@]{:juD~
日期格式设定 tbi(e49S
DataFormatString="{0:yyyy-MM-dd}" _ID =]NJ_
-(.\> F
我觉得应该在itembound事件中 y\[GS2nTX
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) a% 82I::t
&sPu3.p
9.获取错误信息并到指定页面 Hkj|

O`(it%Ho!
不要使用Response.Redirect,而应该使用Server.Transfer f]^ @z<FC
{S5D~A*a+
e.g Tb]' b
// in global.asax O /4)aW3B
protected void Application_Error(Object sender, EventArgs e) { [k6,!e[/uG
if (Server.GetLastError() is HttpUnhandledException) x6*.zo5e
Server.Transfer("MyErrorPage.aspx"); qv+}|+aL:
!yTjO
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) #9hSo
} 3qH`zYgh
qS2]|7q?Tc
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 xZ&S7G1
