    Add TListItemObject(override its paint method) to the last item of the listview. When the last item is visible, voila, the paint method is triggered and you know another items are required...

    Found a way:
    After open the data set and filled the listview, set scrollPos to last item, get the scrollviewpos and so get the scrollPos to where it was, and now I got the maxscrollpos to compare with scrollviewpos. In OnScrollViewChange, compare if the current scrollviewpos is equals to maxscrollpos, get next records and recalculate maxscrollpos. Did works fine to me.
