D]fgBW-
日期格式设定 .nEMd/pX
DataFormatString="{0:yyyy-MM-dd}" Ar~<l2,{r
d]K8*a%[-

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Ha]vG@?+

9.获取错误信息并到指定页面 Pbbi*&i
}LS.bQKqi,
不要使用Response.Redirect,而应该使用Server.Transfer ?`Mk$Y%my
|Wck-+}U
e.g
,_V/W'
// in global.asax z@ZI$.w
protected void Application_Error(Object sender, EventArgs e) { J"h2"$v,
if (Server.GetLastError() is HttpUnhandledException) 7gOu|t
Server.Transfer("MyErrorPage.aspx"); pk'd&.
uj\&-9gEi
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 4VvE(f
} 2h<_?GM\s
hFtjw6
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 <#"_Qgdix

10.清空Cookie 6b2h\+AP

Response.Cookies("UserName").Expires = 0 OXZK|C;M}
