Scenario:
- Windows Form
- Listbox
- SelectionMode = MultiSimple
- Items 1 and 5 are selected already
- User selects item 3 by clicking on it or by pressing the spacebar after it has focus
Q: How do I get its index or value on SelectionChanged? I.e., how do I know which item was just selected (or de-selected)? FYI, SelectedItem will return item 1 (i.e., the item at index 0 in the SelectedItems collection).
