8.关于日期格式 6`-<N !
Wx}-H/t'2
日期格式设定 -e$ T}3IV
DataFormatString="{0:yyyy-MM-dd}" Qz=e'H
xw{K,;WeO
我觉得应该在itembound事件中 4Kt0}W
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) =zH)R0!eG
(<B%Gy@
9.获取错误信息并到指定页面 )z&C&Gqz
$@s-OQ}
不要使用Response.Redirect,而应该使用Server.Transfer WCY._H>|
8'E7Uj
e.g sI6*.nR
// in global.asax Y*b$^C%2
protected void Application_Error(Object sender, EventArgs e) { X\BFvSv8C
if (Server.GetLastError() is HttpUnhandledException) nKd'5f1
Server.Transfer("MyErrorPage.aspx"); .Ao
_cx
?6"U('y>n
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) R{[v#sF >#
} "KF]s.
+PBl3
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 p+ReQ.5|
