d}',Bl+u{$
日期格式设定 D] 2+<;>`>
DataFormatString="{0:yyyy-MM-dd}" 0nz

我觉得应该在itembound事件中 3P p*ID
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) E4[\lX$J
9=I(AYG{m
9.获取错误信息并到指定页面 $/45*
!{SU G+.2
不要使用Response.Redirect,而应该使用Server.Transfer 0r=Lilu{q
s/Wg^(&M
e.g r/L3j0
// in global.asax !U/:!e`N
protected void Application_Error(Object sender, EventArgs e) { (.!q~G
if (Server.GetLastError() is HttpUnhandledException) N1(}3O
Server.Transfer("MyErrorPage.aspx"); );;UNO21+
Z-H Kdv!d
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) |_~BV&g,N
} 'eqvK|Uj:
jt2m-*aP
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 mcDW&jwQ
