[gnome-db] getting GnomeDb widgets from Glade

[Marius Andreiana <mandreiana rdslink ro>]

Hi

In C#, I'm trying to get a reference to gnomedb widgets from Glade:

Glade.XML gui;
GnomeDb.Grid db_grid;
Gtk.VBox vbox_main;

gui = new Glade.XML( null, "../gui/test.glade", "application", null );
gui.Autoconnect( this );
db_grid = (GnomeDb.Grid)gui.GetWidget( "db_grid" ) ;

//this works
vbox_main = (Gtk.VBox)gui.GetWidget( "vbox_main" ) ;

Error is:
Unhandled Exception: System.InvalidCastException: Cannot cast from
source type to destination type

How can I use gnomedb widgets in glade  like the rest?

Thanks
