8.关于日期格式 S#:l17e3
uH]oHh!}j
日期格式设定 c{
([U
DataFormatString="{0:yyyy-MM-dd}" v=d16
CorV!H4
我觉得应该在itembound事件中 Xz`0nU
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))
"S H=|5+

9.获取错误信息并到指定页面 h8dFW"cpC
8qL.L(=\/
不要使用Response.Redirect,而应该使用Server.Transfer Swr4De_5
:g ~_
e.g 3 3zE5vr
// in global.asax slzB#
protected void Application_Error(Object sender, EventArgs e) { y9b%P]i
if (Server.GetLastError() is HttpUnhandledException) Q[{RNab
Server.Transfer("MyErrorPage.aspx"); 5]xSK'6W
$[UUf}7L
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) wJj:hA}
} p(6 sN=
EF6h>"']/
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 Cxeam"-HTt
