In this article we will bind records from database to a ListBox. Here we can bind only one column from the database. For that we have to mention the field name in DataTextField property of theListBox.

Imports System.Data
Imports System.Data.SqlClient
Partial Class _Default
Inherits System.Web.UI.Page
Dim strConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings.Item("ConnectionString").ToString()
Dim con As New SqlConnection(strConnString)
Dim str As String
Dim com As SqlCommand
Dim sqlda As SqlDataAdapter
Dim ds As DataSet
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) HandlesMe.Load
con.Open()
str = "select * from employee"
com = New SqlCommand(str, con)
sqlda = New SqlDataAdapter(com)
ds = New DataSet
sqlda.Fill(ds, "employee")
ListBox1.DataValueField = "empid"
ListBox1.DataTextField = "empname"
ListBox1.DataSource = ds
ListBox1.DataMember = "employee"
ListBox1.DataBind()
con.Close()
End Sub
End Class

Output

Here we have field name as empname in DataTextField property of the ListBox.
