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 ov

As Ben Pearce answered we can use the CultureInfo Class to take care of the Custom Format, I really think is the only logical way. And if you have different dateTimePickers which have different Format, you can use:

CultureInfo ci = CultureInfo.CreateSpecificCulture(CultureInfo.CurrentCulture.Name);
ci.DateTimeFormat.LongDatePattern = "MMM.yyyy"; //This can be used for one type of DatePicker
ci.DateTimeFormat.ShortDatePattern = "dd.MMM.yyyy"; //for the second type
Thread.CurrentThread.CurrentCulture = ci;

And then you can just change the DateFormat in the .xaml document.
