8.关于日期格式 NX:i]t
2M+'9+k~
日期格式设定 ~m.@{Do0p
DataFormatString="{0:yyyy-MM-dd}" <lwkjt=RV

我觉得应该在itembound事件中 ~uz 4
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 2:l8RH!Y

9.获取错误信息并到指定页面 )]5}d$83
}W k!):=y
不要使用Response.Redirect,而应该使用Server.Transfer QWV12t$v
-?68%[4lm_
e.g -.X-02
// in global.asax QGQ>shIeZ
protected void Application_Error(Object sender, EventArgs e) { IXef}%1N?
if (Server.GetLastError() is HttpUnhandledException) {z/Y~rf
Server.Transfer("MyErrorPage.aspx"); 'rQ>Z A_8
]J7.d$7T
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) V}kQXz"9
} =%V(n{7=
BSB;0O M
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 G\ht)7SGgf
