/'|'3J]HP
日期格式设定 m35Blg34
DataFormatString="{0:yyyy-MM-dd}" A`4Di8'Me
Q(lj&!?1k
我觉得应该在itembound事件中 |_l\.
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) UA4Q9<>~

9.获取错误信息并到指定页面 U\S%Jq*
?p{xt$<p
不要使用Response.Redirect,而应该使用Server.Transfer \jn[kQ+pJ
<j1l&H|ux,
e.g a,Gd\.D
// in global.asax 5,:tjn
protected void Application_Error(Object sender, EventArgs e) { s:Us*i=H,
if (Server.GetLastError() is HttpUnhandledException) yjvH)t/!.
Server.Transfer("MyErrorPage.aspx"); )c@I|L
$[VeZ-
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) cvn4Q- ^
} xG<H${
k;
:" ZH
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 u>;#.N/
