ME7jF9d
日期格式设定 ~^cx a%
DataFormatString="{0:yyyy-MM-dd}" ,
\|S BS
d!5C$C/x
我觉得应该在itembound事件中 U8KB@E
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) vyP3]+n

9.获取错误信息并到指定页面
AC@WhL
AA"?2dF
不要使用Response.Redirect,而应该使用Server.Transfer obKWnet
LF vKF .
e.g "5"6mw?
// in global.asax @r]wZ~@
protected void Application_Error(Object sender, EventArgs e) { A9'
[x7N
if (Server.GetLastError() is HttpUnhandledException) @,F8gv*
Server.Transfer("MyErrorPage.aspx"); l)<
'1dqe
R5c
Ya
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) "Lk-R5iFd
} @.;] $N&J
#;sUAR?]
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 D0Yl?LU3

10.清空Cookie mD{<Lp=
Cookie.Expires=[DateTime]; m=<Tylv
Response.Cookies("UserName").Expires = 0 u[q1]]
