Solution 1

1.You should have different counters for each page, and store these counters in Application cache to be at the web application level;

2.In the Global.asax.cs init your used counter for each page like in the next example:

C#

void Application_Start(object sender, EventArgs e)
{
   Application["Page1Counter"] = 0;
   Application["Page2Counter"] = 0;
   //...
}

2.The logic for incrementing the counters for each page should be in the Page_Load event handler like in the next example:

C#

protected void Page1_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)   
    {
       int counter = (int)Application["Page1Counter"];//Get from the cache!
       counter++;
       Application["Page1Counter"] = counter; //Cache the result back!
    }
    //....
}

3.Example for your new question regarding only one page and multiple users:

C#

protected void Page1_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)   
    {
       string userID = User.Identity.Name; //Get the user ID!
       string key = string.Format("Page1CounterForUser{0}", userID);//Create the key for current user!
       int counter = (int)Application[key];//Get from the cache!
       counter++;
       Application[key] = counter; //Cache the result back!
    }
    //....
}

I have one question that this for two pages what happened i have one page only. and the data shown on that page sgould b different as per user id. then how would i count. because this time page is same and data is different as per user requirement.

Raul Iloc 23-Sep-14 7:26am

You should cache in your Application cache a key create based on the userID as key for the counter, like "string.Format("Page1CounterForUser{0}", userID);" and use these type of keys similar with "Page1Counter" in my solution above.

MAK09 23-Sep-14 7:29am

Please can u give me demo because i am not getting how to use cache

Raul Iloc 23-Sep-14 7:46am

See my update (3rd point) in my solution above.

MAK09 11-Oct-14 6:48am

what should i use in Global.asax.cs. for 3rd solution. Is like Application[key] = 0; ???

MAK09 11-Oct-14 7:00am

I tried Application["Page1CounterForUser{0}"] = 0; but getting exception.
I don't know how to use Global.asax

i used Session["ID"] to get user id.

string userID = Session["Id"].ToString();
string key = string.Format("Page1CounterForUser{0}", userID); int counter = (int)Application[key];
counter++;
Application[key] = counter;
lblCounter.Text = Application[key].ToString();

But in Global.asax. what should i write in Applicatin["?"]=0;

Raul Iloc 13-Oct-14 0:59am

In Global.asx.cs, in "Application_Start" you have to init all the used counters with value 0, like I explained in my solution above.

MAK09 13-Oct-14 4:17am

In Global.asax.cs in "Application_Start" Applicatin["Page1CounterForUser{0}"]=0; It giving me an error

Raul Iloc 13-Oct-14 4:27am

You should use Application["Page1CounterForUser1"] = 0;Application["Page1CounterForUser2"] = 0;... etc

MAK09 13-Oct-14 6:10am

O My God. if i have 100 users i have to write like this. But main problem is that i don't know how many users will register. So any dynamic method.

Raul Iloc 13-Oct-14 6:23am

You said that you want to keep the counters per each user, so you should use a for/foreach and inside of it to init each counter to 0 like in the next example:
foreach(User user in userList)
{
string key = string.Format("Page1CounterForUser{0}",user.ID);
Application[key] = 0;
}
