Data Bind、DataMember 和 DataSource 不是 OleDb 的成员

DataBind, DataMember and DataSource is not a memeber of OleDb

我有一个下拉列表,其中填写了我的 oracle 数据库中所有 50 个州的缩写。

我很困惑为什么我的编码会标记以下错误:

我在另一个应用程序中使用了这个确切的编码;但是,这个标记了错误。有什么建议吗?

Imports System
Imports System.IO
Imports System.Data
Imports System.Data.OleDb
Imports System.Text
Imports System.Security.Principal

Public Class SuppUpdate
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Not IsPostBack Then
        If Not States Is Nothing Then

            Dim conn As OleDbConnection = New OleDbConnection("Provider=""*****"";user id=" & strUserID & ";data source=" & strDatabase & ";password=" & strPssWd)

            Dim SupplierState As OleDbCommand = New OleDbCommand("SELECT column_name FROM table_name order by column_name", conn)
            Dim OracleDataAdapterAds1 As OleDbDataAdapter = New OleDbDataAdapter
            OracleDataAdapterAds1.SelectCommand = SupplierState
            Dim DsAds As DataSet = New DataSet
            DsAds.Clear()
            conn.Open()
            If Not (DsAds Is Nothing) Then
                OracleDataAdapterAds1.Fill(DsAds, "table_name")
                SupplierState.DataSource = DsAds
                SupplierState.DataMember = "table_name"
                SupplierState.DataBind()
            End If

        End If
        End If
End Sub

更新:对我的数据源(下拉列表的 ID)进行了更正,但它的填充方式如下:

If Not StatesList Is Nothing Then

            Dim conn As OleDbConnection = New OleDbConnection("Provider=""****"";user id=" & strUserID & ";data source=" & strDatabase & ";password=" & strPssWd)

            Dim SupplierState As OleDbCommand = New OleDbCommand("SELECT column FROM table order by column", conn)
            Dim OracleDataAdapterAds1 As OleDbDataAdapter = New OleDbDataAdapter
            OracleDataAdapterAds1.SelectCommand = SupplierState
            Dim DsAds As DataSet = New DataSet
            DsAds.Clear()

            If Not (DsAds Is Nothing) Then
                OracleDataAdapterAds1.Fill(DsAds, "table")
                StatesList.DataSource = DsAds
                StatesList.DataMember = "table"
                StatesList.DataBind()
            End If
 End if

错过了 html 中的 DataValueField = "column"

另外...DataBind、DataMember 和 DataSource 应该使用下拉列表 ID。
