ValueMember wrong in DataGridViewComboBoxColumn

Question

The class below is the data source for the combo of datagridview:

public class Customer
{
    public int Id { get; set; }

    public string Name { get; set; }

    public string City { get; set; }
}

The next is the data source for the datagridview:

public class Order
{
    public int Id { get; set; }

    public int IdCustomer { get; set; }

    public DateTime RequestDate { get; set; }
}

For simplicity, I will carry them with fixed values, but similar to my real case:

private void Form1_Load(object sender, EventArgs e)
    {
        bdsCustomer.DataSource = new List<Customer>
                                     {
                                         new Customer {Id = 1, Name = "Paulo", City = "City A"},
                                         new Customer {Id = 2, Name = "Tatiane", City = "City B"},
                                         new Customer {Id = 3, Name = "Paulo", City = "City C"},
                                     };

        bdsOrder.DataSource = new List<Order>
                                  {
                                      new Order {Id = 1, IdCustomer = 1, RequestDate = new DateTime(2015, 8, 25)},
                                      new Order {Id = 2, IdCustomer = 2, RequestDate = new DateTime(2015, 8, 26)},
                                      new Order {Id = 3, IdCustomer = 3, RequestDate = new DateTime(2015, 8, 27)}
                                  };


    }

I'll let the field "IdCustomer" in datagridview to display the problem and I'll create a new field with the combo:

Notice in the image that the "IdCustomer" field of the first record is correct and presenting the Id 1:

Now I will select the other "Paul" with the Id 3 and see what happens to the value of IdCustomer:

Even selecting the client with the Id 3, the Id continues 1. You can have 10 clients "Paul", anyone who select the IdCustomer does not change.

What can I do?

I solved the problem, I used the DevExpress grid, is now working perfectly!
