8.关于日期格式 sA6Hk B.
?e-rwaW
日期格式设定 SsX$l<t*
DataFormatString="{0:yyyy-MM-dd}" _,^f,WO~
F-@yH
我觉得应该在itembound事件中 GYw/KT~$
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) u|23M,
8!v|`Ky
9.获取错误信息并到指定页面 `x=kb;
DQhHU1
不要使用Response.Redirect,而应该使用Server.Transfer ,;6%s>Cvd(
I&|8
qx#
e.g fp||<B
// in global.asax RPa]VL1W
protected void Application_Error(Object sender, EventArgs e) { M}jl\{
if (Server.GetLastError() is HttpUnhandledException) TJP;!uX
Server.Transfer("MyErrorPage.aspx"); 7h9oY<W
T2-x 1Sw_
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 6iQqOAG
} Yaq0mef0
_x5-!gK
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 2^s@n3t
