CollectionView.Refresh Method ()
Re-creates the view.
Assembly: PresentationFramework (in PresentationFramework.dll)
When you set the Filter, SortDescriptions, or GroupDescriptions property; a refresh occurs. You do not have to call the method immediately after you set one of those properties. For information about how to delay automatic refresh, see DeferRefresh.
Derived classes use the protected RefreshOverride method to override the behavior of this method.
