Hello, i need to build an app that use a countdown (Years, Days, Hour, Minutes, Seconds). I've tried to write a code and i succeed to calculate the time, but when i try to put this time as a string in a texblock, he is not updating. Can anyone help me to set the textblock to update himself ?
Notice: I'm a beginner in C# and Metro App's. And sorry for my bad english.

    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
        }

        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
        }

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {

            DispatcherTimer t = new DispatcherTimer();
            DateTime endtime = new DateTime(2012, 12, 25, 0, 0, 0);
            DateTime now = DateTime.Now;
            t.Interval = endtime - now;
            TimeSpan ts = t.Interval;
            t.Start();

            string countDown = string.Format("{0} Days, {1} Hours, {2} Minutes, {3} Seconds til Christmas.", t.Interval.Days, t.Interval.Hours, t.Interval.Minutes, t.Interval.Seconds);
            Day_TxtBlk.Text = countDown;
        }

        private void Day_TxtBlk_Loaded(object sender, RoutedEventArgs e)
        {
            
        }



    }
}

I found the solution to my problem.

C#

void t_Tick(object sender, object e)
        {
            TimeSpan ts = endtime.Subtract(DateTime.Now);

            string countdowndays = ts.Days.ToString();
            daytxtblk.Text = countdowndays;

            string countdownhours = ts.Hours.ToString();
            hourstxtblk.Text = countdownhours;

            string countdownminutes = ts.Minutes.ToString();
            minutetxtblk.Text = countdownminutes;

            string countdownseconds = ts.Seconds.ToString();
            sectxtblk.Text = countdownseconds;
        }


        private void christmas_2012_Click(object sender, RoutedEventArgs e)
        {
            

            if (this.IsEnabled)
            {
                txtboxchr.Visibility = Visibility.Visible;
                txtboxhours.Visibility = Visibility.Visible;
                txtboxminutes.Visibility = Visibility.Visible;
                txtboxseconds.Visibility = Visibility.Visible;

                daytxtblk.Visibility = Visibility.Visible;
                hourstxtblk.Visibility = Visibility.Visible;
                minutetxtblk.Visibility = Visibility.Visible;
                sectxtblk.Visibility = Visibility.Visible;
            }
           

            t = new DispatcherTimer();
            endtime = new DateTime(2012, 12, 25, 0, 0, 0);
            
            if (DateTime.Now.Year > endtime.Year)
            {
                t.Stop();
                txtboxchr.Visibility = Visibility.Collapsed;
                txtboxhours.Visibility = Visibility.Collapsed;
                txtboxminutes.Visibility = Visibility.Collapsed;
                txtboxseconds.Visibility = Visibility.Collapsed;

                daytxtblk.Visibility = Visibility.Collapsed;
                hourstxtblk.Visibility = Visibility.Collapsed;
                minutetxtblk.Visibility = Visibility.Collapsed;
                sectxtblk.Visibility = Visibility.Collapsed;
                pleasesetdat();
            }
            else 
            {
                t.Interval = new TimeSpan(1000);
                TimeSpan ts = endtime.Subtract(DateTime.Now);
                t.Tick += t_Tick;
                t.Start();
            }
        }
