The event handler receives an argument of type DevExpress.XtraEditors.Calendar.SpecialCalendarDateEventArgs containing data related to this event.
Use the event's IsSpecial parameter to mark certain dates as "special"
These dates will be painted using the following appearance properties provided by the AppearanceCalendar object.
- DayCellSpecial
- DayCellSpecialDisabled
- DayCellSpecialHighlighted
- DayCellSpecialInactive
- DayCellSpecialPressed
- DayCellSpecialSelected
Another way to mark specific dates as "special" is to use the SpecialDateProvider property.
