日期格式设定 eX/$[SL[
DataFormatString="{0:yyyy-MM-dd}" 3m'6 cMQ

我觉得应该在itembound事件中 J/ ~]A1fP6
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) w6tY6bf}

9.获取错误信息并到指定页面 BN67o]*]<
V^D#i(5
不要使用Response.Redirect,而应该使用Server.Transfer %]` W sG
PC5FfX
e.g /WMLr5
// in global.asax ,b8AB_yw
protected void Application_Error(Object sender, EventArgs e) { \$I
)}
if (Server.GetLastError() is HttpUnhandledException) iJK9-k~
Server.Transfer("MyErrorPage.aspx"); Ra5cfkH;
WF]:?WE%
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) \`^jl
} +y2*[
@QofsWC
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 Q]HRg4r
