8.关于日期格式 QHOem=B
C;_10Rb2ut
日期格式设定 -rUn4a
DataFormatString="{0:yyyy-MM-dd}" 7tJPjp4l
!9B)/Xi
我觉得应该在itembound事件中 bX8Bn0#a+
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) b2hB'!m

9.获取错误信息并到指定页面 U)2\=%8
$5l 8V
不要使用Response.Redirect,而应该使用Server.Transfer 1qtu,yIf
in$Pk$ c
e.g X2~>Z^,
U
// in global.asax *:wu{3g}M`
protected void Application_Error(Object sender, EventArgs e) { 0Db#W6*^
if (Server.GetLastError() is HttpUnhandledException) *G^QS"%
Server.Transfer("MyErrorPage.aspx"); s/8>(-H#
d x?4)lb
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) \)pk/
} 1s .Ose
!h4L_D0
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 mJl|dk_c

10.清空Cookie 5P [b/.n
Cookie.Expires=[DateTime]; O.Z<dy+
Response.Cookies("UserName").Expires = 0 .>_p7=a
