[Mono-dev] DataList SelectedIndex

The selectedIndex of the DataList control always return -1, when I run the following test code under mono-1.1.17. Same code works fine in .NET.
Is this a bug or just this coding can't get the selectedIndex under Mono?
Any help is appreciated.


<%@ Page Language="C#" %>

<p>Test DataList Select</p>
<form id="x" runat="server">
<asp:DataList id="DataList1" runat="server" EnableViewState="true" OnSelectedIndexChanged="dl_OnSelectedIndexChanged">
       <td><asp:button id="selectButton" CommandName="Select" runat="server"/></td>
        <%# ((DictionaryEntry)Container.DataItem).Key %>&nbsp;
        <%# ((DictionaryEntry)Container.DataItem).Value %> 
<asp:Label ID="label1" runat="server" />

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
        if (!Page.IsPostBack)
        Hashtable ht = new Hashtable();
        ht.Add ("test1", "A");
        ht.Add ("test2", "B");
        ht.Add ("test3", "C"); 
        DataList1.DataSource = ht;

    protected void dl_OnSelectedIndexChanged(object sender, EventArgs e)
        this.Response.Output.WriteLine("The method dl_OnSelectedIndexChanged is called.");
        label1.Text = "DataList1.SelectedIndex = " + DataList1.SelectedIndex;
