AjaxControlToolkit.ModalPopupExtender 不工作

Question

我正在开发 asp.net 项目，我添加了 AjaxControlToolkit，但总是出现错误。弹出窗口不工作，

                <asp:HiddenField ID="HiddenField1" runat="server" />
                <div class="panel" runat="server" id="DivConfirm">
                    <div class="panel-body" style="">

                                </asp:CommandField>
                            </Columns>

根据设计，AjaxControl-ModalPopup 必须以设计用于扩展的控件为目标。无法扩展隐藏字段，因为模态控件是为使用不同的控件列表而构建的；文本框、按钮等
