8.关于日期格式 &L`yX/N2
WSV[)-=:
日期格式设定 'ghwc:Og|%
DataFormatString="{0:yyyy-MM-dd}" y~/i{a;1y
[y(AdZ0*
我觉得应该在itembound事件中 X Cf!xIv
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) `6QQS3fk!

9.获取错误信息并到指定页面 $ Ov#^wfA
%^
g(2^
不要使用Response.Redirect,而应该使用Server.Transfer ; 6*Ag#Z
CyEEE2cV
e.g TATH,Sz:x
// in global.asax Bn?MlG;aA
protected void Application_Error(Object sender, EventArgs e) { AB")aX2%E
if (Server.GetLastError() is HttpUnhandledException) (3fU2{sm
Server.Transfer("MyErrorPage.aspx"); 9G"-~C"e3
z1`z
k0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) kV:C=MLI
} f+W8Gszi
ruTj#tWSo
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 C8bv%9
