Event Data
The StartAppointmentResize event's data class is StartAppointmentResizeEventArgs. 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. |
| ResizeAppointment | Returns a temporary copy of the appointment the end-user attempts to resize. This copy is passed to the QueryContinueAppointmentResizeEventArgs.ResizeAppointment event parameter. |
| ResizeHandle | Indicates whether the user drags the start or end of the appointment. |
| 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. |
| SourceAppointment | Returns the appointment the end-user attempts to resize. |
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
The ResizeHandle event’s property indicates whether the user drags the start or end of the appointment.
Data properties of the event’s ResizeAppointment propery are copied to the event’s SourceAppointment property. Set the event’s Cancel property to true to disable this behavior and manually apply the desired changes to the SourceAppointment.
