3;t {V$
日期格式设定 W81dLeTZg
DataFormatString="{0:yyyy-MM-dd}" X

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Fr{}~fRW<

9.获取错误信息并到指定页面 J 6%CF2
2]i>kV/,0
不要使用Response.Redirect,而应该使用Server.Transfer 5 52U~t
%X^K5Io
e.g 7JL*y\'
// in global.asax iFBH;O_~
protected void Application_Error(Object sender, EventArgs e) { W, YYL(L
if (Server.GetLastError() is HttpUnhandledException) b>_eD-
Server.Transfer("MyErrorPage.aspx"); N{<9Njmm
9~Ve}NB#z&
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) M tD{/.D>
} x4 .Y&Wq#
8F(Vd99I
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 6:$+"@ps
