Question

This is probably classic noob question but Im really new to C# (Windows Forms App), and I would appreciate any help on this. So, Im looking for the way to do this:
I have one list box with items that represent database table entries. I want to delete a row in database table by deleting list box item. Is there any way to assign value to list box item (primary key for example) so I could use it to update db table when deleting list box item?

Thanks for your time!

EDIT: Its Db4o database.

If you want to do it manually:

public class MyDBRecord
{
    public int ID { get; set; } 
    public string Text { get; set; }
    public MyDBRecord(int _id, string _text)
    {
        ID = _id;
        Text = _text;
    }
}
private void button1_Click(object sender, EventArgs e)
{
    listBox1.DisplayMember = "Text";
    listBox1.ValueMember = "ID";

    listBox1.Items.Add(new MyDBRecord(1, "abc"));
    listBox1.Items.Add(new MyDBRecord(2, "def"));
    listBox1.Items.Add(new MyDBRecord(3, "hij"));
}

private void button2_Click(object sender, EventArgs e)
{
    MyDBRecord Selected;

    Selected = listBox1.SelectedItem as MyDBRecord;

    if (Selected != null)
        MessageBox.Show(Selected.ID.ToString());     
}
