CustomDataLockingViewController.cs

public class CustomDataLockingViewController : ObjectViewController<DetailView, Product> {
 private ProcessDataLockingInfoController lockController;

 protected override void OnActivated() {
   base.OnActivated();
   lockController = Frame.GetController<ProcessDataLockingInfoController>();
   lockController.DataLockingProcessed += OnDataLockingProcessed;
 }

 private void OnDataLockingProcessed(object sender, DataLockingProcessedEventArgs e) {
   if (e.Result == ProcessDataLockingInfoDialogResult.Refresh) {
     ObjectSpace.Refresh();
   }
 }

 protected override void OnDeactivated() {
   base.OnDeactivated();
   if (lockController != null) {
     lockController.DataLockingProcessed -= OnDataLockingProcessed;
     lockController = null;
   }
 }
}
