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">
