Posting this answer because the OP requested it.

This is how you would do that in WPF:

Code Behind:

public partial class ListBoxInCell : Window
{
    public ViewModel ViewModel { get; set; }

    public ListBoxInCell()
    {
        InitializeComponent();

        DataContext = ViewModel = new ViewModel();
    }

    private void ShowDetail(object sender, RoutedEventArgs e)
    {
        MessageBox.Show(ViewModel.SelectedItem.SelectedDetail);
    }
}

ViewModel:

public class ViewModel
{
    public List Items { get; set; }

    public Data SelectedItem { get; set; }

    public ViewModel()
    {
        //Sample Data
        Items = Enumerable.Range(0, 100).Select(x => new Data
            {
                Product = "Product" + x.ToString(),
                Details = Enumerable.Range(0, 3)
                                    .Select(d => "Detail" + x.ToString() + "-" + d.ToString())
                                    .ToList()
            }).ToList();
        SelectedItem = Items.First();
    }
}

Data Item:

public class Data
{
    public string Product { get; set; }

    public List Details { get; set; } 

    public string SelectedDetail { get; set; }
}

Result:

• MVVM, which means data is separate from UI and UI is separate from data.
• No "owner draw", no "P/Invoke" (whatever that means), and no horrible procedural hacks. Only beautiful XAML and DataBinding.
• The selection of each ListBox inside each row is indiviual, you may want to keep only 1 selected Item by setting all the others to null with a simple LINQ query and an iteration.
• click on the button to see the currently selected Detail for the currently selected Row in the ListView.
• WPF Rocks, copy and paste my code in a File -> New Project -> WPF Application and see the results for yourself.
• Forget winforms. It's useless. It doesn't support any level of customization and requires a lot of horrible hacks for everything. It doesn't support (real) DataBinding and forces you into a boring procedural approach.
