Public Event AppointmentResizing As AppointmentResizeEventHandler
The AppointmentResizing event's data class is AppointmentResizeEventArgs. The following properties provide information specific to this event:
|Allow||Specifies whether the appointment can be resized.|
|EditedAppointment||Gets the appointment being edited in the resize event.|
|Handled||Gets or sets whether the resize operation is handled, and therefore no default processing is required.|
|HitInterval||Gets the time interval represented by the time cell to which the appointment’s side is moved.|
|HitResource||Gets the resource assigned to cells to which an appointment’s side is moved.|
|ResizedSide||Indicates which appointment side is being moved when the appointment is resized.|
|SourceAppointment||Gets the source appointment in the resize event.|
You are viewing documentation for the legacy WPF Scheduler control. If you’re starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.
The event argument provides information on an appointment before and after resizing, the resource and time interval associated with time cells to which the appointment’s edge is moved, and also indicates which side of the appointment is moved.
To cancel appointment resizing, handle the SchedulerControl.AppointmentResized event, and set the AppointmentResizeEventArgs.Allow to false and AppointmentResizeEventArgs.Handled to true, in the handler’s code.
The OptionsCustomization.AllowAppointmentResize value takes priority over the AppointmentResizing event. If it is set to AppointmentConflictsMode.Custom, then the SchedulerControl.AllowAppointmentResize occurs before the AppointmentResizing event. Dragging the appointment border with the mouse results in a series of AppointmentResizing events, followed by a single SchedulerControl.AppointmentResized event.
