Remarks
The OriginalOccurrenceEnd property stores the original Appointment.End value of an appointment occurrence before it was changed or deleted.
- For normal appointments, the OriginalOccurrenceEnd property value equals the End value.
- For patterns, the OriginalOccurrenceEnd value equals End value for patterns with an end clause, and DateTime.MaxValue for endless patterns.
- For recurring series exceptions, the OriginalOccurrenceEnd property stores the End value of a regular occurrence in the series.
Tip
Use the OriginalOccurrenceEnd property in a query when handling the SchedulerStorageBase.FetchAppointments event to retrieve exceptions for a certain interval.
The Appointment.OriginalOccurrenceStart and Appointment.OriginalOccurrenceEnd values are stored in the data source fields specified with the AppointmentMappingInfo.OriginalOccurrenceStart and AppointmentMappingInfo.OriginalOccurrenceEnd mappings. After the existing database is upgraded to add the fields, call the static helper’s OriginalOccurrenceDateHelper.Update method only once to populate the added fields.
