8.关于日期格式 23zB@aE_?1
k<m{Wp;-
日期格式设定 @`)A)
DataFormatString="{0:yyyy-MM-dd}" gE|_hfm(

我觉得应该在itembound事件中 oGa8}Vtc
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) O",:0<

9.获取错误信息并到指定页面 WJ8i,7
VGkwrS;+I
不要使用Response.Redirect,而应该使用Server.Transfer i&RPYbT{
K^EW*6vB8O
e.g =}F &jl
// in global.asax sT| 8a
protected void Application_Error(Object sender, EventArgs e) { K%.\@l2Cp
if (Server.GetLastError() is HttpUnhandledException) ]JbGP{UiN
Server.Transfer("MyErrorPage.aspx"); Dr&2qX!
c5pF?kFaD
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) +g%kr~w=
} Pr9$(6MX
=
oQ-I
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 Y`w+?}(M
