The example below illustrates how to assign a specific label to appointments that intersect another appointment.

private void Scheduler_ResizeAppointmentOver(object sender, DevExpress.Xpf.Scheduling.ResizeAppointmentOverEventArgs e) {
    //if a resized appointment intersects another appointment, paint it red to indicate a conflict
    if (e.ConflictedAppointments.Count > 0)
        e.ResizeAppointment.LabelId = 1;
    //roll the label back if no conflicts are detected
    if (e.ConflictedAppointments.Count == 0)
        e.ResizeAppointment.LabelId = e.SourceAppointment.LabelId;
}
