In order for a ListBox
to update dynamically as items are added to the list, you need to choose a collection class that raises events when items are added / removed. You should use ObservableCollection
as your ItemsSource
. This collection raises the CollectionChanged
event when it is modified. ListBox
handles this event and updates accordingly.
