8.关于日期格式 5EhE`k4
BMjfqX
日期格式设定 i:k-"
DataFormatString="{0:yyyy-MM-dd}" >(tO
QeN
o>u!CL<
我觉得应该在itembound事件中 IA4+ad'\E
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 9v?V

9.获取错误信息并到指定页面 %|?1B$s0
!GN Xt4D
不要使用Response.Redirect,而应该使用Server.Transfer 1o#vhk/"+
zz3 r<?#5
e.g [:pl-_.C
// in global.asax DcU C,
protected void Application_Error(Object sender, EventArgs e) { Q&wYc{TUbm
if (Server.GetLastError() is HttpUnhandledException)
^@q#$/z
Server.Transfer("MyErrorPage.aspx"); h6FgS9H
:0dfB&7
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) !fZLQc
} {y/-:=S)A
\\iK'|5YG
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 $h]NXC6J
