The BusinessDays property is used when a CalendarView is applied to the container object's CurrentView property. BusinessDays contains a logical OR of one or more of the constants used in the RecurrencePattern object's DayOfWeekMask property.
The BusinessDays property can be set from the Session object's "WorkingDays" option. It defaults to 62 (CdoMonday | … | CdoFriday) if not set. The session's options are set by its SetOption method and retrieved with its GetOption method.
The session's "WorkingDays" option and the container renderer's BusinessDays property are not automatically kept in synchronization. Changing one does not cause the other to be changed. Your application is responsible for setting each of them as appropriate.
