@;4zrzQi7
日期格式设定 EWt[z.`T1
DataFormatString="{0:yyyy-MM-dd}" 2s8a

sdrfsrNvB-
我觉得应该在itembound事件中 {?0lBfB"
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) FUzzB94a

9.获取错误信息并到指定页面 iyE7V_O T
}#+^{P3 ;
不要使用Response.Redirect,而应该使用Server.Transfer gg/-k;@ Rf
0> E r=,e
e.g :4w ?#
// in global.asax lFj]4
protected void Application_Error(Object sender, EventArgs e) { 7z,C}-q
if (Server.GetLastError() is HttpUnhandledException) *a^(vo
Server.Transfer("MyErrorPage.aspx"); 1H`,WQ1mG
MJ)RvNF
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) n&/
`
} 1.hyCTnI
#%2rP'He
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 {TROoX~H?

10.清空Cookie I
