&QKK
[H=l#W@
日期格式设定 <Q@{6
DataFormatString="{0:yyyy-MM-dd}" ?8ady%
.ls
rI'kZ0&
我觉得应该在itembound事件中 ,veo/k<"r8
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 1[]V @P^

9.获取错误信息并到指定页面 c|F2 6$rv
F#Bi*YY
不要使用Response.Redirect,而应该使用Server.Transfer +a|u,'u
7,3 g{8
e.g A",Xn/d
// in global.asax JpZ3T~Wrf
protected void Application_Error(Object sender, EventArgs e) { 0IxHB|^$
if (Server.GetLastError() is HttpUnhandledException) l'RuzBQr
Server.Transfer("MyErrorPage.aspx"); g>n1mK|
:1gcLsF
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ge[&og/$
} 97n,^t2F\
<ahcE1h
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 ZW ZKy JQ
