<head>

    <script runat="server">

        Sub ItemsBulletedList_Click(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.BulletedListEventArgs)
            ' Change the message displayed in the label based on the index
            ' of the list item that was clicked.
            Select Case (e.Index)
                Case 0
                    Message.Text = "You clicked list item 1."
                Case 1
                    Message.Text = "You clicked list item 2."
                Case 2
                    Message.Text = "You clicked list item 3."
