Win App C# อยากทำ usercontrol ให้มีตัวเลือก DataSource DisplayMember ValueMember เหมือน combobox

Sub LoadChart
  OpenDatabase()
        Dim strSQL6 As String = "SELECT ac_cd AS 'รหัส', ac_nm AS 'ชื่อ ภาษาไทย', ac_nme AS 'ชื่อ ภาษาอังกฤษ' FROM Sacc_Chart"
        Dim da6 As New SqlDataAdapter(strSQL6, Connt)
        Dim ds6 As New DataSet
        da6.Fill(ds6, "Sacc_Chart")
        With cb_ac_code.Properties
            .DataSource = ds6.Tables("Sacc_Chart")
            .DisplayMember = "รหัส"
            .ValueMember = "รหัส"
        End With
End Sub

this.textbox2AndButton2.DataSource = this.pOSTCODEDataSet.PostCode_Province;
this.textbox2AndButton2.DisplayMember = "Post_Amphur";
this.textbox2AndButton2.ValueMember = "Post_Amphur_ID";
