8.关于日期格式 M\D25=(
oU/{<gs
日期格式设定 1EHL8@.M
DataFormatString="{0:yyyy-MM-dd}" yt{?+|tXU
~N]pB]/][
我觉得应该在itembound事件中 7m.>2U
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) uwc@~=;

9.获取错误信息并到指定页面 ~[Z,:=z
.!)i
不要使用Response.Redirect,而应该使用Server.Transfer +lhnc{;WJv
A(D3wctdr
e.g 6=p!`DOd
// in global.asax >9Z7l63+}
protected void Application_Error(Object sender, EventArgs e) { f taa~h*
if (Server.GetLastError() is HttpUnhandledException) 7{Zs"d{s
Server.Transfer("MyErrorPage.aspx"); c+ukVn`r
*:Uq
;)*
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 4G'-"u^g
} z#GrwE,r
=h\uC).t&
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 yqKSaPRA
