view life cycle events
We have seen that the infrastructure has a way, by default based on behaviors, to notify a ViewModel that its own View state is changing.

The View is a Window

If the view is a window we have several state that can be handled/intercepted by the coupled ViewModel:
  • Loaded;
  • Activated;
  • Shown;
  • Closing;
  • Closed;

The View is a FrameworkElement (e.g. a UserControl)

If the view is a user control the only state we can intercept is the Loaded event.
