8.关于日期格式 ks(PH6:]<
{nj\dU
日期格式设定 A4( ^I
u
DataFormatString="{0:yyyy-MM-dd}" =YLt?5|e

我觉得应该在itembound事件中 Z!LzyCVl
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) V :d/;~

9.获取错误信息并到指定页面 P d*}0a~
Z [68ji]
不要使用Response.Redirect,而应该使用Server.Transfer W=F?+KgL
"* 'rzd
e.g H~x0-q<8
// in global.asax s2w.V
O
protected void Application_Error(Object sender, EventArgs e) { 6@Eip[e
if (Server.GetLastError() is HttpUnhandledException) /SN.M6~
Server.Transfer("MyErrorPage.aspx"); 8MW|CM4Q
3@6f%Dyj
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ;9u6]%hQTX
} ;]<$p[m
9H.E15B
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 5%tIAbGW
