Listbox scroll

Hi all.

I have a live data listbox (no paging, no rows set).
Suppose I have 300 rows in my model.
Suppose you can see about 15 rows in listbox visible area.
Programmatically (not user interactive scroll)) I need to select a row and to
show that row in the visible area.
I tryed using smartUpdate("scrollTop",value), but "value" is a pixel expression, so
it's very difficult to manage and to warrant that a selected row will be into
the visible area. Sometimes rows are a bit too top, sometimes too bottom...
Can anyone suggest me a way so that this can work in a deterministic way?

Any hints will be appreciate.

Thanks
