8.关于日期格式 *c\XQy
boI&q>-6Re
日期格式设定 DaQ+XUH?
DataFormatString="{0:yyyy-MM-dd}" Y&1N*@YP
3G[|4v?[<_
我觉得应该在itembound事件中 "=w:LRw
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) XzPOqZ`Nv
F$-f j "jC
9.获取错误信息并到指定页面 #M||t|9iu?
J'ZC5Xr
不要使用Response.Redirect,而应该使用Server.Transfer #UE}JR3g
>$tU @mq
e.g HC=ZcK'W
// in global.asax !?>QN'p.b
protected void Application_Error(Object sender, EventArgs e) { vV xw*\`<6
if (Server.GetLastError() is HttpUnhandledException) 74ho=
Server.Transfer("MyErrorPage.aspx"); U)xebU.!S
}hsNsQ
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) nU' qE
} DS;\24>H
K&n-(m%
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 ttdY]+Fj
