8.关于日期格式 \>T1&JT
DvN_}h^nX
日期格式设定 &2@"zD
DataFormatString="{0:yyyy-MM-dd}" zt((TD2
"=s dn
我觉得应该在itembound事件中 d+Mogku2
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) *{JD=ua

9.获取错误信息并到指定页面 7d{xXJ-
Yy!G?>hC
不要使用Response.Redirect,而应该使用Server.Transfer n n[idw
0o6r3xc;
e.g .K940& Ui
// in global.asax qoan<z7
protected void Application_Error(Object sender, EventArgs e) { `U?S 9m
if (Server.GetLastError() is HttpUnhandledException) mGz'%?zj
Server.Transfer("MyErrorPage.aspx"); sS)tSt{C
zv1,DnkqF
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) $IKN7
} {3Gj
rE
*~`oA~-Q
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 qvsfU*wo?
