Hi, I am having some issues creating an asp.net page using C# When you first click a button it starts the display of seconds via a label control. When you click the button again the seconds stop.

Currently my code behind looks like this:

System.Threading.Timer Timer;
bool endProcess = false;
int i = 0;

protected void Page_Load(object sender, EventArgs e)
{

  Timer = new System.Threading.Timer(TimerCallback, null, 10, 10);
}

private void TimerCallback(object state)
{
  Label1.Text = i.ToString();
  i++;
  if (endProcess == true)
  {
    Timer.Dispose();
    return;
  }
}

public void Button1_Click(object sender, System.EventArgs e)
{
  endProcess = true;
}
