推荐答案

我认为你的更新面板需要一个触发器。目标控件ID应该是上传文件的按钮。

I think you need a trigger for your update panel. The target control id should be the button that uploads the file.

<asp:UpdatePanel runat="server">
        <ContentTemplate>
//Your code in here with btnUploader
                   </ContentTemplate>
<Triggers>
    <asp:PostBackTrigger ControlID="btnUploader" />
</Triggers>
    </asp:UpdatePanel>
