If you're doing MVVM, you could have your VM create a collection view rather than one being created on your behalf by the CollectionViewSource. Then, you have control over what type of CVS is created, so you can create a ListCollectionViewSource, which has a Count property. It really depends on the properties of the data you're filtering.
