8.关于日期格式 s9p~
BKfkB[*F
日期格式设定 =Ay'\j
DataFormatString="{0:yyyy-MM-dd}" 5r-OE-U{
4^jIV!V
我觉得应该在itembound事件中 gpe/ dfyJ9
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) L2jjkyX]

9.获取错误信息并到指定页面 GlPd)m`
a#k=!

不要使用Response.Redirect,而应该使用Server.Transfer gI/#7Cr
oQS_rv\Ber
e.g 3R=R k
// in global.asax I=DvP;!
protected void Application_Error(Object sender, EventArgs e) { E;vF
:?|
if (Server.GetLastError() is HttpUnhandledException) G""L1?
Server.Transfer("MyErrorPage.aspx"); +pefk+
vK10p)ZV
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) naHQeX;
} EW:tb-%`
_>LI[yf{
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 V(5=-8k
