Esempio di controllo DatePickerTemplate
Nell'esempio seguente viene illustrato come definire un ControlTemplate oggetto per il DatePicker controllo .
<!--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.-->
