}I]j&\
日期格式设定 kE/`n],1U
DataFormatString="{0:yyyy-MM-dd}" 7J9l.cM3

我觉得应该在itembound事件中 .'|mY$U~]
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) |3}5:k

9.获取错误信息并到指定页面 Hjs}
AR%hf
不要使用Response.Redirect,而应该使用Server.Transfer "8 N"Udu
CjZZm^O
e.g R?cUy8?'S
// in global.asax w*50ZS;N
protected void Application_Error(Object sender, EventArgs e) { |G(1[RNu
if (Server.GetLastError() is HttpUnhandledException) ?c!:81+\
Server.Transfer("MyErrorPage.aspx"); Dv&>*0B
qM%O
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) F4Zn5&.)
} i+f7
b~7Jh:%@;
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 1Cm~X$S.
