I need to change the string format of the DatePickerTextBox in the WPF Toolkit DatePicker, to use hyphens instead of slashes for the seperators.

Is there a way to override this default culture or the display string format?

   <ControlTemplate>
    <TextBox x:Name="PART_TextBox"
     Text="{Binding Path=SelectedDate, StringFormat='dd MMM yyyy', 
     RelativeSource={RelativeSource AncestorType={x:Type DatePicker}}}" />
   </ControlTemplate>
  </Setter.Value>
 </Setter>
</Style>
