SchedulerDataStorage.AppointmentsChanged Event

Fires when the appointments’ properties have been changed.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v22.1.dll

NuGet Package: DevExpress.Win.Scheduler


public event PersistentObjectsEventHandler AppointmentsChanged

Event Data

The AppointmentsChanged event's data class is PersistentObjectsEventArgs. The following properties provide information specific to this event:

Property Description
Objects Gets the persistent objects for which the event occurs.


The AppointmentsChanged event is raised after appointments’ properties have been changed. The appointments whose properties have been changed are identified by the event parameter’s PersistentObjectsEventArgs.Objects property.

Note that when an appointment is resized, its start/end times are changed, so the AppointmentsChanged event fires. You can use this event to be notified of any user operations which affect appointments - resizing, moving, dragging.

If you modify multiple appointments in code, and wrap this code in BeginUpdate \ EndUpdate method calls, the event fires only once.


Do not modify the SchedulerDataStorage data (i.e., change the AppointmentCollection collection, the Appointment items, etc.) within this event handler. Otherwise, the declared changes might be lost and won’t take effect at runtime.
