8.关于日期格式 [TFp2B~)#
8lS
RK%
日期格式设定 wzJdS}Yy!y
DataFormatString="{0:yyyy-MM-dd}" <*-8E(a
m/(/!MVy
我觉得应该在itembound事件中 7Cbr'!E\_V
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) :i@
$s/
$b2~H+u(
9.获取错误信息并到指定页面 moh,a B#
Kv<mDA!
不要使用Response.Redirect,而应该使用Server.Transfer yLK %lP
fX6pW%Q'6
e.g m\bmBK"I
// in global.asax H{Lt,#
protected void Application_Error(Object sender, EventArgs e) { f5l\3oL
if (Server.GetLastError() is HttpUnhandledException) [p}~M-$V8Y
Server.Transfer("MyErrorPage.aspx"); e"XolM0IM
Wm5[+z|2?9
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) QnS#"hc\a
} *M0O&" ~j
`P-d. M6Oa
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 W1t_P&i
