8.关于日期格式 .-[UHO05^8
*:3flJt
日期格式设定 `Bnp/9q5
DataFormatString="{0:yyyy-MM-dd}" GLt#]I"LY
j"/i+r{"E
我觉得应该在itembound事件中 )=;0
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) on+
c*#

9.获取错误信息并到指定页面 4W~pAruwr
9rtcI[&?0
不要使用Response.Redirect,而应该使用Server.Transfer $ W(m
&?/h#oF@\
e.g #Z}\;a{vZ
// in global.asax ju(&v*KA
protected void Application_Error(Object sender, EventArgs e) { s*:J=+D]G
if (Server.GetLastError() is HttpUnhandledException) VLN=9
Server.Transfer("MyErrorPage.aspx"); 3IZ^!J
7Rk eV
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) $TL~SVHj;{
} DTt/nmKAqJ
#~q{6()e:
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 g%#"
