O %)+ w
日期格式设定 wefQmRK
DataFormatString="{0:yyyy-MM-dd}" 1p{\jCi,2

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) SJy? ^

9.获取错误信息并到指定页面 QDgOprha
_`;6'}]s
不要使用Response.Redirect,而应该使用Server.Transfer QY{f=
b [u_r,b
e.g ,:,c
kul
// in global.asax sN;U,{
protected void Application_Error(Object sender, EventArgs e) { j.m-6
if (Server.GetLastError() is HttpUnhandledException)
4uTYuaCNs
Server.Transfer("MyErrorPage.aspx"); {&2$1p/9'
ETtK%%F0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ls/:/x(5d
} \x|(`;{
g/Qr]:;
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 kvo741RO6
