Question

I am trying to do a simple countdown timer from 1 minute, that is shown in the button text. When the button is pressed I just want it to count down to 0, the show “times up”. I have been reading all the posts I can find trying to figure out how to do this and cannot. Can someone tell me what I am doing wrong.

This is in in visual c# windows phone application. I hope I made the post appear correctly, this is my first time to ask a question on this site, I am new to this. Thank you in advance for any advice.

void bTime_Click(object sender, RoutedEventArgs e)
    {
        DispatcherTimer timer1 = new DispatcherTimer();
        timer1.Interval = TimeSpan.FromSeconds(60);
        timer1.Tick += new EventHandler(timer_Tick);
        timer1.Start();
    }

    int tik = 60;
    void timer_Tick(object sender, EventArgs e)
    {
        bTime.Content = timer.ToString();
        if (tik > 0)
            Countdown.Text = (timer--).ToString();
        else
            Countdown.Text = "Times Up";
        throw new NotImplementedException();
    }

First, get rid of throw new NotImplementedException. Second, you need to decrement tik. So something like this:

    DispatcherTimer timer1 = new DispatcherTimer();
    private void button1_Click(object sender, RoutedEventArgs e)
    {
        timer1.Interval = new TimeSpan(0, 0, 0, 1);
        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Start();
    }

    int tik = 60;
    void timer1_Tick(object sender, EventArgs e)
    {
        Countdown.Text = tik + " Seconds Remaining";
        if (tik > 0)
            tik--;
        else
            Countdown.Text = "Times Up";
    }

I have changed Interval and i’m decrementing tik every second. Nice and simple. Hope it helps. Let me know if you don’t understand.
