我在这个模态弹出窗口上显示了模态弹出窗口（Modal2）我有网格包含链接按钮。在链接按钮的单击事件上，我必须显示另一个具有网格的模式弹出窗口。

我的第一个模态弹出窗口

<asp:Button ID="btnScholershipApp" runat="server" Text="Button" SkinID="SelectButton" />
        <Ajax:ModalPopupExtender ID="Modal2" runat="server" PopupControlID="table2" CancelControlID="img1"
            TargetControlID="btnScholershipApp" OnCancelScript="javascript:__doPostBack('clearfields2')">

试试这个，我在博客的某个地方读到，当我遇到这个问题时，如果我们没有以正确的顺序使用它们，在更新面板中使用 ModaloPopup Extender 会导致问题，就我而言，我发布的代码对我来说很好我也在更新面板中使用 ModalPopupExtender 尝试这个带有更新面板的 ModalPopupExtender 顺序，它肯定会起作用：

    <div class="popup">
            <asp:Button ID="Button7" runat="server" Text="Button" Style="display: none;" />
            <asp:Button ID="Button8" runat="server" Style="display: none;" />

            <asp:ModalPopupExtender ID="ModalPopupUploadFiles" BehaviorID="ModalPopupUploadFiles" runat="server" CancelControlID="ImageButton1"
                TargetControlID="Button7" PopupControlID="PanelUploadFiles" PopupDragHandleControlID="PopupHeader"
                Drag="true" BackgroundCssClass="Overlay">
                <Animations>         
                    <OnShown>
                        <FadeIn Duration=".50" Fps="10" />            
                    </OnShown>
                </Animations>
            </asp:ModalPopupExtender>
            <!--unique css-->
