[BUG] calendar control

[luca]

i'm using a calendar control on a web form
(C# code behind)

if i try to assign a css style to NextPrevStyle,
at runtime only font i respected, color is ignored;
if i set NextPrevStyle.ForeColor it is keep

the same for Calendar
control,SelectedDayStyle,CalendarTitleStyle; others
styles works fine with css.

i think it's a bug of the control, any idea ?!
