[vb.net window app]ทำยังไงอ่ะครับ ทำ dropdownโดยดึงจาก Database มาให้โชว์ข้อมูลทั้งรายละเอียดและลำดับที่

 Me.DataTable1TableAdapter.Fill(Me.PlannedITEquip.DataTable1)
            Dim objConn As New OleDbConnection
        Dim objCmd As OleDbCommand
        Dim dtAdapter As New OleDbDataAdapter

        Dim ds As New DataSet
        Dim dt As DataTable
        Dim strConnString, strSQL As String

        strConnString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\paweenawat\Documents\Visual Studio 2010\Visual Studio 2010\Projects\PMCBL\PMCBL\PMCBL\PMCBL\PMCBL\PMCBL\PMCBL\PMCBL_ITINV_V0.8.accdb"
        'objConn = New OleDbConnection(strConnString)
        objConn.ConnectionString = strConnString
        objConn.Open()
        strSQL = "SELECT * FROM IT_Description order by ItemNo asc"
        objCmd = New OleDbCommand
        With objCmd
            .Connection = objConn
            .CommandText = strSQL
            .CommandType = CommandType.Text
        End With
        dtAdapter.SelectCommand = objCmd

        dtAdapter.Fill(ds)
        dt = ds.Tables(0)

        dtAdapter = Nothing
        objConn.Close()
        objConn = Nothing

        txtItemNo.DataSource = dt
        txtItemNo.DisplayMember = "ItemNo"
        txtItemNo.DisplayMember = "Item_Desc"
        txtItemNo.ValueMember = "ItemNo"
