8.关于日期格式 LJWTSf"f?
B7!;]'&d
日期格式设定 Ihg~Q4t
DataFormatString="{0:yyyy-MM-dd}" VHW`NP 5Jl
,E?4f
@|X
我觉得应该在itembound事件中 "Hht
g:
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 9 ZGV%Tw
jn$j^51`C
9.获取错误信息并到指定页面 lUHtjr
vL$|9|W(
不要使用Response.Redirect,而应该使用Server.Transfer
4{Udz!
9 #Y2`pT
e.g ;g9% &
// in global.asax E?Cj/o
protected void Application_Error(Object sender, EventArgs e) { n+?-
if (Server.GetLastError() is HttpUnhandledException) :_Fxy5}
Server.Transfer("MyErrorPage.aspx"); #W|!fILL
IBET'!j4"
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ufPCx|x~
} >)^NJ2Fd
<Y>3
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 o8{<qn|
