The DeleteOccurrenceWindowShowing event's data class is DeleteOccurrenceWindowShowingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets whether the event should be canceled. Inherited from CancelRoutedEventArgs. |
| 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. |
| ViewModel | Provides access to the View Model for the invoked window. Inherited from WindowShowingEventArgs<T>. |
| Window | Gets or sets the window to which the event is raised. Inherited from WindowShowingEventArgs<T>. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| 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. |
Handle the DeleteOccurrenceWindowShowing event to specify the window displayed when deleting an occurrence, or hide it. You can specify a window for display using the WindowShowingEventArgs<T>.Window property, or not display any window at all by setting the CancelRoutedEventArgs.Cancel property to true.
