日期格式设定 \Ku=a{Ne
DataFormatString="{0:yyyy-MM-dd}" bHcb+TR3

我觉得应该在itembound事件中 xkR--/f
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) "-xm+7

9.获取错误信息并到指定页面 SeAokz>
uEQH6~\{Nl
不要使用Response.Redirect,而应该使用Server.Transfer Tz .!
$Tu%dE(OF
e.g wVk2Fr(
// in global.asax ,Iq+ v
protected void Application_Error(Object sender, EventArgs e) { :$d3}TjsA+
if (Server.GetLastError() is HttpUnhandledException) R`ajll1
Server.Transfer("MyErrorPage.aspx"); =O~1L m;
NL&(/72V
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) uyP)5,
} /6}4<~~4TA
?RGL0`Lg
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 y [e$
