I want to start the count down timer after I click on the submit button instead of when the page is loaded

protected void Timer1_Tick(object sender, EventArgs e)
        {
            if (TimeAllSecondes > 0)
            {
                TimeAllSecondes = TimeAllSecondes - 1;
            }

            TimeSpan time_Span = TimeSpan.FromSeconds(TimeAllSecondes);
            hh = time_Span.Hours;
            mm = time_Span.Minutes;
            ss = time_Span.Seconds;

            Label2.Text = "  " + hh + ":" + mm + ":" + ss;
        }

protected void Button1_Click(object sender, EventArgs e)
       {

      }

What I have tried:

I have tried calling the Timer1_Tick method as Timer1_Tick(sender, e) within the Button1_Click method , but it didn't work.

That code is never going to work, your browser needs to request html from the server via a request which it then shows. You can't "push" content to the browser from your server code, it has to be requested, so a timer updating "Label2" server-side is not going to have Label2 updated on the client.

You'll need to solve this using client-side scripting and maybe some ajax depending on what your aim is. If it's just to show a countdown or timer then google "javascript timer" and you'll find lots of examples.

try this

protected void Page_Load(object sender, EventArgs e)
       {
           if (!Page.IsPostBack) {
               Timer1.Enabled = false;
           }
       }

       protected void Button1_Click(object sender, EventArgs e)
       {
           Timer1.Enabled = true;
       }
