CollectionView.PassesFilter Method

.NET Framework 4.5

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.

Remarks

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.
