easiest way to renew Datacontext binding in WPF

What is the fastest way to update my DataContext binding to my WPF usercontrol so that it shows changes in the object it is bound to in the view?

Binding an ObservableCollection (which implements a specific interface) with objects that implement INotifyPropertyChanged will immediately show changes to their values in the front end or backend whenever you make changes, as long as the binding modes are set to two way binding.

The best option is to make your DataContext object implement INotifyPropertyChanged. Make any collections implement INotifyCollectionChanged (ie: use an ObservableCollection<T> instead of List<T>, etc).

If you do this, then the bindings will automatically stay up to date, with no effort on your part.
