下面的实例显示了多个被选中的复选框项目：

   <script runat="server">
   Sub ClickCheck(sender As Object, e As EventArgs)
     lbl1.Text = "Selected Item(s):<br />"
     Dim i As Integer
     For i = 0 To cb1.Items.Count - 1
       If cb1.Items(i).Selected Then
         lbl1.Text = lbl1.Text & cb1.Items(i).Text & "<br />"
       End If
     Next
   End Sub
   </script>
  
   <form method="post" runat="server">
   <asp:CheckBoxList id="cb1" AutoPostBack="True"
   OnSelectedIndexChanged="ClickCheck" runat="server">
     <asp:ListItem Value="Item 1" />
     <asp:ListItem Value="Item 2" />
     <asp:ListItem Value="Item 3" />
     <asp:ListItem Value="Item 4" />
