8.关于日期格式 rV6SN.
blHJhB&8
日期格式设定 #OE]'k
Ss
DataFormatString="{0:yyyy-MM-dd}" <
X&{6xu
}
0^wJs
我觉得应该在itembound事件中 Z<M?_<3
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) jJU9~5i?

9.获取错误信息并到指定页面 B!iz=+RNC1
d4[mR~XXT
不要使用Response.Redirect,而应该使用Server.Transfer ^Ox|q_E

+\@}IKWl-?
e.g w]Byl3}Gt
// in global.asax U)B^R
protected void Application_Error(Object sender, EventArgs e) { a-(OAzQ_
if (Server.GetLastError() is HttpUnhandledException) E>2~cC*
Server.Transfer("MyErrorPage.aspx"); hnD=DLW $
cZd{K[fuK
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) /ltGSl
} jcVK4jW

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 yL.Z{wd
