Customize calendar border?

May 15, 2013 at 9:58 AM
Is it possible to customize color of the calendar borders (ones drawn around each day box, and ones drawn around "prev/next month" buttons) ?

I've tried to do the following, but it doesn't work:
this.Cal.BorderBrush = new SolidColorBrush(Colors.Black);

If the styling is an answer, it would help to have some sample code :-)
Thanks for the great code.
