[WPF] DispatcherTimer and upgrade label

Question

Hi,

I'm using a DispatcherTimer in my UserControl:

DispatcherTimer dispatcherTimer = new DispatcherTimer();

dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);

dispatcherTimer.Interval = new TimeSpan(0, 0, 60);

dispatcherTimer.Tick += timer_Tick;

dispatcherTimer.Start();

private void dispatcherTimer_Tick(object sender, EventArgs e)

{

CommandManager.InvalidateRequerySuggested();

myOtherUserControl uc = VisualTreeHelpers.FindChild<myOtherUserControl>(this);

uc.SearchByTimer();

//uc.timerLabel.Text = label_to_do_refresh!

}

The timer works, but I would show the countdown in timerLabel.

How can I procede?

Thanks.
