8.关于日期格式 AU-n&uX
"qc6=:y}
日期格式设定 .9md~j:o^s
DataFormatString="{0:yyyy-MM-dd}" yQ#:J9HMJ
kJWN.
我觉得应该在itembound事件中 #Z6'?p9
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) L?5Ck<!xG
hx/N1x
9.获取错误信息并到指定页面 "4vy lHIo
Dfq(Iv
不要使用Response.Redirect,而应该使用Server.Transfer Hwo$tVa:=
Y"OG@1V;8
e.g GA7}K:LP'k
// in global.asax 1x,[6H
protected void Application_Error(Object sender, EventArgs e) { aK`@6F,]j
if (Server.GetLastError() is HttpUnhandledException) atXS-bg*
Server.Transfer("MyErrorPage.aspx"); Qs9gTBS;
hstbz
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ~T) Q$
} u,}{I}x_
U|g:`v7
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 4C}bJzZ
