高手帮忙看一下 这样的功能asp.net如何实现?
在asp.net里如何实现像winform 中datagrid控件的功能，
可编辑，可批量提交的控件。
给点思路就行 --------------------编程问答-------------------- gridview 控件 --------------------编程问答-------------------- 挺好实现的啊自己动手别什么都好 --------------------编程问答-------------------- ·双线主机 100M/35元/年,免费送数据库(自选MY/MSSQL)
·详情请访问：http://www.515dns.com --------------------编程问答-------------------- 这个问题太泛了.也太基础了,还是先动手试一下或者看看书吧 --------------------编程问答-------------------- gridview --------------------编程问答-------------------- gridview可以实现，楼主找下相关代码吧。 --------------------编程问答-------------------- repeater --------------------编程问答-------------------- 可能几位都错误的理解我的意思了，
我的要求不是用来显示数据，而是用来录入数据并提交数据。这有个网站大家可以去看看他的功能。

--------------------编程问答-------------------- 我只用过listview,但是不会有datagrid那么牛B

--------------------编程问答-------------------- 这样的效果 我也做过了
但 ajax 不使用UpdatePanel控件。
不知"liaoyukun111" 有没有到管家婆的进销存演示版去看一下。
不知它的ajax 是使用的什么
补充：.NET技术 , ASP.NET
