8.关于日期格式 Y[l*>}:w
y3^<rff3Gc
日期格式设定 :C*7DS
DataFormatString="{0:yyyy-MM-dd}" b*w@kLLN
uIOnP
我觉得应该在itembound事件中 v803@9@
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) + niz(]

9.获取错误信息并到指定页面 %~eIx=s
=P}ob eY
不要使用Response.Redirect,而应该使用Server.Transfer 7>#?-, B
$#VE C0
e.g y:t@X~
// in global.asax dux.Z9X?
protected void Application_Error(Object sender, EventArgs e) { TR;" &'#k
if (Server.GetLastError() is HttpUnhandledException) 5G$N
Server.Transfer("MyErrorPage.aspx"); <$6r1y*G
-MEp0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 6#[
} .
V5Pr}"y
?VUU[h8"v5
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 HSXv_
