I have a WPF TreeView which triggers a SelectedItemChanged event. Whenever I select an item in the TreeView, the SelectedItemChanged event is triggered for the selected item and all of the selected node’s ancestors in the tree.
How do I prevent the SelectedItemChanged event from firing more than once?
