Is there a straighforward way to set additional text to appear in a tooltip when a user\'s mouse is held over an item in a CheckedListBox?
What I would expect
Contrived or not; that's what there is...
I'm not aware of an easier way than you have already described (although I'd probably re-use a tooltip instance, rather than creating new all the time). If you have articles that show this, then use them - or use a 3rd party control that supports this natively (none leap to mind).
