Assigning a value to this property causes the activity to assume the role of a template, i.e., it is used to define the properties of individual occurrences. This activity instance no longer appears in activity queries such as Infragistics.Scheduler.DataSource.ScheduleDataSource.GetAppointmentsInRange, but rather the occurrences it generates are displayed instead.
To make an activity a recurrence root, create an instance of the DateRecurrence class, set property values to customize the recurrence pattern, and call the DateRecurrence.ToICalendarString method to serialize the recurrence information to a string. The resulting string can then be directly assigned to this property.
