Asp.Net Ajax 工具包 AsyncFileUpload - “附加的文件无效”错误

发布于 2024-08-22 11:52:23 字数 15204 浏览 6 评论 0原文

我正在尝试使用 Asp.net Ajax Control Toolkit (2009 年 9 月 30 日稳定版本：30930) 中的 AsyncFileUpload 控件。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，我创建了一个新的母版页，与演示应用程序中的母版页完全相同。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，并显示“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 来自真实的应用程序，其中删除了应用程序设置和连接字符串。

此刻，我完全被难住了。

编辑： 我不再为这家公司工作，所以我无法测试任何新答案以查看它们是否修复了问题。

原文

I'm trying to use the AsyncFileUpload control from the Asp.net Ajax Control Toolkit (Sept 30, 2009 stable build: 30930) . I've created a demo application and the control works fine. Files upload and all is well.

When I try to use the control in my real application, I'm always receiving an error stating "The file attached is invalid". The AsyncFileUpload control returns this when the file uploaded is null.

To isolate the problem, I created a new master page exactly like the master page in my demo app. I also created an aspx page exactly like the page in my demo app. The upload still fails with a "The file attached is invalid" error.

I also compared the web.config for the real app and the demo app and couldn't identify any differences that should matter.

The code below is the test code in my real app. This code is exactly the same as the functioning code in the demo app with the exception of having different class names and file names. The web.config listed below is from the real app with the appsettings and connectionstrings removed.

At this point, I am completely stumped.

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。

I was having the same problem in .NET 4. I got it working with by setting the ClientIDMode="AutoID" on the control.

如果您已经迁移了 web 项目，则 user423430 的解决方案是正确的：当您自动将 VS 2003 Web 项目迁移到 VS 2005 时，Web.config 会自动修改。其中添加 。
建议不要将其与ajax一起使用：

http://weblogs.asp.net/scottgu/archive/2006/12/10/gotcha-don-t-use-xhtmlconformance-mode-legacy-with -asp-net-ajax.aspx

（ASP.NET 1.0 和 1.1 没有从其许多服务器控件发出符合 XHTML 的标记。ASP.NET 2.0 对此进行了更改，并且默认情况下从所有控件发出符合 XHTML 的标记。 ）

the solution of user423430 is the right one if you have migrated your webproject: When you automatically migrate a VS 2003 Web Project to VS 2005 the Web.config is automatically modified. <xhtmlConformance mode="Legacy" /> is added in it.
It is recommanded to not use it with ajax :

http://weblogs.asp.net/scottgu/archive/2006/12/10/gotcha-don-t-use-xhtmlconformance-mode-legacy-with-asp-net-ajax.aspx

(ASP.NET 1.0 and 1.1 didn't emit XHTML compliant markup from many of its server controls. ASP.NET 2.0 changed this and by default emits XHTML compliant markup from all controls.)

您是否可能超出了上传限制？您上传的文件有多大？

您可以在 web.config 中设置大小：

<system.web>
   <httpRuntime executionTimeout="110" maxRequestLength="20000" />
</system.web>

Is it possible you're exceeding the upload limit? What is the size of the file you're uploading?

You can set the size in your web.config:

<system.web>
   <httpRuntime executionTimeout="110" maxRequestLength="20000" />
</system.web>

当您在 Gridiview 中使用“AsyncFileUpload”时，请使用 ClientIDMode="AutoID"

When you use "AsyncFileUpload" within a Gridiview, use ClientIDMode="AutoID"
