Public Event AppointmentRemoving As AppointmentRemovingEventHandler
The AppointmentRemoving event's data class is AppointmentRemovingEventArgs. The following properties provide information specific to this event:
|Appointments||Returns the collection of appointments that are to be deleted.|
|Cancel||Gets or sets whether the event should be canceled. Inherited from CancelRoutedEventArgs.|
|CanceledAppointments||Provides access to the collection of appointments that should be excluded from being deleted.|
|Handled||Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.|
|Source||Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.|
The event data class exposes the following methods:
|InvokeEventHandler(Delegate, Object)||When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.|
|OnSetSource(Object)||When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.|
To prevent specific appointments from being deleted, add them to the CanceledAppointments collection. If you want to implement a custom appointment removal functionality, set the event’s Cancel property to true to disable the default mechanism.
