我可以使用ASP.NET Ajax库在异步回发期间从服务器到客户端检索数据吗？

Question

ASP.NET Ajax Library provides some client-side events. For instance:

Sys.Application.add_load(
    function(args) {
        // handle the end of any asynchronous post-back. Every-time there's
        // a server round-trip, this method will be called.
    }
);

During the asynchronous post-back I want to retrieve information to the client. This information must be available in some event like the discribed above.

Does the UpdatePanel or the ScriptManager have any server-side way to retrieve data back to client during an asynchronous post-back?

Answer 1

尝试ScriptManager.RegisterDataItem 。
