How does the third one give me the *row numbers* of the highlighted rows other than sequentially searching for each item? That was my original question.
I want to use a collection based list box to represent data from a remote source. I only need to load enough data to display the visible rows. But the selection model that returns a collection of objects rather than the row numbers makes this impractical. I'll make a feature request.
