                                                    </table>
                                                </ContentTemplate>
                                            </asp:UpdatePanel>
                                        </asp:Panel>

我想要它的scollbar。

我提到How can I make the modal popup scroll its contents with the page?并将css设为：

.modalBackground 
{
    overflow : auto ;
    background-color:Black ;
    filter:alpha(opacity=65);
    -moz-opacity:0.65;                     
    Opacity:0.65; 
}

但仍然没有滚动条，（我还提到了Height =“500px”面板。

请帮帮我。

Answer 1

您可以将面板内容包含在具有max-height和overflow：auto

的div中

<asp:Panel ID="PnlUpdate" runat="server" Width="500px" CssClass="popup" Height="500px" >
    <div id="Div1" runat="server" style="max-height: 500px; overflow: auto;">

        PANEL CONTENTS 

    </div>
</asp:Panel>

Answer 2

您应该将CSS属性提供给'popup'css类。使用下面给出的类

.popup {overflow : auto ; height: 500px; }

modalpopup扩展器的滚动条
