button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") h{Zd, 9H

geJO#;
日期格式设定 > a"4aYj
DataFormatString="{0:yyyy-MM-dd}" b+!I_g4P

我觉得应该在itembound事件中 gVU&Yl~/^
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) rG"QK!R5

9.获取错误信息并到指定页面 ,.-85isco
jB -wJNP/
不要使用Response.Redirect,而应该使用Server.Transfer }$D{YHF
P d)<Iw^<
e.g ;UoXj+Z
// in global.asax F?.J1]
protected void Application_Error(Object sender, EventArgs e) { g6l&;S40
if (Server.GetLastError() is HttpUnhandledException) OaCp3No
Server.Transfer("MyErrorPage.aspx"); jdW#;
]7+y
yr,Oq~e
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ^/_1y[j
} .In8!hjYy4
<h[l)-86
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 u(b Pdf@kz
r>.^4Z@
10.清空Cookie Y&y5^nG
Cookie.Expires=[DateTime]; 6fcn(&Qk
Response.Cookies("UserName").Expires = 0 4M3{P
