Question

I have multiple textboxes bound to different data, but I would like every one to launch the same command when the TextChanged event is fired. I could copy the interaction line u

If your UpdateMode is always going to be PropertyChanged then there really isn't any reason not to listen to your own PropertyChangedEvent in your ViewModel. It will definitely improve testability.

    private void OnPropertyChanged(object sender, PropertyChangedEventArgs args)
    {
        switch (args.PropertyName)
        {
            case "Prop1":
            case "Prop2":
                .
                .
                .
                DataChangedCommand.Execute(null);
                break;
        }
    }
