>>I use listboxes instead of grids and what I did was add several methods that handled the loading of a specified number of items. In my case I load 30 items and when the user scrolls past them I load the next 30 etc. They never know that I have not loaded the entire table. So I can handle an unlimited number of records this way.

>About Treeview control.. We have that deal of "dummy" sub-node that we changed for sub-nodes on expand method.. This behavior works like a kind of community's standard (or Windows maybe).. My point is about to know if there is any "standard" for listview.. Following the idea of Simon we can fill it with 30 more.. But on listview (I believe) we don't have any method that works for specific behavior of scroll.. We can trap keypress (up,down) or mouse..

I trapped for upArrow, dnArrow, pgUp, pgDn and the mouse being down over the scrollUp/scrollDown buttons. I can email you the code for you to look at if it helps.
