8.关于日期格式 @x
]^blq
Qn&^.e9I
日期格式设定 6;V1PK>9
DataFormatString="{0:yyyy-MM-dd}" 1D DOUV
<Wq{ V;$
我觉得应该在itembound事件中 \,t<{p_Q
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ixpG[8s
/a)=B)NH
9.获取错误信息并到指定页面 fbkjK`_q
d'D\#+%>=
不要使用Response.Redirect,而应该使用Server.Transfer >:|q J$J.
S*:w\nXP~
e.g zjE4v-H:l
// in global.asax Rj=Om
protected void Application_Error(Object sender, EventArgs e) { 3&:fS|L~c
if (Server.GetLastError() is HttpUnhandledException) S`.-D+.68
Server.Transfer("MyErrorPage.aspx"); T+!kRigN~P
o)WSMV(&f
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) KK|Jach
} VHNiTp
;wB3H
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 :E*U*#h/

10.清空Cookie `^{P,N>X
Cookie.Expires=[DateTime]; rNp#5[e
Response.Cookies("UserName").Expires = 0 ??Ac=K\
