                PopupControlID="panel" DropShadow="true"
                BackgroundCssClass="modalBackground/>

推荐答案

如果您阅读了ModalPopup [

If you read the documentation for ModalPopup[^] you will understand what is happening.
TargetControlID - The ID of the element that activates the modal popup.

If you look at the documentation you will see a sample for activating the ModalPopup from server-side code.

因此您的弹出窗口正在显示，但C#代码似乎未在执行?也许尝试删除 targetcontrolid ="save1" .我猜想模态弹出窗口正在拦截click事件，因此可以防止回发(因此您的C#代码未运行).如果删除了该代码，但保留了 MPE.Show()，则应在C#运行后弹出模式.

So your popup is showing, but the C# code doesn''t appear to be executing? Perhaps try removing targetcontrolid="save1". I am guessing that the modal popup is intercepting the click event and so is prevent a postback (so your C# code isn''t running). If you remove that, but keep the MPE.Show(), then the modal should popup after your C# runs.
