8.关于日期格式 "ot#g"
2C"[0*.[N
日期格式设定 1AAOg+Y@U"
DataFormatString="{0:yyyy-MM-dd}" Sgq?r-Q.
K410.o/=-
我觉得应该在itembound事件中
6Eyinv
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) aKC,{}f$m
vk.P| Y-;
9.获取错误信息并到指定页面 NNw0
G&
8=,-r`oNy
不要使用Response.Redirect,而应该使用Server.Transfer JUdQ Q
y87oW_"h
e.g xj;V
// in global.asax _BHEK
protected void Application_Error(Object sender, EventArgs e) { 'e:(61_
if (Server.GetLastError() is HttpUnhandledException) LZ<^b6Dxk
Server.Transfer("MyErrorPage.aspx"); oUx%ra{
0Ait7`
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ^/fasl$#
} (0u(<qA\
66-G)+4
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 R(p3*t&n

10.清空Cookie Cxra(!&
Cookie.Expires=[DateTime]; "? ON0u9
Response.Cookies("UserName").Expires = 0 5%RiM|+
