Gets or sets whether the current appointment lasts the entire day (or several days).
True, if this is an all-day appointment; otherwise, false.
Use the AllDay property to specify if the appointment lasts the entire day (or several days). Note that if the property is set to true, the values of the SchedulerItemBase.Start and SchedulerItemBase.End properties are ignored and instead, the Start of the appointment is considered to be 00:00 of the SchedulerItemBase.Start day, and the End of the appointment is considered to be 00:00 of the SchedulerItemBase.End day.
Regarding the time zone, all-day appointments are treated as "floating", so that they do not belong to a particular time zone. When the current time zone of the scheduler (obtained from the host settings or specified by the SchedulerControl.TimeZone property) changes, the Start and End properties of the all-day appointment remain the same.
