Answer 1

The simple and best solution [for me] would be to write a 'GotFocus' event and apply the Visibility on the required item.

    private void combobox_GotFocus_1(object sender, RoutedEventArgs e)
    {          
        var combobox = sender as ComboBox;

        if (combobox == null) return;
        var model = combobox.DataContext as Model;

        foreach (var item in combobox.ItemsSource)
        {
            if (item.Equals(model.Name))
            {
                var comboboxItem = combobox.ItemContainerGenerator.ContainerFromItem(item) as ComboBoxItem;
                if (comboboxItem != null)
                    comboboxItem.Visibility = Visibility.Collapsed;
            }
        }
    }
