I can not think of a way to do this directly through databinding.

Personally I would have a view model behind the view, and set the views DataContext to the view model.

In the view model I would then have a property telling the view if all the textboxes are collapsed. That property would be set by code. Then bind the stackpanel visibility to that property.

(The property must either be a dependancy property, or the view model must implement INotifyPropertyChanged for the view to automatically update)
