SchedulerControl.CustomAllowAppointmentDrag Event

Occurs when attempting to drag an appointment to another time interval.

Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v24.2.dll

NuGet Package: DevExpress.Wpf.Scheduling

#Declaration

public event AppointmentItemOperationEventHandler CustomAllowAppointmentDrag

#Event Data

The CustomAllowAppointmentDrag event's data class is AppointmentItemOperationEventArgs. The following properties provide information specific to this event:

Property Description
Allow Gets or sets whether performing a particular action is allowed.
Appointment Gets the appointment for which the element is raised. Inherited from AppointmentItemEventArgs.
Recurring Gets whether the target appointment is recurring.

#Remarks

Handle the CustomAllowAppointmentDrag event and sets its AppointmentItemOperationEventArgs.Allow property to manage a particular case and specify whether to allow an end-user to drag an appointment. If you do not specify the required behavior manually, the SchedulerControl.AllowAppointmentDrag manages whether creating new appointments is allowed.

The appointment to be dragged uses the AppointmentItemEventArgs.Appointment property.

Set the AppointmentItemOperationEventArgs.Allow property to false to prevent an appointment from being dragged.
