It sounds like you want the behaviour of a virtual ListView, where the data to draw each item, is asked for as items are scrolled into view. This is no problem in Win32/MFC, but the stock .Net ListView does not do this.

Even if you could monitor the scrolling events and try anticipating when certain items need full data, the LV's item collection would need to be filled with correct number of items first, else the scroll thumb and behaviour would be somewhat strange. My own experience suggests that adding items, even if they have blank data, is somewhat expensive in itself, unlike with a straight Win32 LV. The .Net LV tracks its own cache of at least certain data for each item, in its own collection.

There might be a 3rd party solution, but unfortunately I do not know of one. Implementing it would have to be largely from scratch, except for inheriting from Control, using delegates to retrieve data to be loaded into the rows. There are some articles on this site about custom drawing LVs, which might be of interest to you. Sorry I couldn't be more helpful.

Cheers
