This sample might help you in understanding how listbox can be used.

public class Employee
{
    public string Name { get; set; }
    public string Gender { get; set; }        
}

XAML

<StackPanel>
  <DataGrid AutoGenerateColumns="False" Name="myGrid" Margin="10">
     <DataGrid.Columns>
        <DataGridTextColumn Binding="{Binding Path=Name}" />             
        <DataGridComboBoxColumn Width="100" x:Name="Gender" 
                    SelectedValueBinding="{Binding Gender, Mode=TwoWay}"  
                    DisplayMemberPath="{Binding Gender}" />
     </DataGrid.Columns>
  </DataGrid>
  <Button Name="ShowPersonDetails"  
          Content="Show Person Details" 
          Width="200" Height="30"  
          Click="ShowPersonDetails_Click" Margin="10" />
</StackPanel>

Code-behind

public partial class WPFDataGridComboBox : Window
{
    public List<Employee> Employees { get; set; }
    public List<string> Genders { get; set; }

    public WPFDataGridComboBox()
    {
        Employees = new List<Employee>()
        {
            new Employee() { Name = "ABC", Gender = "Female" },
            new Employee() { Name = "XYZ" }
        };

        Genders = new List<string>();
        Genders.Add("Male");
        Genders.Add("Female");

        InitializeComponent();
        myGrid.ItemsSource = Employees;
        Gender.ItemsSource = Genders;
    }

    private void ShowPersonDetails_Click(object sender, RoutedEventArgs e)
    {
        foreach (Employee employee in Employees)
        {
            string text = string.Empty;
            text = "Name : " + employee.Name + Environment.NewLine;
            text += "Gender : " + employee.Gender + Environment.NewLine;
            MessageBox.Show(text);
        }
    }
}
