如果直接用DateList 绑定到数据库的话就能把textbox的取出来，但是如果用代码绑定的话就不能取出来这是为什么呢谢谢！！！！！ --------------------编程问答-------------------- 还是不太明白：直接用DateList 绑定和代码绑定？？？ --------------------编程问答-------------------- 谢谢搞定了忘了加ispostback了 --------------------编程问答-------------------- 谢谢搞定了忘了加ispostback了 --------------------编程问答-------------------- ....... 自己解决了最好 --------------------编程问答-------------------- 晕.. --------------------编程问答-------------------- page_load
加ispostback

补充：.NET技术 ,  ASP.NET
