Exemplo de ControlTemplate de DatePicker

O exemplo a seguir mostra como definir um ControlTemplate para o DatePicker controle.

<!--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.-->
<Style x:Key="DatePickerCalendarStyle"

       BasedOn="{StaticResource {x:Type Calendar}}" />

<!--The template for the button that displays the calendar.-->
