我在我的单个 .aspx 页面中使用了两个弹出扩展器，这两个都没有弹出，但是当我删除这两个中的任何一个时，一个弹出很好。

<asp:Button ID="btnShowPopup" runat="server" style="display:none" /> 
<asp:Button ID="btnshowpopupisbn" runat="server" style="display:none" />  

<asp:ModalPopupExtender ID="ModalPopupExtender1"     runat="server"TargetControlID="btnShowPopup" PopupControlID="pnlpopup"
CancelControlID="btnCancel" BackgroundCssClass="modalBackground"     PopupDragHandleControlID="pnlpopup" >
    </asp:ModalPopupExtender>   
 <asp:Panel ID="pnlpopup" runat="server" CssClass="popup" >
 <asp:UpdatePanel ID="UpdatePanel1" runat="server">
 <ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>

 <asp:ModalPopupExtender ID="ModalPopupExtender2" runat="server"       TargetControlID="btnshowpopupisbn" PopupControlID="pnlpopupisbn"   cancelControlID="btnCancel" BackgroundCssClass="modalBackground"    PopupDragHandleControlID="pnlpopup"></asp:ModalPopupExtender>
<asp:Panel ID="pnlpopupisbn" runat="server" CssClass="popup" Visible="False" >
<asp:UpdatePanel ID="UpdatePanel2" runat="server">


 <ContentTemplate>
 </ContentTemplate>
</asp:UpdatePanel> 
</asp:Panel>

不要将属性 visible 设置为 false 。将其设置为 true

您不需要Visible="False"在面板上提供属性，当您使用 ModalPopupExtender 时会处理它。我刚刚尝试使用 2 个模式弹出窗口，效果很好。

<div>
        <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
        </asp:ToolkitScriptManager>
        <asp:Button ID="Button1" runat="server" Text="Popup 1" />
        <asp:ModalPopupExtender ID="ModalPopupExtender2" runat="server" PopupControlID="Panel1"
            TargetControlID="Button1" OkControlID="Button2" BackgroundCssClass="ModalPopupBG">
        </asp:ModalPopupExtender>
        <asp:Panel ID="Panel1" runat="server" CssClass="popup">
            Some Content in Panel 1<br />
            <asp:Button ID="Button2" runat="server" Text="Close" />
        </asp:Panel>
        <asp:Button ID="Button3" runat="server" Text="Popup 2" />
        <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Panel2"
            TargetControlID="Button3" OkControlID="Button4" BackgroundCssClass="ModalPopupBG">
        </asp:ModalPopupExtender>
        <asp:Panel ID="Panel2" runat="server" CssClass="popup">
            Some Content in Panel 2<br />
            <asp:Button ID="Button4" runat="server" Text="Close" />
        </asp:Panel>
    </div>

你可以做 Panel Visible="False"
