Same ItemsSource in multiple ComboBox elements, SelectedIndex synced for all ComboBox elements, want separate

Question

I have multiple ComboBox elements. Each ComboBox's ItemsSource is bound to the same property. That property is a ListCollectionView whose underlying list is an ObservableCollection. Each ComboBox's SelectedIndex is bound to a different property. My problem is that when the user changes one ComboBox all the others are changed to the same item.

How can I make the SelectedIndex properties independent? Do I need to use something other than ListCollectionView or ObservableCollection? Would binding to something other than SelectedIndex help?

Answer 1

After some poking around I found that the ComboBox property IsSynchronizedWithCurrentItem fixed my problem. When set to false my ComboBoxes became independent.
