关于DataList分页的问题，拜托帮我看看！！
页面代码：
<asp:DataList ID="DataList1" runat="server" Width="668px" CellSpacing="3" DataSourceID="SqlDataSource1" pagesize="3">
  <ItemTemplate>
  <div class="mainBox" style="width:660px; height:100px; border:solid 2px; border-color:Blue;">
  <div class="leftBox" style="width:20%; height:100px; border-right:solid 2px; border-right-color:Blue; float:left; text-align:center;">
  <asp:Image ID="Image1" runat="server" Width="78px" Height="80px" Text='<%# Eval("facing","~/images/.jpg") %>' /><br />
  <asp:Label ID="nameLabel" runat="server" Text='<%# Eval("name") %>'></asp:Label>
  </div>
  <div class="rightBox" style=" height:100px; float:left;">
  标题：
  <asp:Label ID="titleLabel" runat="server" Text='<%# Eval("title") %>'></asp:Label><br />
  <asp:Label ID="wdateLabel" runat="server" Text='<%# Eval("wdate") %>'></asp:Label><br />
  <asp:Label ID="messageLabel" runat="server" Text='<%# Eval("message") %>'></asp:Label><br />
  回复：
  <asp:Label ID="re_messageLabel" runat="server" Text='<%# Eval("re_message") %>'></asp:Label><br />
  </div>
  </div>
  </ItemTemplate>
  <FooterTemplate>
  <table width="660px">
  <tr>
  <td style="width:120px;" align="center">
  <asp:Label ID="lblCurPage" runat="server" Text="Label"></asp:Label>
  </td>
  <td style="width:540px;">
  <asp:HyperLink ID="lnkFirst" runat="server">第一页</asp:HyperLink>
  <asp:HyperLink ID="lnkPrev" runat="server">上一页</asp:HyperLink>

  <asp:HyperLink ID="lnkLast" runat="server">最后一页</asp:HyperLink>
  </td>
  </tr>
  </table>
  </FooterTemplate>
  </asp:DataList>
  <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyDataBaseConnectionString %>" SelectCommand="SELECT [name], [title], [message], [wdate], [re_message] FROM [Message] ORDER BY [wdate] DESC"></asp:SqlDataSource>
