8.关于日期格式 4T-9F
-fl?G%:(!0
日期格式设定 vrtK~5K
DataFormatString="{0:yyyy-MM-dd}" k)W8%=R
~RQ6DG^
我觉得应该在itembound事件中 c2}?[\U]
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) gI&& LwT4
kIAWI;H{
9.获取错误信息并到指定页面 AsRS7V
`laaT5G\y
不要使用Response.Redirect,而应该使用Server.Transfer P@Wi^svj
la ~T)U7
e.g yZ[H&>
// in global.asax "_qH+=_R
protected void Application_Error(Object sender, EventArgs e) { a!,q\p8<t0
if (Server.GetLastError() is HttpUnhandledException) {:&t;5qz^
Server.Transfer("MyErrorPage.aspx"); sXzxEhp
oYNP,8r^
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) IqK??KSC
} L\||#w
zcGeXX}V?
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 *rO#UE2

10.清空Cookie ]X,C9
