8.关于日期格式 *nsnX/e(-
ktw!T{
日期格式设定 !aW*dD61
DataFormatString="{0:yyyy-MM-dd}" B yy-Cc
JIY ^N9_
我觉得应该在itembound事件中 P2
K>|r
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 5cNzG4z
M;p q2$
9.获取错误信息并到指定页面 vq0M[Vy
}%>$}4 ,
不要使用Response.Redirect,而应该使用Server.Transfer e}Af"LI
>h!.Gj
e.g <E}]t,'3
// in global.asax >e$^#\D
protected void Application_Error(Object sender, EventArgs e) { 9Pob|UA
if (Server.GetLastError() is HttpUnhandledException) F&L?J_=
Server.Transfer("MyErrorPage.aspx"); /<?X-IDz.{
<R~~yW:H
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) dT,m{[+
} 6B;_uIq5
K_lL\
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 VrGb;L'[
b1,T!xL
10.清空Cookie PcSoG\-G<
Cookie.Expires=[DateTime]; v/TlXxfil
Response.Cookies("UserName").Expires = 0 fkv{\zN
