200分，急问。为什么我的detalist在update是始终取到HtmlInputText的原有值，无法得到改变后的值

rbjojo 2004-11-15 12:06:38

点edit后INPUT btnStatusCode中显示123456，修改为9999后，点save，在 UpdateCommand中设置断点的结果发现StatusCode 还是取到的是123456，也就是修改后的值没有提交到服务器。
为什么？
在线等待，各位老大多谢了，已经好几天没有办法了

<EditItemTemplate>
<TABLE width=550 border=0 >
<TR>
<TD ><INPUT id=btnStatusCode runat=server size=5 value="<%#Container.DataItem(0)%>" runat="server"></TD>
<TD >
<INPUT id=btnDes runat=server size=48 value="<%#Container.DataItem(1)%>" runat="server"></TD>
<TD >
<asp:LinkButton id=Linkbutton3 runat="server" ForeColor="000077" CommandName="Update">SAVE</asp:LinkButton></TD>
</TABLE>
</EditItemTemplate>

Private Sub DataList1_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles DataList1.UpdateCommand

StatusCode = DirectCast(dli.FindControl("btnStatusCode"), HtmlInputText).Value
Description = DirectCast(dli.FindControl("btnDes"), HtmlInputText).Value

End Sub

绑定DataGrid的代码要放在
If Not IsPostBack) then

end if
里面，否则每次回传首先执行Page_Load，对DataGrid重新绑定，那么它里面的值肯定就恢复原状了

主体思想：定制自己的操作日志。（多用户的业务平台）

既然提到操作日志，根据实际情况不光光记录一些普通的记录，还得记录一些，比如：用户，用户ID，操作类型，操作保存的值，客户端IP，客户端计算机名，一些自己需要的字段，操作时间等等。

其实网上很多关于日志的文章，但是基本上都是公用的，想打造自己的还是自己写的好~

不要把这个操作日志想的很神秘，其实就是收集
