8.关于日期格式 ~4"adOv
4&r[`gL
日期格式设定 ?w#V<3=
DataFormatString="{0:yyyy-MM-dd}" =kp#v

我觉得应该在itembound事件中 |F=!0Id<
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Ynl^Z

9.获取错误信息并到指定页面 E2 Q[
"9'~6b
不要使用Response.Redirect,而应该使用Server.Transfer LBq~?Q.e
",!#7h
e.g $sTbFY
// in global.asax qsOA(+ZP
protected void Application_Error(Object sender, EventArgs e) { |`+kZ-M*
if (Server.GetLastError() is HttpUnhandledException) X;lL$
Server.Transfer("MyErrorPage.aspx"); ,m;S-Im_Xr
IFcxyp
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ,pM~Phmp
} "(zvI>A
|5oK04<
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 c7UmR?m
