Changing the string format of the WPF DatePicker

Question

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?

I have solved this problem with a help of this code. Hope it will help you all as well.

<Style TargetType="{x:Type DatePickerTextBox}">  <Setter Property="Control.Template">   <Setter.Value>    <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>

It appears, as per Wonko's answer, that you cannot specify the Date format in Xaml format or by inheriting from the DatePicker.

I have put the following code into my View's constructor which overrides the ShortDateFormat for the current thread:

CultureInfo ci = CultureInfo.CreateSpecificCulture(CultureInfo.CurrentCulture.Name); ci.DateTimeFormat.ShortDatePattern = "dd-MM-yyyy"; Thread.CurrentThread.CurrentCulture = ci;
