DatePicker ControlTemplate Example

The following example shows how to define a ControlTemplate for the DatePicker control.

<!--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"
       TargetType="{x:Type Calendar}"
       BasedOn="{StaticResource {x:Type Calendar}}" />

<!--The template for the button that displays the calendar.-->
<Style x:Key="DropDownButtonStyle"
       TargetType="Button">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type Button}">
