SchedulerControl.AppointmentResizing Event

Occurs when an end-user begins modifying the appointment's interval, by dragging its border with the mouse.

Namespace:DevExpress.Xpf.Scheduler
Assembly:DevExpress.Xpf.Scheduler.v19.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type AppointmentResizeEventArgs containing data related to this event.

The following AppointmentResizeEventArgs properties provide information specific to this event.
Property Description
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.

Expanded Remarks

Important

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.

Note

To cancel appointment resizing, handle the AppointmentResized event, and set the DevExpress.XtraScheduler.AppointmentResizeEventArgs.Allow to false and DevExpress.XtraScheduler.AppointmentResizeEventArgs.Handled to true, in the handler's code.

The OptionsCustomization.AllowAppointmentResize value takes priority over the AppointmentResizing event. If it is set to DevExpress.XtraScheduler.AppointmentConflictsMode.Custom, then the AllowAppointmentResize occurs before the AppointmentResizing event. Dragging the appointment border with the mouse results in a series of AppointmentResizing events, followed by a single AppointmentResized event.
