How do I get the start index and number of visible items in a ListView?

Question

I have a listview working in virtual mode, in the LargeIcons view. Retrieves are expensive, so I want to ask for the data for all the visible items. How do I get the start

Answer 1

Have you seen the CacheVirtualItems event? The control will ask for a range of items instead of one-by-one. Tho, if scrolling, it still may ask for only one at a time. But pagedown/up will trigger the cache mechanism.
