How to auto scroll while dragging an item within ListView

I have a ListView control populated with 30 items.
ListView height only allows you to see 20 rows at a time.
I want to drag an item to the bottom of the list (to the last row), but
ListView control doesn't automatically scroll as my mouse leaves the
bottom edge of the control. Also if I'm dragging an item from the last
row to the top row, ListView doesn't scroll.
Please, please, please tell me how to make it scroll while dragging an
item. I have searched high and low for that information in "the
internets" to no avail.
