工作的HTML標記：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ChangeShiftStat.aspx.cs" Inherits="Default2" %> 
<!DOCTYPE html> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
    <title></title>

<body> 
    <form id="form1" runat="server">

&nbsp; New Status&nbsp;&nbsp;&nbsp; 
     <asp:DropDownList ID="DropDownList2" runat="server" AutoPostBack="True" DataSourceID="StatusDataSource" DataTextField="Status" DataValueField="Status">

      </SelectParameters>

C＃代碼：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 

public partial class Default2 : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
    } 
}
