8.关于日期格式 YRC`2)_'
0;k3
日期格式设定 rWbL_1Eq
DataFormatString="{0:yyyy-MM-dd}" }$$b6G

我觉得应该在itembound事件中 [FC%_R&&
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) aQRZyE}

9.获取错误信息并到指定页面 (AwbZ n*
>fb*X'Zi%
不要使用Response.Redirect,而应该使用Server.Transfer vW]BOzK
@|d|orMC
e.g j&44wuf
// in global.asax E"w7/k#3}C
protected void Application_Error(Object sender, EventArgs e) { /CX<k gz@
if (Server.GetLastError() is HttpUnhandledException) DORFK
Server.Transfer("MyErrorPage.aspx"); lJU[9)Q_
7L]fCw
p[
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) wz:w R+
} WcqYpPv
,u\M7,a^
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 ~L}0)FZ\9
