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

Tue Dec 13 20:53:28 EST 2005

Hi,

Sorry Gennadiy, I meant the past few mails to go to the list.
Apparently, I must have hitted "Reply" instead of "Reply to All" and
didn't notice. Sorry for taking more of your time, but I am just
informing the list of whatever they missed.

I will keep on working on the example now. I also have limited time,
but my deadline is not so soon. Still, I really need this to allow me
to start on a project which is only missing this piece, as the code as
it stands now does not satisfy my needs.

God bless you all,

Víctor Rafael Rivarola
