 I would assume that below example should do it but I could make
 it to work as well, at runtime, I receive the following error :

(<unknown>:2900): Gtk-CRITICAL **: gtk_tree_row_reference_new: assertion `GTK_IS
_TREE_MODEL (model)' failed

(<unknown>:2900): Gtk-CRITICAL **: gtk_tree_row_reference_new_proxy: assertion `
GTK_IS_TREE_MODEL (model)' failed

(<unknown>:2900): Gtk-CRITICAL **: gtk_cell_view_set_displayed_row: assertion `G
TK_IS_TREE_MODEL (cell_view->priv->model)' failed

 I guess my ComboBox is not properly initialized or something
 but did not find out the reason.

 Comments are welcome.

 Have a great day

(note:only relevant part of code given)

  [Glade.Widget] protected Gtk.ComboBox comboboxSeason = null;

  public void FillSeasonList()
  {
    // Remove all items from list
    comboboxSeason.Clear();

    int selectedSeason = 0;
    int currentPosition = 0;

    // Read database entries
    foreach (Season season in DbManager.getSeasons())
    {
      comboboxSeason.InsertText(currentPosition, season.Name);

      // Select the current season
      if (DateTime.Now >= season.StartDate && 
          DateTime.Now < season.StopDate)
      {
        selectedSeason = currentPosition;
      }

      currentPosition++;
    }

    // Select season
    comboboxSeason.Active = selectedSeason;
  }
