8.关于日期格式 ? EHheZ{
SYf1dbc..u
日期格式设定 ?*
,
DataFormatString="{0:yyyy-MM-dd}" f9<"
\RPwSx
我觉得应该在itembound事件中 gs/o cu
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) z$d<ep{6

9.获取错误信息并到指定页面 -&]!ig5v
l\Ww^
不要使用Response.Redirect,而应该使用Server.Transfer D:IG;Rsc
M=&,+#z<V
e.g /J!:_Nq
// in global.asax @x743}Y\
protected void Application_Error(Object sender, EventArgs e) { nN-S5?X#
if (Server.GetLastError() is HttpUnhandledException) xs Pt
Server.Transfer("MyErrorPage.aspx"); )[M:#;,L
":s_O.
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) WcM\4q@
} >KdV]!H
);q~TZ[Do
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 .oLV\'HAR
