+>AVxV=A#
日期格式设定 K>5bb
DataFormatString="{0:yyyy-MM-dd}" &x=_n'
F_i"v5#
我觉得应该在itembound事件中 #f;6Ia>#
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) t:P7ah

9.获取错误信息并到指定页面 E{QjmlXQ<
65VTKlDD
不要使用Response.Redirect,而应该使用Server.Transfer OoRg:"9{#
he@Y1CY
e.g <%W&xk
// in global.asax S,udpQ7
protected void Application_Error(Object sender, EventArgs e) { SUIu.4Mz
if (Server.GetLastError() is HttpUnhandledException) O_GHvLO=
Server.Transfer("MyErrorPage.aspx"); >wL!`:c'"
"=KFag
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 9YB?wh'S[
} ZsCwNZR

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 7xY&7 x(v
