public event AppointmentItemOperationEventHandler CustomAllowAppointmentDrag
Public Event CustomAllowAppointmentDrag As AppointmentItemOperationEventHandler
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. |
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.
