How about if we start a new project on Novell Forge and place that
control under SVN?
That way anybody could help you get a nice control quicker.
I am myself interested in the existence of such a control, with some
posible additions to what you have already talked about:
1. Booleans (check boxes)
2. Foreign keys (drop-down menus without the option for new strings)
3. Different number formats (#.###,## , #,###,###.## , # , ##% , etc)
I am only interested in a Gtk# fat client control, not in a ASP.NET
one, but that is a personal choice.
God bless you all,
Víctor Rafael Rivarola
