我有一个用可折叠扩展器扩展的面板。它完美地工作，直到我尝试通过代码折叠它。

可折叠面板显示在模态弹出窗口内，用户搜索某些数据，即 在网格中显示，在每一行网格中都有一个选择按钮，用于触发网格的行命令事件，我试图关闭该面板。

                </td>
            </tr>
        </table>
    </asp:Panel>




    Code:
     protected void gvSearchResults_RowCommand(object sender, GridViewCommandEventArgs e)
            {
                if (e.CommandName == "Select")
                {
                     //some business logic
                    CollapsiblePanelExtender1.Collapsed = true;
                    ModalPopupExtender1.Show();
                }
            }

它不工作面板总是打开？任何建议......
