8.关于日期格式 ilde<!?
ImG8v[Q
E
日期格式设定 hsQDRx%H}
DataFormatString="{0:yyyy-MM-dd}" ht*(@MCr<
\i/HHP[%
我觉得应该在itembound事件中 ~&<t++ g
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) =
IA<>+NS
9.获取错误信息并到指定页面 vQ*RrHG?c
`kJ)E;v;3
不要使用Response.Redirect,而应该使用Server.Transfer Pjk2tf0j`
]E-3/r$_cO
e.g 1I`F?MT
// in global.asax $cK}Tlq
protected void Application_Error(Object sender, EventArgs e) { A
yr,
if (Server.GetLastError() is HttpUnhandledException) p3Qls*
Server.Transfer("MyErrorPage.aspx"); z bYv}q
Yb^e7Eug
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `kuu}YUi
} aPzn4}~/_
YHO}z}f[!
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 Zj!,3{jX^
