public event EventHandler<DataTransferEventArgs> TargetUpdated
<object TargetUpdated="EventHandler"/>

This event surfaces the TargetUpdated event that is raised by any Binding associated with this element. This usually means that the binding in question is a two-way binding, and that the bound dependency property affirms an invalidation of the previous property value per any validation or caching scheme that the property supports.

The event arguments of this event will inform you which bound property was changed.
