Visual Basic:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Introducir aquí el código de usuario para inicializar la página
If Not IsPostBack Then
ListBox1.Items.Add(New System.Web.UI.WebControls.ListItem("Uno", 10))
ListBox1.Items.Add(New System.Web.UI.WebControls.ListItem("Dos", 20))
ListBox1.Items.Add(New System.Web.UI.WebControls.ListItem("Tres", 30))
ListBox2.Items.Add(New System.Web.UI.WebControls.ListItem("Cien", 100))
ListBox2.Items.Add(New System.Web.UI.WebControls.ListItem("Doscientos", 200))
ListBox2.Items.Add(New System.Web.UI.WebControls.ListItem("Trescientos", 300))
End If
Button1.Attributes.Add("onclick", "javascript:return pasaraderecha();")
Button2.Attributes.Add("onclick", "javascript:return pasaraizquierda();")
