The best way I know this is to create a Visiblity property for your ViewModel (the one that is attached to each row in the ItemsControl) and toggle this value based on the changes of each element, presumably through a switch in each row. I don’t know about a good way to "loop and look" at these internal controls. You are much better off using your existing data binding infrastructure to manage this for you.
