How do I know when items are done loading into the tree?
TreeListView.ItemsSource = treeViewModel.Items;
How do I know when
TreeListView.HasItems == true?
Even when there are items in treeViewModel, it does not mean that there are items in TreeListView. It seems to take awhile for TreeListView.HasItems to become true. How do I know when it's done so that I could to fire an event?
