Fires when the appointments’ properties have been changed.
Namespace : DevExpress.XtraScheduler
Assembly : DevExpress.XtraScheduler.v25.2.dll
NuGet Package : DevExpress.Win.Scheduler
public event PersistentObjectsEventHandler AppointmentsChanged
Public Event AppointmentsChanged As PersistentObjectsEventHandler
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.
Important
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.
The following code snippets (auto-collected from DevExpress Examples) contain references to the AppointmentsChanged event.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
