8.关于日期格式 C <H$}f
:!fU+2$`^(
日期格式设定 W\O.[7JP
DataFormatString="{0:yyyy-MM-dd}" *7C l1o
bK|nxL
我觉得应该在itembound事件中 uP1]EA
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) P?zL`czWd

9.获取错误信息并到指定页面 1r<'&f5
6\m'MV`R!
不要使用Response.Redirect,而应该使用Server.Transfer &zHY0fxX
fjHd"!)3
e.g )SfM `W)Y
// in global.asax vZIx>
protected void Application_Error(Object sender, EventArgs e) { o3.b='HAm
if (Server.GetLastError() is HttpUnhandledException) Obc wmL
Server.Transfer("MyErrorPage.aspx"); $~r=I[5'(
=64Ju Wvo
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ,1i l&
} ki]i[cdk
A{gniYqvB`
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 ,DCrhk

10.清空Cookie KXcE@q9
Cookie.Expires=[DateTime]; !{XVaQ?x
Response.Cookies("UserName").Expires = 0 cB2~W%H
