Question

你在绑定页面信息的，在page_load 里面 加上

我也 在PAGE_LOAD 中加了代码 .可以调试的时候得到的值 还是以前的

Answer 2

貌似你的方法里没先把放数据容器给null一下吧？ 每次读的时候确保null的容器，再读出来不就是最后更新的了么？

Answer 4

string IDCard = Request.Form["txt_cid"];
string bank_user = Request.Form["txt_bankuser"];// txt_bankuser.Text;
string bank_Area = txt_bankdiqu.Text;
string bank_name = txt_bankname.Text;
string bank_card = txt_bankCarID.Text;在这个区域里得到的值是以前的
