ASP.NET Devexpress 控件无法在实时服务器上正确显示

Question

在 Visual Studio.NET 2010/localhost 上，使用 Devexpress 编辑器和文本框控件开发的 ASP.NET 页面看起来不错。上传到 IIS 7.5 时，生成的 html 源代码几乎相同，除了对脚本 WebResources 的引用（script src="/WebResource.axd?d=tpzArdJXo7erNNqm...），但验证器不会触发并且控件具有不同的风格。

在 DevExpress 网站的某个地方，我读到 WebResources 可能由于某种原因变得无法访问，应该停止 IIS 服务，清除临时 ASP.NET 文件和 GAC 缓存，然后重新启动。重启 IIS 是不可能的，我不相信这是唯一的解决方案。

有什么建议吗？

我使用的是 DevExpress 版本 10.1.7.0。这是 web.config：

Answer 1

请在 Web 应用程序的 IIS 设置中打开 Handler Mappings 属性并确定

AssemblyResourceLoader-Integrated 和 AssemblyResourceLoader-Integrated 4.0 的请求路径等于 WebResource.axd 和 类型是 System.Web.Handlers.AssemblyResourceLoader。

另外，请确保应用程序池的管道模式设置为集成模式。

Olaf，您的 web.config 文件不包含关于我们http handler 的注册信息。要注册 ASPxHttpHandlerModule 并启用其功能，只需在表单上放置 DevExpress Web 控件或手动将特定代码添加到 web.config 文件。有关详细信息，请参阅 How to manually register a HttpHandler Module 主题。
