SharePoint。更改文档库中的文档图标？

我想在运行时更改文档库中的文档图标。图标应根据我在代码中的某些条件进行更改。文件的扩展名是什么（txt，doc，pdf等）没有区别。目前我使用HTTP模块解析服务器响应并在运行时更改图标。但是，此解决方案不可靠，因为页面HTML标记可能会更改，不同的视图具有不同的行为，并且在SharePoint 2010中存在注册HTTP模块的问题。是否有任何API或任何其他可靠的方式在运行时更改文档图标？SharePoint。更改文档库中的文档图标？
我将不胜感激任何帮助。由于事前， -Petro

你可以得到你想要修改图标库的DocIcon场（通过代码）并修改其模式。正如你可以看到的那样，在章节中有很多XSLT，但它很简单，可以添加新的模式而没有大的问题（旧的模式可以被删除）。另一种方法是创建自己的自定义字段类型，并使用它来代替标准字段来显示图标。
