Eval 单向绑定:数据是只读的
Bind 双向绑定:数据可以更改,并返回服务器端,服务器可以处理更改后的数据,如存入数据库.
你在后台里更新了,把Bind该为Eval试试

首先,Bind方法是没有问题的。还有以后这种问题最好把你跟踪的代码贴出来。
我估计问题在  protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
= ((TextBox)e.Item.FindControl("txtName")).Text.Trim();这个是不是有问题,能直接找到这个吗?
所以,建议楼主,在这个地方考虑问题。
