To fix this issue Put your code in SelectionChangeCommitted Instead of SelectedIndexChanged
code :
private void comboBox1_SelectionChangeCommitted(object sender, EventArgs e)
{
    FillDropDownList("select StateCode,StateName from States Where CountryCode = '" + comboBox1.SelectedValue + "'", comboBox2, "StateCode", "StateName");
}

may help you . You should set the ValueMember of Combobox1 to be the ID you retrieved from the database and the use the SelectedValue property to retrieve the ID of the selected item.
I don't think it's gonna work unless you specify the ValueMember property when you databind Combobox1, so don't forget to do that first.
code :
Public Sub New()

    ' This call is required by the designer.
    InitializeComponent()

    ' Add any initialization after the InitializeComponent() call.

    Dim ds As New DataSet()
    Dim test As New OleDbDataAdapter("SELECT [ID], [名前] FROM [Tレイヤ管理]", DBConnections.PrimaryAccessDBConnection)
    Call test.Fill(ds, "testTable")

    Me.ComboBox1.DataSource = ds.Tables("testTable")
    Me.ComboBox1.ValueMember = "ID"
    Me.ComboBox1.DisplayMember = "名前"

    AddHandler Me.ComboBox1.SelectedValueChanged, AddressOf Something

End Sub

Private Sub Something(sender As Object, e As EventArgs)

    Call MessageBox.Show(String.Format("ID {0}", Me.ComboBox1.SelectedValue))

End Sub
    Dim selectedItem As DataRowView = CType(Me.ComboBox1.SelectedItem, DataRowView)

    Call MessageBox.Show(String.Format("ID {0} Name {1}", New Object() {selectedItem("ID"), selectedItem("名前")}))

End Sub
