ok, I am looking whole day and I can't find it.

I have a listview box and Scrollable is set to True
so I can use the slider on the right site,
but what is the event for the scroll slider WITHIN that listview, so I am not talking about the external scrollbar, to do some calculatings for that.

What I want is a Listview box and I want to load 145000 lines,
since that is VERY slow, I only want to do is load 10 lines, and when I use the scrolbar on the right, add 1 row and delete the 1st row within the listview box, but I can't find the property/event for that scrollbar.

Thanks so much
