ensureCellIsVisible for real

I am working on text search in DataGrid. When text instances found I am
scrolling it to the first instance using ensureCellIsVisible. Works fine as
long as the whole DG is visible, But if a part of it is underneath of the
screen which has a vertical scroll bar the instances of found text are not
visible. I would need to scroll thee screen to position the DG in he
visible area. Any idea how to architect this task?

Thanks

Well, that wasn't very nice of us, was it?  I guess it is private because
we constantly muck with it during touch scrolling effects.

Try verticalScrollBar.contentMaximum.
