8.关于日期格式 p.8
[kN_b<Pc,
日期格式设定 8'zl\:@N
DataFormatString="{0:yyyy-MM-dd}" nXhP ME
NkNFx<9T
我觉得应该在itembound事件中 z\UXnRL
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) p6BDhT(RS
xFThs,w
9.获取错误信息并到指定页面 i ?M-~EKu
tKe-Dk9
不要使用Response.Redirect,而应该使用Server.Transfer 9)S3{i6w
zb4@U=?w}
e.g <+q`Dk
// in global.asax B[7,Hy,R
protected void Application_Error(Object sender, EventArgs e) { yF6AI@y
if (Server.GetLastError() is HttpUnhandledException) '/\*l<
Server.Transfer("MyErrorPage.aspx"); '&,p>aM
AhA&=l
i;
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) *My9r.F5o
} d
oEuKT
_{#K
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 M6Xzyt|

10.清空Cookie `kvIw,c.
Cookie.Expires=[DateTime]; {Y2J: x
Response.Cookies("UserName").Expires = 0 YRBJ(v"9
