8.关于日期格式 1]lm0bfs
?MhY;z`=
日期格式设定 B{0m0-l
DataFormatString="{0:yyyy-MM-dd}" xo46L\
ua-cX3E
我觉得应该在itembound事件中 D; 0iNcit
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Y=#g_(4*

9.获取错误信息并到指定页面 oU.LYz_
f/:XIG
不要使用Response.Redirect,而应该使用Server.Transfer LOkNDmj
4Fr\=TX
e.g h6dVT9
// in global.asax liUrw7,
protected void Application_Error(Object sender, EventArgs e) { p7A&r:qq#
if (Server.GetLastError() is HttpUnhandledException) B0^0d*8t|@
Server.Transfer("MyErrorPage.aspx"); n0T'"i[
ci@U
a}T
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) jI8qiZ);~
} 7O)U(<70
cIO7RD$8
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 &.Jp,Xt)

10.清空Cookie hoc$aqP6pp
Cookie.Expires=[DateTime]; IR+dGqIjZb
Response.Cookies("UserName").Expires = 0 FX FTf2*T
