我在我的单个.aspx页中使用了两个弹出扩展程序，但是两个都没有弹出，但是当我删除两个中的任何一个时，都可以正常弹出。

<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>

最佳答案

您可以执行Panel Visible =“ False”
