8.关于日期格式 x$Ko|:-
$]<C C `
日期格式设定 Mc#uWmc 7
DataFormatString="{0:yyyy-MM-dd}" WZ"NG|
FVW<F(g`
我觉得应该在itembound事件中 [=z1~dXKb
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 9OuK}Ssf
KJo[!|.
9.获取错误信息并到指定页面 AU)"L_
i}
R] tHd=kf
不要使用Response.Redirect,而应该使用Server.Transfer 5)+(McJC
AyB-+oTf(
e.g /pan{.< k
// in global.asax 8p,q9Ey
protected void Application_Error(Object sender, EventArgs e) { BNw^ _j1
if (Server.GetLastError() is HttpUnhandledException) 16 _HO%v->
Server.Transfer("MyErrorPage.aspx"); v`A^6)U#M
7L|w~l7R~
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) S7N3L."
} Qw!cd-zc
({zt=}r,
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 8xJdK'
