As far as I understand, the class
BindingNavigator
is for Forms only:

^]; there is no analogous WPF control.
Therefore, the question does not make much sense. You would need to describe the functionality you need, from the point of view of the application, to try to get an advice on what would be the best way of implementing the features you need. Generally, the idea of "conversion" to WPF is not very fruitful: if you do it without some UI redesign leveraging WPF approaches, this is most likely the waste of time. If you do such redesign, it would be pretty much development of new UI, which hardly can be called "conversion"…
