在绑定窗体上显示特定行

我有一个表单直接与设计器创建的表适配器绑定。我还创建了一个列表框,其中包含每条记录的键值。我的想法是允许用户点击一个特定的键来在编辑屏幕中加载所需的记录。我可以在单击时访问列表条目,但不知道使用什么命令移动到正确的行。

我想知道是否真的值得使用这样的绑定表单,或者只是在代码中使用,类似于我创建列表框的方式。有什么建议吗?请参阅下面的代码:

public partial class Customer : Form
{
    public string dbConString = "Data Source=localhost\\BALLMILL;Initial Catalog=Ballmill;Integrated Security=True";
    public SqlConnection dbCon = null;
    public SqlDataReader dbRdr = null;
    public SqlCommand dbCommand = null;

    public Customer()
    {
        InitializeComponent();
    }
    private void cUSTOMERBindingNavigatorSaveItem_Click(object sender, EventArgs e)
    {
        this.Validate();
        this.cUSTOMERBindingSource.EndEdit();
        this.tableAdapterManager.UpdateAll(this.bML_WMS245GDataSet);
    }

    private void Customer_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'bML_WMS245GDataSet.CUSTOMER' table. You can move, or remove it, as needed.
        this.cUSTOMERTableAdapter.Fill(this.bML_WMS245GDataSet.CUSTOMER);

        SqlConnection dbCon = new SqlConnection(dbConString);
        SqlDataReader rdrCustomers = null;
        try
        {
            dbCon.Open();
            SqlCommand sqlCustomers = new SqlCommand("SELECT CustomerCode FROM Customer", dbCon);
            rdrCustomers = sqlCustomers.ExecuteReader();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message.ToString(), "Error accessing database");
            return;
        }

        while (rdrCustomers.Read())
        {
            listCustomers.Items.Add(rdrCustomers["CustomerCode"].ToString());
        }
    }

    private void listCustomers_SelectedIndexChanged(object sender, EventArgs e)
    {
        MessageBox.Show(listCustomers.SelectedItem.ToString(), listCustomers.SelectedIndex.ToString());
    }
}
