Hello
To get automatic updates from properties in the model (code) to the view (gui), there are some things you should ensure.

1) You should use Bindings from the view to the model
2) The properties in the model that are used in Bindings should also have a DependencyProperty in the class
3) The model class itself should implement the INotifyPropertyChanged interface so the properties can notify changes.
4) Lists should be ObservableCollection<> instead of List<> because it inherits the ICollectionChanged interface.

This way, you will never again worry about UpdateLayout() or DoEvents() or anything like that.

If you like to update the values "live" while running a long-running method in the model, you should run that method in a Thread, like i.e. a BackgroundWorker.

Hope it helps!
