You might be able to get away with what you are trying to do, I'm not sure what the bug you are having is but it's solvable.
After you get your solution working, and if your grid is editable, you will run into a focus bug. For some reason when you prepend a control before the super.createChildren the blue editable focus window will be off by a row. It's not trivial to fix that and in my opinion best to just display your row count in separate box before your grid. You can always encapsulate the ADG as a child to your custom control instead of extending it, I know that's less ideas but keeps things in 1 place. -Tom Gruszowski, Sharply Flexing @ (http://tomek.me) --- In flexcoders@yahoogroups.com, Giuseppe Guarnieri <bepp...@...> wrote: > > Hi all!! > > I've designed an extension of AdvancedDataGrid for incorporating a set > of customer's commitments about tabular data.
