Microsoft JScript运行时错误:'clientUploadComplete'未定义

我的用户控制代码抛出javascript错误。

如果我没有在主页中包含uplNewRequestCreation，那么一切都会按预期进行。所有服务器端和客户端文件上传功能都会被触发。在主页中包含更新面板的原因是为了避免整页回发。

我尝试了几种来自在线资源的解决方案，但都无济于事。

1. 已将scriptmanagerpoxy添加到用户控制页
2. 在pageload后面的代码中定义了javascript-这个解决方案有效，但没有触发OnUploadedComplete="uplFile1_Uploadedcomplet"
3. 将文件上传用户控件添加为主更新面板的触发器，并将更新模式更改为条件

错误消息：初始化FileUpload.ascx.cs后，将显示以下错误消息。Microsoft JScript运行时错误："clientUploadComplete"是未定义的

我非常感谢你的帮助！

谢谢！！！！

这是我的代码结构。
