8.关于日期格式 XNWtX-[^@
e^>>"tr
日期格式设定 ['=O>YY
DataFormatString="{0:yyyy-MM-dd}" "Zgwe,#
EGUlLqP6e
我觉得应该在itembound事件中 7,+eG">0
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) x?{UWh%

9.获取错误信息并到指定页面 IDH~nMz

+0@,I
不要使用Response.Redirect,而应该使用Server.Transfer ES&u*X:

e.g 1"ZtE\{
"
// in global.asax +9b{Y^^~T
protected void Application_Error(Object sender, EventArgs e) { KHML!f=mu
if (Server.GetLastError() is HttpUnhandledException) I.jqC2G
Server.Transfer("MyErrorPage.aspx"); S@HC$
uI7n{4W*x
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) w~b:9_reY
} $:F+Nf

OX]$Xdb2:
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 >0{}tRm-P&
