8.关于日期格式 8w:ay,=
wH|%3@eJ
日期格式设定 J2Dn
DataFormatString="{0:yyyy-MM-dd}" li%@HdA!
pb97S^K[
我觉得应该在itembound事件中 *y4g\#o.
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) .eN"s'
Y!M0JSaM
9.获取错误信息并到指定页面 9?\cm}^?
p7YYAh@x\
不要使用Response.Redirect,而应该使用Server.Transfer |mH* I
KiXfR\S~C
e.g j55_wx@cA
// in global.asax 11l=zv
protected void Application_Error(Object sender, EventArgs e) { HAH\#WE
if (Server.GetLastError() is HttpUnhandledException) bhUE!h<
Server.Transfer("MyErrorPage.aspx"); ;!HQ!#B
sK%b16#
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ;>7~@
K
} 5J`w8[;

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 nT|WJ%
