Event Data
The QueryContinueAppointmentResize event's data class is QueryContinueAppointmentResizeEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Action | Specifies whether the resize operation should continue, stop or be canceled. |
| EscapePressed | Indicates whether the user has pressed the ESC button. |
| 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 the current state of the appointment the user is resizing. |
| 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 initial state of the appointment the user is resizing. |
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
Use the Action event’s property to specify if and how the resize operation should continue. 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.
