8.关于日期格式 Z1fY' f
()aCE^C
日期格式设定 U`6|K$@
DataFormatString="{0:yyyy-MM-dd}" e=&~6bs1U
~xqiasE#K
我觉得应该在itembound事件中 ~v8X>XDL?T
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) xL15uWk-

9.获取错误信息并到指定页面 Z
)c\B
|^1g*fy?
不要使用Response.Redirect,而应该使用Server.Transfer qm_l#
u6
gXI-{R7Me
e.g d[6 'w ?
// in global.asax D9+qT<ojN
protected void Application_Error(Object sender, EventArgs e) { Tx}Nr^
if (Server.GetLastError() is HttpUnhandledException) JMB#KzvN[
Server.Transfer("MyErrorPage.aspx"); XZ%[;[
1'f_C<.0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) |:C0_`M9
} T`e`nQ0nn
9n(68|^$
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 |3~m8v2-
