8.关于日期格式 gt \O
!+o`,K TYp
日期格式设定 96#aGh>
DataFormatString="{0:yyyy-MM-dd}" -\I".8"YE
2~B9 (|
我觉得应该在itembound事件中 @9AK!I8f
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ]1)#Y
v!WkPvU
9.获取错误信息并到指定页面 =6O<1<[y
opIbs7k-
不要使用Response.Redirect,而应该使用Server.Transfer .~AQxsGH
QLLMSa+! \
e.g T*1 `MIkv
// in global.asax (k$KUP
protected void Application_Error(Object sender, EventArgs e) { o,yZ1"
if (Server.GetLastError() is HttpUnhandledException)
=yCz!vc
Server.Transfer("MyErrorPage.aspx"); ]!'}{[1}
Nc_Qd4<[@G
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) v/G)E_
} BenUyv1d
"lnI@t{o
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 ]w/%>
