Exemple ControlTemplate DatePicker

L’exemple suivant montre comment définir un ControlTemplate pour le contrôle DatePicker.

<!--In this example, an implecit style for Calendar is defined elsewhere 
  in the application.  DatePickerCalendarStyle is based on the implicit 
  style so that the DatePicker will use the application's calendar style.-->
