DispatcherTimer.Tick Event

Occurs when the timer interval has elapsed.

Namespace: System.Windows.Threading
Assembly: WindowsBase (in windowsbase.dll)

public event EventHandler Tick
/** @event */
public void add_Tick (EventHandler value)

/** @event */
public void remove_Tick (EventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
 This event is not typically used in XAML. 

The following example creates a Tick event handler. The event handler updates a Label which displays the current second and it calls InvalidateRequerySuggested on the CommandManager.

//  System.Windows.Threading.DispatcherTimer.Tick handler
//
//  Updates the current seconds display and calls
//  InvalidateRequerySuggested on the CommandManager to force 
//  the Command to raise the CanExecuteChanged event.
private void dispatcherTimer_Tick(object sender, EventArgs e)
{
    // Updating the Label which displays the current second
    lblSeconds.Content = DateTime.Now.Second;

    // Forcing the CommandManager to raise the RequerySuggested event
    CommandManager.InvalidateRequerySuggested();
}
