推荐答案

这是不可用OOB，因为这很可能会导致性能问题。不过，你可以创建这样的功能自己：

That is not available OOB because it is likely to cause performance issues. Nevertheless, you can create such functionality yourself:

1. 实现自定义的 FileSystemContentProvider ，覆盖在 ResolveDirectoryAsTree（）和 ResolveDirectory（）方法的方式，在此帮助说明文章：的http://www.telerik.com/help/aspnet-ajax/fileexplorer-custom-filebrowsercontentprovider.html

1. Implement a custom FileSystemContentProvider, overriding the ResolveDirectoryAsTree() and ResolveDirectory() methods in the way, described in this help article: http://www.telerik.com/help/aspnet-ajax/fileexplorer-custom-filebrowsercontentprovider.html

呼叫递归在 ResolveDirectoryAsTree（）和 ResolveDirectory（）从内容提供商，以便采取所有列出的引用的方法文件和文件夹（例如base.ResolveDirectoryAsTree（））。一旦你收集所有需要的数据在一个地方，你可以通过它的项目的搜索。尽管这种实现的准确性，请注意此信息收集将是一个缓慢的过程，你可能达到的性能问题。

Call recursively the ResolveDirectoryAsTree() and ResolveDirectory() methods from your content provider in order to take references to all listed files and folders (e.g. base.ResolveDirectoryAsTree()). Once you gather all the needed data to one place you can make a search through the items in it. Despite of the accuracy of such an implementation, note that this information-gathering would be a slow process, and you might meet performance issues.

您可以找到有关以下帮助文章中的自定义命令的详细信息：的http://www.telerik.com/help/aspnet-ajax/fileexplorer-add-custom-button-context-menu-item.html

有可能会通过其他方式来完成这件事，但我不知道他们。

There may be other ways to get this done, but I do not know them.
