8.关于日期格式 {qJ1ko)$
#a,PZDaE
日期格式设定 bJ {'<J
DataFormatString="{0:yyyy-MM-dd}" 9-a0 :bP
'$(^W@M#6
我觉得应该在itembound事件中 E]n&=\
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) H3=qe I
s)D;a-F
9.获取错误信息并到指定页面 !``,gExH
u^I|T.w<r6
不要使用Response.Redirect,而应该使用Server.Transfer j-}O0~Jz
}!.(n=idZ
e.g YZ8>OwQz2
// in global.asax [<yaXQxl
protected void Application_Error(Object sender, EventArgs e) { P{>!5|k
if (Server.GetLastError() is HttpUnhandledException) >jLY"
Server.Transfer("MyErrorPage.aspx"); Flm%T-Dl
~4Fvy'
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) }V`"s^
} R.1.)P[
,<P
vovg_
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 4p;`C
