WPF 4.5 : Live shaping(filtering, grouping and sorting of collections)

For each item list used in a WPF application, a collection view is in fact created and used by the controls. This view enables navigation, filtering, grouping and sorting from the XAML or the code. It is a very powerful feature that is offered to the developers since a long time in WPF. In WPF 4.5 as in WPF 4.0 the grouping, sorting and filtering operations are done when the item is added to the collection or when the Refresh method is called. The drawback is that if an item property value involved in one of these operations is updated, then the sorting/grouping/filtering will not be done again. WPF 4.5 introduce a feature called live shaping which shapes the collection view in live. Let’s dig a little more this feature. This post is the tenth part of a serie on the WPF 4.5 new features.
