Nevermind, I was clicking on "No Brush" and expecting it to clear the brush, but it puts it back to the default.

Is there a simple way to have the brush color not change when an item is selected?  I only want the border to change, and the interior brush to stay as it is already drawn before being selected.

I ended up writing a class to hold on to my different styles and then I assigned them to the Style and SelectedStyle.  There was lots of trial and error to get the colors just right and such. 

I noticed that there is a few collections for DayOfWeekStyles, DayStyles, and MonthStyles in the calendar control.  These are nice because they have the color picker/brush picker built in.

Would it be possible to have a collection to store styles in that can then be assigned to appointments in code?  This would make setting up the styles a lot easier than having to assign the brushes and colors manually in code.
