Re: ListBox item recycling for large lists

In MVVM you will expose an ObservableCollection for the items, and changes done to that collection will reflect in the UI.
In order to notify of changes in the data items so UI can be automatically updated, your data must implement the INotifyPropertyChanged interface.
You can read more about this in our Data Binding tutorial.
