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)
abstract PassesFilter : item:Object -> bool override PassesFilter : item:Object -> bool
The item to check.
Return ValueType: System.Boolean
true if the specified item belongs to the view or if there is not filter set on the collection view; otherwise, false.
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.
