日期格式设定 ]Yf8

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) &p=(0$0&-

9.获取错误信息并到指定页面 +^a@U^V
MU1T="N^+
不要使用Response.Redirect,而应该使用Server.Transfer ShOB"J-
QtOT'<2t]
e.g RG-,<G`
// in global.asax ST\d-x
protected void Application_Error(Object sender, EventArgs e) { T"E%;'(cp)
if (Server.GetLastError() is HttpUnhandledException) 3.%jet1
Server.Transfer("MyErrorPage.aspx"); PH!rWR
wT:mfS09N
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ]kH8T'
} (-{.T
6Q`7>l.|?
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 9A}nZ1Y
