How do I add/remove items to a ListView in virtual mode?

Question

If I\'m using a ListView in virtual mode then, as I understand it, the list view only keeps track of a small number of items in the list. As the user scrolls it dynamically

Answer 1

A virtual list knows nothing about your list of items. It doesn't keep track of them, not even a small set. It only ever asks "what do you want to show at the n'th row?"

If your master list changes, all you need to do is redraw the list. Invalidate() will do that for you. The listview will then ask you again what it should show at every row visible in the control.

If you are using ObjectListView, have you considered using the FastObjectListView which gives you the speed benefits of a virtual list and the ease of use of a normal ObjectListView?
