Default Issue Binding to ComboBox.

Dear Friends,

Please help me solve this problem(see source code on flollowing): When form load, in combo box will have 3 items with description what I would. But when I click Select button to show it's value then it will return: "ExamID" is the same with property that I assign for it while bind data.
For Example:
DisplayMember: Exam 1, Exam2 ,...OK
ValueMember: "ExamID" string. what I need: 1,2,...

I tried but I could not debug this problem.

Please help me....

Thank you very much


Private Sub BindData()

   Dim conn As New OleDbConnection(DbObject.CONNECTION_STRING)
   Dim cmd As New OleDbCommand("SELECT ExamID, Description FROM ExamEN", conn)
   Dim adapter As New OleDbDataAdapter(cmd)
   Dim ds As New DataSet

   adapter.Fill(ds, "Exam")

   With listExam
      .ValueMember = "ExamID"
      .DisplayMember = "Description"
      .DataSource = ds.Tables("Exam")
   End With

End Sub

Private Sub SelectExam_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   'Bind data to combobox
End Sub

Private Sub btnSelect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSelect.Click

   Dim str As String

   str = Me.listExam.ValueMember

End Sub
