I have a dropdown list that fills in with the abbreviation of all 50 states from my oracle database.
I am confused why my coding is flagging the following errors:
I have used this exact coding in another application; however, this one flags the error. Any suggestions?
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
UPDATE: made the correction to my DataSource (id of dropdown list) but it fills like so:
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
Missed the DataValueField = "column"
in the html.
Plus... the DataBind, DataMember and DataSource should use dropdownlist ID.
