button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") ~F; ~

8.关于日期格式 CK=TD`$w
UKpc3Jo:~
日期格式设定 _c $F?9:
DataFormatString="{0:yyyy-MM-dd}" 'c/S$_r
"xduh3/~=
我觉得应该在itembound事件中 fMm.V=/+
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) =pk5'hBAi

9.获取错误信息并到指定页面 W/@-i|v
T0e- X
不要使用Response.Redirect,而应该使用Server.Transfer f`vu+nw
sS{!z@\Lf
e.g M 8NWQ^Y
// in global.asax E'
_6v
protected void Application_Error(Object sender, EventArgs e) { `i5 \(cdl
if (Server.GetLastError() is HttpUnhandledException) =nff;Xu
Server.Transfer("MyErrorPage.aspx"); ss0`9:z
E (.~[-K4
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) KD* xFap
} UFzC8
`UD,ne
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 M*
