So roundtrip required again. Have you ever seen tree of content at MSDN or navigation menu at our site? Probably, you have noticed that nodes of the tree are downloaded to the browser dynamically. You need not to reload whole page to show some new nodes when you expand it.

记录比较多，建议你分层加载
page_load里面加载第一层节点
然后用事件驱动加载后面的几层
我就是这么做的，也只有iewc提供了这方面的服务器端事件
不然几千条记录，一次加载时间太长
不知道你有没有实际做过，我想要的是让它在加载后面的节点的时候不刷新(autopostback要设置成false)，起码做到本页面不刷新，如何做？
