InvalidOperationException

The binding has been detached from its target.

This enables you to force a data transfer from the source property to the target property. If your source object implements a proper property changed notification mechanism such as INotifyPropertyChanged target updates happen automatically. However, you have the option to use this method to update the target property explicitly in cases where your source object does not provide the proper property changed notifications. You can also use this method if your application needs to update the target properties periodically.
