Event Data

The AppointmentWindowShowing event's data class is AppointmentWindowShowingEventArgs. 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.

Remarks

Handle the AppointmentWindowShowing event to specify the window displayed when editing the appointment, 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.

Tip

You can also set the OptionsWindows.AppointmentWindowType property in XAML to replace the built-in editor with a custom appointment editing window. Learn more at the How to: Customize Editing and Recurrence Dialogs topic.
