Check Monodoc I think what you are looking for should be in the sample code
in the overview section.  It's also located in the web version of the
documentation at http://www.go-mono.com/docs/ under Gnome
Libraries->Gtk->ComboBox Class.  Just in case you cannot access the web
documentation (but somehow able to read email...), or access/build Monodoc,
I've pasted the sample code from said documentation below...

using System;
using Gtk;

class ComboBoxSample
{
     static void Main ()
     {
          new ComboBoxSample ();
     }

     ComboBoxSample ()
     {
          Application.Init ();

          Window win = new Window ("ComboBoxSample");
          win.DeleteEvent += new DeleteEventHandler (OnWinDelete);

          ComboBox combo = ComboBox.NewText ();
          for (int i = 0; i < 5; i ++)
               combo.AppendText ("item " + i);
          combo.Changed += new EventHandler (OnComboBoxChanged);

          win.Add (combo);

          win.ShowAll ();
          Application.Run ();
     }

     void OnComboBoxChanged (object o, EventArgs args)
     {
          ComboBox combo = o as ComboBox;
          if (o == null)
               return;

          TreeIter iter;

          if (combo.GetActiveIter (out iter))
               Console.WriteLine ((string) combo.Model.GetValue (iter, 0));
     }

     void OnWinDelete (object obj, DeleteEventArgs args)
     {
          Application.Quit ();
     }
}

Thanks.
