这些天研究AJAX, 没事翻看msdn的文章, 偶然发现一篇<<ASP.NET 中的自定义脚本回调>>的文章, 顿时眼睛一亮, 心像这不实现我想要得AJAX局部页面更新功能了么! 但这篇文章字太多, 看着费劲, 我就试着找一些代码例子, 结果找到了一些代码, 但都是beta 版http://www.dotnetjunkies.com/Tutorial/E80EC96F-1C32-4855-85AE-9E30EECF13D7.dcik, 在正式版中编译不过, 后来参考msdn, 终于让他通过, 简单易行.

如果不想去别的网站 截取内容, 再加点javascript不就实现了传说中的ajax功能了么? 还去研究那么赋值ajax libraries干嘛呢, 不过rico的drag-drop功能,还是很眩的, 可以用一下. 省下的就是等MS的ajax出来再研究就行了.可恨live writer 不支持插入code. 每次贴code都很费劲
