8.关于日期格式 RVa{%
EdS7m,d
日期格式设定 Hr;\}
DataFormatString="{0:yyyy-MM-dd}" ~{np G
0J1&6b
我觉得应该在itembound事件中 Hc-Ke1+
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) &^])iG,Ew

9.获取错误信息并到指定页面 &uG@I=}TIY
cmbl"Pqy1
不要使用Response.Redirect,而应该使用Server.Transfer F!ra$5u
Mt(;7q@1c
e.g 87:V-*8
// in global.asax 3>buZ6vh
protected void Application_Error(Object sender, EventArgs e) { 4>te>[
if (Server.GetLastError() is HttpUnhandledException) NpF)|Ppb{
Server.Transfer("MyErrorPage.aspx"); P<IZ%eS3B
Hp-vBoEk
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) hrTl:\
} to;cF6X
$3{I'r]
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 ,IQ%7*f;O_
