　　原文网址：http://blogs.msdn.com/b/jdixon/archive/2006/01/05/ 509700.aspx
　　A few ASP.NET 2.0 TreeView coders were asking for a how to have context menus - per node - on the TreeView control. Well I spent a small amount of time on this and wanted to post one solution. A few caveats:
　　a. IE Specific
　　b. I never optimized the javascript to use parameters
　　Hope this helps soeone achieve what they need. If you find a better solution please feel free to let me know!
