Occurs when the target value changes for any property binding on this element.
Assembly: PresentationFramework (in PresentationFramework.dll)
This event creates an alias for 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 that the previous property value is now invalid according to any validation or caching scheme that the property or the data source support.
Use the event data of theevent to determine the specific property that is reporting the target value update.
