8.关于日期格式 ixp %aRRP
;J4_8N-
日期格式设定 `f(!i mN
DataFormatString="{0:yyyy-MM-dd}" *]rV,\z:
o,d:{tt
我觉得应该在itembound事件中 90q*V%cS
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) [wExjLW

9.获取错误信息并到指定页面 )_BteLo-
?VJ Fp^Ra
不要使用Response.Redirect,而应该使用Server.Transfer )TLDNpH?J
uJ%ql5XDV
e.g =Ij;I~
// in global.asax Uc/%4Gx
protected void Application_Error(Object sender, EventArgs e) { v;OA hF r|
if (Server.GetLastError() is HttpUnhandledException) I;No++N0
Server.Transfer("MyErrorPage.aspx"); 3[c54S+(U
^Tl|v'
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) zpY8w#b
} qRr;&M &t_
M|\XFO
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 qU}[(9~Ru
