Check if button is already clicked C#

Charlotte Wahlstedt

I'm building a web application i Visual Studio using C#.

I need to check if it is the first time a button is clicked. If it is the first time I want to pick variables from one place. If it is not the first time I want to pick variable from another place.

I tried using a class Click

namespace myProject
{
public class Click
{
public int buttonclick = 0;
}
}

In button click:

Click.buttonclick++;
if (Click.buttonclick == 1)
{
MessageBox.Show("First click");
}
else
MessageBox.Show("Other clicks");

This code works the first time the web form is visited. If I go to another page and then return to this page the variable does not resets to zero. I need the variable to reset to zero every time page is visited. Is there another solution for this?

hi,
you are developing web application so you can also use javascript instead of server side code.
var p= 0;
if ("#button").click(function() {
    if(p>0)
    {
alert('other click');
    }
    else
    {
alert('first click');
    }
    p=p+1;
});
hope this will help you.

Try this instead:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Session["AlreadyClicked"] = false;
}
}

protected void Button1_Click(object sender, EventArgs e)
{
bool alreadyClicked = (bool)Session["AlreadyClicked"];
if (!alreadyClicked)
{
Label1.Text = "First click";
Session["AlreadyClicked"] = true;
}
else
{
Label1.Text = "Other clicks";
}
}
