Question

当我点击一个 but子时,我试图在我的网页上使用一个模式的流行延伸器,我必须显示一个小组。在这方面,我已经:

    <asp:UpdatePanel runat="server" ID="updPanel">
    <ContentTemplate>
        <ajaxToolkit:ModalPopupExtender ID="mpeEmailComplete" runat="server" TargetControlID="btnTesting"
            PopupControlID="pnl" OkControlID="btnOk"
             BackgroundCssClass="modalBackground">
        </ajaxToolkit:ModalPopupExtender>



        <asp:Panel ID="pnl" runat="server" style="display:none;">
            <asp:UpdatePanel ID="udp" runat="server">
                <ContentTemplate>
                    <asp:Panel runat="server" ID="pnlEmailComplete" Visible="false">
                        <asp:Label runat="server" ID="lblTest" Text="Testing testing testing"></asp:Label>
                        <asp:Button runat="server" ID="btnOk" Text="OK" />
                    </asp:Panel>
                </ContentTemplate>
            </asp:UpdatePanel>
        </asp:Panel>


        <asp:Button runat="server" ID="btnTesting" Text="Testing"/>

    </ContentTemplate>
</asp:UpdatePanel>

但是,当纽特被点击时,可以让小组坐下来。任何人都知道为什么?

Answer 1

你的内心小组有可见的=。

<asp:Panel runat="server" ID="pnlEmailComplete" Visible="false">  *(change here)*

因此,当你发布TESating button时,ModalPopupExtender正确地使外部小组展示,但显示一个看不见的内部小组,因此你看不到任何屏幕。

<asp:Panel ID="pnl" runat="server" style="display:none;">  *(this is ok)*

To fix, just yank the Visible=false from the outer panel (pnlEmailComplete)

Hope that helps!

Answer 2

页: 1 Visible=False; set on the Service-side any处?

确保有<代码>。适当参考的AjaxControlToolkit,NuGet是添加该参考内容的最容易的方法。
