8.关于日期格式 i
`8Y/$aT
"Zicac@N
日期格式设定 I."4u~[
DataFormatString="{0:yyyy-MM-dd}" u`X}AKC
U#_rcu
我觉得应该在itembound事件中 t#J
#DyY5
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) +%RXV~
`!T6#6h
9.获取错误信息并到指定页面 785Y*.p
)6zwprH!
不要使用Response.Redirect,而应该使用Server.Transfer HaamLu
65A>p:OO
e.g QO~TuC
// in global.asax z//6yr
protected void Application_Error(Object sender, EventArgs e) { P(r}<SM
if (Server.GetLastError() is HttpUnhandledException) 3?(||h{
Server.Transfer("MyErrorPage.aspx"); `S7${0e
?+#E&F
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) iNs
} hAZ"M:f
7"
cgj#
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 8eoDE. }
