ASPX页面上下分栏问题

Question

 

项目是C#.NET开发的。我需要的页面效果是把一个页面分成上下2部分。

上面部分是不会动的，在上面部分有一个DROPDOWNLIST根据我

选择的DROPDOWNLIST值，页面的下面部分发生变化。

现在的ASPX页面全是DIV写的。

如下:

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

 <div class="contents-area">
                <div class="tabledata">
                    <!-- Group Direct↓↓ -->
                    <h3>
                        <asp:Label ID="lblIdGroupAddressBook" runat="server" Text="Address Book"></asp:Label>
                    </h3>
                    <asp:UpdatePanel ID="udpIdGroupAddBookList" runat="server">
                        <ContentTemplate>
                    <table cellpadding="0" cellspacing="2" id="TABLE8" runat="server">
                        <tr>
                            <td>
                               <div class="left">
                                    <asp:ImageButton ID="btnIdGroupAddress_SelAll" runat="server" />
                                </div>
                               <div class="right">
                                    <UserControlerPage ID="PerPageControl" runat="server" />
                               </div>
                                <div class="tabledata">
                                    <asp:table cellpadding="0" cellspacing="2" ID="GroupAddressBookListTable" runat="server">
                                    </asp:table>
                                </div>
                            </td>
                        </tr>
                    </table>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                    <!-- Group Direct↓↓ -->
                </div>
            </div>
