8.关于日期格式 ob+euCuJ
f>'Y(dJ'W
日期格式设定 T5urZq*R
DataFormatString="{0:yyyy-MM-dd}" +% /s*EC'w
) 9,
我觉得应该在itembound事件中 ys_`e
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) B1]bRxwn?
zYXV;
9.获取错误信息并到指定页面 (R`B'OtGg
r&-m=Kk$
不要使用Response.Redirect,而应该使用Server.Transfer 9a'-Y
,mRyQS'F
e.g Bq/:Nd[y
// in global.asax (F7(^.MG
protected void Application_Error(Object sender, EventArgs e) { j4=(H:c~E
if (Server.GetLastError() is HttpUnhandledException) zf3v5Hk
Server.Transfer("MyErrorPage.aspx"); yH][(o=2
9nu3+.&P
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) J0zn-
} rt
JtK6t
H>r!i4l
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 3_JCU05H}
