Gets or sets a value that indicates whether filtering data in real time is enabled.
Assembly: WindowsBase (in WindowsBase.dll)
Your CollectionView can implement live filtering itself, or you can delegate live filtering to another object, such as the underlying collection. If you delegate live filtering, the CollectionView might not have control over whether it is enabled. Your CollectionView must accept the behavior of the object to which it delegates. If your CollectionView knows whether the delegate object supports live filtering, set the property to the known value. Otherwise, set to null.
