IsSynchronizedWithCurrentItem attribute and current item updates

Question

I have a view model to manage a dialog type of view that allows filtering of a listing (if necessary) and selection of an item. The code works fine whether I set IsSynchroni

Answer 1

IsSynchronizedWithCurrentItem syncs the CurrentItem of the default CollectionView of the bound collection with the SelectedItem of your control.

Since you never use the CurrentItem of the CollectionView and you do not appear to bind to the same collection twice setting the property in question has no visible effect at all.
