Commented Unassigned: Up/Down on Keyboard not working for DataTimePicker [20963]

I've seen [this resolved bug](http://wpftoolkit.codeplex.com/workitem/20269), but I have the exact issue in my computer.

Mouse wheel (when mouse is over the DataTimePicker control) does work.
but keyboard Up/Down buttons do nothing.

I've tried to specify _CultureInfo="en-GB"_ but it changed nothing.

VS2012, Win8, Version 2.1.0.0

Hi itsho,

Yes, a movie clip could help.
Since I cannot reproduce, I'm looking for anything special that could modify the behavior of the DateTimePicker.
-Is the XAML the same as mine :
```
<xctk:DateTimePicker CultureInfo="en-GB" />
```
-Does the date part is selected when Keyboard Up/Down is pressed,
-The bug is happening with CultureInfo="en-GB", is there other cultures that work, or doesn't work.
-Could the Key event be eat by another control

Thanks a lot.
