If the web listbox grows to the point that scroll bars would be required, is there a way to figure out from the number of rows what the size height would be without requiring a scroll bar?
Listbox.ListCount*ListBox.RowHeight
listbox.top + listbox.listcount * listbox.rowheight ,
BUT
depending on your styles etc, and the way its rendered by the browser you will still get occasions where the scrollbar will show.
i add an amount based on the rowcount so its 120% or similar, still it doesn’t always work.
