                                                            </tr>
                                                                                                                                                                                  <tr>
                                                                <td style="width: 100%;">
                                                                </td>
                                                            </tr>
                                                        </table>
                                                    </td>
                                                </tr>
                                            </asp:Panel>

把panel用enable=false禁用后,里面的所有控件都变灰了,想问一下有没有里面的控件不可用,但是不变灰的办法,因为灰色实在太难看清楚了! --------------------编程问答-------------------- 你可以设置panel不可用的时候，同时设置他的css属性，换个别的颜色即可！ --------------------编程问答-------------------- 能说的更详细些吗?
