Comparison of collectionviewsource observablecollection (collectionview and collectionviewsource pagedcollecti

Collectionviewsource does not seem to have been deleted.

The observablecollection class implements both the inotifypropertychanged interface and the inotifycollectionchanged interface. The observablecollection class can not only implement add, remove, clear, and insert operations, but also trigger the propertychanged event.

 

 

Although the above observablecollection is very useful and inherits the inotifypropertychanged interface, sometimes we need to sort, filter, and pagination the collection. In this case, we need to use the icollectionview interface, also inherits the inotifycollectionchanged interface. The icollectionview interface has a subclass in Silverlight: pagedcollectionview, and a subclass in WPF: listcollectionview.
