日期格式设定 )6%a9&~H

我觉得应该在itembound事件中 ]MC5 uKn
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 89{`GKWX

9.获取错误信息并到指定页面 e-nwR
$RYOj{1
不要使用Response.Redirect,而应该使用Server.Transfer @k\,XV`T~t
wRZS+^hx
e.g _YN
C}PUU
// in global.asax g9Ty%|Q7(
protected void Application_Error(Object sender, EventArgs e) { c<sq0('`
if (Server.GetLastError() is HttpUnhandledException) xEv?2n@A
Server.Transfer("MyErrorPage.aspx"); `NNP}O2
=}0$|@pl
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
e'p"gX
} X`fm5y
tBETNt7
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 Ap 3B'
