8.关于日期格式 [#%@,C
<j1r6.E)
日期格式设定 >z73uKA(
DataFormatString="{0:yyyy-MM-dd}" (9b%'@A@m
zm3$)*p1
我觉得应该在itembound事件中 KE-0/m4yJ
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) P 1

9.获取错误信息并到指定页面 <fHN^O0TS
)Myx(w"S
不要使用Response.Redirect,而应该使用Server.Transfer _w2%!+'
iNilk!d6Q3
e.g S0ltj8t
// in global.asax Z29LtKr
protected void Application_Error(Object sender, EventArgs e) { GI>(S
if (Server.GetLastError() is HttpUnhandledException) R ^ZOcONd-
Server.Transfer("MyErrorPage.aspx"); +
Y!:@d
#kE8EhQZ
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) pG22Nx
} 5!aI~(3<
5n1`$T.WG
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 n2|@Hz_

10.清空Cookie z#lIu
Cookie.Expires=[DateTime]; % bKy
