Event Data

The DropAppointment event's data class is DevExpress.Xpf.Scheduling.DropAppointmentEventArgs.


Set the event's Cancel property to true to disable the default Scheduler's drop behavior.

The example below illustrates how to override the AllowAppointmentConflicts property that is set to false.

private void Scheduler_DropAppointment(object sender, DropAppointmentEventArgs e) {
    for (int i = 0; i < e.DragAppointments.Count; i++) {
        //if a dragged appointment does not intersect another appointment
        if (e.ConflictedAppointments[i].Count == 0) {
            //it can be moved to the desired position
            e.SourceAppointments[i].Start = e.DragAppointments[i].Start;
            e.SourceAppointments[i].End = e.DragAppointments[i].End;
