Declaration
Property Value
| Type | Description |
|---|---|
| IReadOnlyList<AppointmentItem> | A list of DevExpress.Xpf.Scheduling.AppointmentItem objects that have been modified or deleted in the scheduler. |
Remarks
When a user updates or deletes a pattern, the scheduler deletes all ChangedOccurrence and DeletedOccurrence appointments for the corresponding recurring series. The Occurrence appointments are not stored in any collection to avoid a stack overflow for infinite recurring series. These appointments are automatically generated at runtime based on the pattern’s AppointmentItem.RecurrenceInfo property.
When a user updates a pattern, the scheduler only adds the pattern appointment to the UpdateInSource and Appointments lists. The ChangedOccurrence and DeletedOccurrence appointments are added to the DeleteFromSource list.
