Asp.Net Ajax 工具包 AsyncFileUpload - "The file is attached is invalid"错误

我正在尝试使用 Asp.net Ajax Control Toolkit 中的 AsyncFileUpload 控件(2009 年 9 月 30 日稳定版本:30930)。我创建了一个演示应用程序,并且控件工作正常。文件上传,一切顺利。

当我尝试在实际应用程序中使用该控件时,我总是收到一条错误消息,指出“附加的文件无效”。当上传的文件为空时,AsyncFileUpload 控件返回此值。

为了隔离问题,我创建了一个与演示应用程序中的母版页完全相同的新母版页。我还创建了一个与我的演示应用程序中的页面完全相同的 aspx 页面。上传仍然失败,并出现“附加的文件无效”错误。

我还比较了真实应用程序和演示应用程序的 web.config,但无法识别任何重要的差异。

下面的代码是我真实应用程序中的测试代码。此代码与演示应用程序中的功能代码完全相同,只是类名和文件名不同。下面列出的 web.config 来自真实应用程序,删除了应用程序设置和连接字符串。

此时此刻,我彻底陷入了困境。

真实应用测试母版页:

编辑:我不再为这家公司工作,因此我无法测试任何新答案以查看它们是否解决了问题。

最佳答案

我在 .NET 4 中遇到了同样的问题。我通过在控件上设置 ClientIDMode="AutoID"来解决它。

关于Asp.Net Ajax 工具包 AsyncFileUpload - "The file is attached is invalid"错误,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/2314450/
