8.关于日期格式 Cr a@
\d&/,?,Ey
日期格式设定 "7.
lsL5
DataFormatString="{0:yyyy-MM-dd}" z5k9|.hgw
iem@K
我觉得应该在itembound事件中 0]._|Ubn6)
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) fEMz%CwH
?cH,!2
9.获取错误信息并到指定页面 t'.oty=
z/Kjz$l!
不要使用Response.Redirect,而应该使用Server.Transfer *Bj7\8cKC
nB+UxU@
e.g G8Qo]E9-/
// in global.asax v
Wt{kg;
protected void Application_Error(Object sender, EventArgs e) { @}r2xY1
if (Server.GetLastError() is HttpUnhandledException) 8e:\T.)M
Server.Transfer("MyErrorPage.aspx"); Wi5rXZS
M#U #I:z%
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) .vm.g=-q
} (0cL!
N;;
9cO
m$
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 ~ ZN]2}

10.清空Cookie ?;c&5'7ct
Cookie.Expires=[DateTime]; <8SRt-Cr
Response.Cookies("UserName").Expires = 0 KVC$o+<'`%
