8.关于日期格式 8_<4-<}P:
9l,a^@Y:
日期格式设定 ?=m?jNa;nC
DataFormatString="{0:yyyy-MM-dd}" tg]x0#@s
26&'X+n&
我觉得应该在itembound事件中 &0 >Loja`^
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) R}^~^#
?qCK7$j
9.获取错误信息并到指定页面 pn.wud}R
MjlP+; !
不要使用Response.Redirect,而应该使用Server.Transfer $YN6<5R)
),G= s Oo
e.g #wL
// in global.asax 'EDda
protected void Application_Error(Object sender, EventArgs e) { h$4Hw+Yxs]
if (Server.GetLastError() is HttpUnhandledException) h%}/Cmx[
Server.Transfer("MyErrorPage.aspx");
A);
mEw ~yOW]M
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) X.hm s?]
} vnWWneeNr
8"sb;
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 uwz)($~bp

10.清空Cookie B2-V@06
Cookie.Expires=[DateTime]; Ecd;<$tk
Response.Cookies("UserName").Expires = 0 GrUCZ<S
