DataBind，DataMember和DataSource不是OleDb的成员

Question

我有一个下拉列表，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，这个标志着错误。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DataSource（下拉列表的ID）进行了更正，但它填充如下：

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

Answer 1

错过了html中的DataValueField = "column"。

Plus ... DataBind，DataMember和DataSource应使用下拉列表ID。
