All collections have a default CollectionView. For collections that implement IBindingListView or IBindingList, the default collection view is BindingListCollectionView. Specifically, IBindingList is required for BindingListCollectionView, and IBindingListView is an optional interface that gives additional sorting and filtering support.
If you have multiple BindingListCollectionView objects and the underlying source is a DataTable or a DataView, the view objects do not sort or filter independently. For example, if you have two BindingListCollectionView objects associated with the same DataTable and you perform sorting on one of the views, the order of items in the other view can be affected. This is because BindingListCollectionView objects use the underlying IBindingList for sorting and filtering functionalities.
