Adding values to the valuemember of a combobox

friends,

I am trying a new method of getting data (OSD's) and I am having trouble getting the valuemember added to the combobox that I am trying to populate.

Here is where I am tryting to populate it:

    Public Sub ProcessCarList(ByVal RunID As Integer)
        Try
            frmMain.cmbPickACar.Items.Clear()

            Using TableAdapter As New dsPenalizedCarTableAdapters.CarNumberListTableAdapter
                Using DataTable As dsPenalizedCar.CarNumbersDataTable = TableAdapter.GetData(RunID)
                    Dim Row As dsPenalizedCar.CarNumbersRow
                    For Each Row In DataTable
                        frmMain.cmbPickACar.Items.Add(Row.CarNumber)
                        frmMain.cmbPickACar.ValueMember = (Row.ResultID)
                    Next
                End Using
            End Using
        Catch ex As Exception

        End Try

    End Sub

Now, when I click the combobox, I see all the car numbers listed; however, if I try to use the value portion of the combobox, there is nothing in it.

    Private Sub cmbPickACar_DropDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbPickACar.DropDown
        Dim HandleCars As New HandleCarList
        HandleCars.ProcessCarList(RunID)
    End Sub

    Private Sub cmbPickACar_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbPickACar.SelectedIndexChanged
        Dim ResultItemIDToUse As String = ""

        If cmbPickACar.SelectedIndex <> -1 Then
            ResultItemIDToUse = cmbPickACar.SelectedValue
            MessageBox.Show(ResultItemIDToUse)
        End If

    End Sub

What am I doing wrong?

Thanks in advance!
