You can try to

- store last item index in some class field, say CachedItemNo

- when you need the actual item index, use a function like

if (CachedItemNo<0) or (CachedItemNo>=RVData.Items.Count) or

  (RVData.GetItem(CachedItemNo)<>Self) then

  CachedItemNo := RVData.GetItemNo(Self);

Result := CachedItemNo;

where RVData is an object containing this item.

RichView tables work in this way.
