is that a numeric values will show you that how many times your web page has been opened or refreshed or loaded.

So follow these steps to create State Implementation

The steps are:

1- Start -> All Programs -> Visual Studio 2005 or Visual Studio 2008

I have used to make the text as comment this is the way to make comment in this code ...
Inside the tags just u type line by line.....
Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default"
!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
html xmlns="http://www.w3.org/1999/xhtml"
head id="Head1" runat="server"
title:
form id="form1″ runat="server"
div
In between div tags you can manage your web controls like buttons, labels, picture
Box, ImageMap etc
See here is a tab named Design in the bottom of this page

5- Click on this tab and you will see a blank web page where you can drag any control from the toolbox (which is in the left side of this window)

6- Drag a Label Control in the design window or in the source window...

7-Now write this code on the top of the source window
Inside the tags place it...
%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %
script runat="server"

protected void Page_Load(object sender, EventArgs e)

{

Application["visits"] = (int)Application["visits"] + 1;

Label1.Text = Application["visits"].ToString();

}

/script
8- Now go to solution explorer and right click on the web site and choose Add New Item and add a .asax extension file.

9- Now type this code in the .asax extension file
<%@ Application Language="C#" %>

script runat="server"

void Application_Start(object sender, EventArgs e)

{

// Code that runs on application startup

Application["visits"] = 0;

}

/script


10 - Now run your web site by Ctrl + F5

11- Refresh your web page...
