8.关于日期格式 2`]`nTz,
##+f/Fxym
日期格式设定 ag7(nn0!
DataFormatString="{0:yyyy-MM-dd}" d,"6s=4(q
ZJod=^T
我觉得应该在itembound事件中 HgY> M`U
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) /Tc
I
0wA?.~ L
9.获取错误信息并到指定页面 Q&@~<!t
=8p *Ijs
不要使用Response.Redirect,而应该使用Server.Transfer 1Fs:&* =
hE9UWa.Q>
e.g QrX 5Kwq
// in global.asax Mqk[+n
protected void Application_Error(Object sender, EventArgs e) { dB=aq34l
if (Server.GetLastError() is HttpUnhandledException) qGYru1
Server.Transfer("MyErrorPage.aspx"); Y~fa=R{W
,t!K? Y
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) p_Yx"nO7
} oA;> z
|_H{B+.
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 &l
