PassesFilter Method

CollectionView::PassesFilter Method (Object^)

 

Returns a value that indicates whether the specified item in the underlying collection belongs to the view.

Namespace:   System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)

public:
virtual bool PassesFilter(
	Object^ item
)

Parameters

item
Type: System::Object^

The item to check.

Return Value

Type: 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.
