用AJAX这个可以不<asp:UpdatePanel ID="upl" runat="server" UpdateMode="Conditional">
                        <ContentTemplate>
                           <asp:UpdateProgress ID="UpdateProgress1" runat="server">
                                <ProgressTemplate>
                                  <div class="wopen2">
                                    <div align="center" class="login font_04">数据加载中，请等待……</div>
                                    </div>
                                </ProgressTemplate>
                            </asp:UpdateProgress>
