The All-Day area is used to display the appointments scheduled for the whole day (those with the Appointment.AllDay property set to true) and the appointments which start on one day and finish on another.
The All-Day area element is specific to the Day View and Work Week View views of the XtraScheduler control. The height of the All-Day area element depends on the number of all-day appointments, but does not exceed 50% of the current view height. When all-day area cannot be extended to fit all appointments, the scrollbar is displayed if the DayView.AllDayAreaScrollBarVisible property is set to true.
The following table lists the properties that affect the element's appearance:
The user can hide the All-Day area by setting the DayView.ShowAllDayArea property value to false.
