8.关于日期格式 b By'v/
U7jhV,gO4
日期格式设定 axOi5
DataFormatString="{0:yyyy-MM-dd}" 9U&~(;
0T(O'v}.
我觉得应该在itembound事件中 j,\tejl1
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) hK
Fk$A
MST:.x ;
9.获取错误信息并到指定页面 h>~jQ&\M
[+y&HNf
不要使用Response.Redirect,而应该使用Server.Transfer L^6"'#
kea e.6[
e.g SE6>vKR/.
// in global.asax /g13X,.H
protected void Application_Error(Object sender, EventArgs e) { ejP,29
if (Server.GetLastError() is HttpUnhandledException) j[_t6Z
Server.Transfer("MyErrorPage.aspx"); 9*BoYFw92*
;9}w|!/
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) uPI v/&HA
} 3gC\{y!8
qi(&8in
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 ThjUiuWe

10.清空Cookie 7We?P,A\;
Cookie.Expires=[DateTime]; Tw2Xe S
Response.Cookies("UserName").Expires = 0 JtSuD>H`"
