[Gtk-sharp-list] DataGrid control, data binding, ObjectViews, Swf, Gtk

Tue Dec 13 13:02:31 EST 2005

Daniel, Geennadiy:

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
