2m\m/O
日期格式设定 gfm;xT/y
DataFormatString="{0:yyyy-MM-dd}" [fxuUmU

我觉得应该在itembound事件中 5DOE3T`^Oc
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) oIR.|=Hk{
<BPRV> 0X
9.获取错误信息并到指定页面 {`F1u?l
ZBJ3 VK
不要使用Response.Redirect,而应该使用Server.Transfer um[!|g/
H_Os4}
e.g &bLC(e]
// in global.asax 74_xR
protected void Application_Error(Object sender, EventArgs e) { } L <,eV
if (Server.GetLastError() is HttpUnhandledException) +#s;yc#=2
Server.Transfer("MyErrorPage.aspx"); f ;wc{qy
4uUs7T
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) <s}|ZnGE
} U CRAw3=
_q)!B,y-/N
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 13a(FG
