8.关于日期格式 O&}R
>FJK$>[1:p
日期格式设定 ggpa!R
DataFormatString="{0:yyyy-MM-dd}" B*P;*re

我觉得应该在itembound事件中 GaV OMT
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ?}S!8;d

9.获取错误信息并到指定页面 /<dl"PWkJv
]mjKF\
不要使用Response.Redirect,而应该使用Server.Transfer BqdGU-Q
[?(qhp!
e.g O2fFh_\
// in global.asax =vDpm,
protected void Application_Error(Object sender, EventArgs e) { F!2VTPm9z
if (Server.GetLastError() is HttpUnhandledException) `6LVXDR
Server.Transfer("MyErrorPage.aspx"); +ZV?yR2yn
A0Q1"b=
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 8%xiHPVg
} NxB/U_j
+vPCr&40
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 v+dT7*^@
