CollectionView::PassesFilter Method (Object^)
Returns a value that indicates whether the specified item in the underlying collection belongs to the view.
Assembly: PresentationFramework (in PresentationFramework.dll)
Unlike the Contains method, this method assumes that the specified item belongs to the underlying collection. This method takes filters into account. Typically, you use this method during collection-changed notifications to determine if the added or removed item requires processing.
