dfO84Z}
5
日期格式设定 iw<+rh*C
DataFormatString="{0:yyyy-MM-dd}" J$@3,=L6V
iwrS>Sm
我觉得应该在itembound事件中 L/#^&*'B
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) A03,X;S+
n`;=^^ B
9.获取错误信息并到指定页面 "m(HQ5e)*
=[3I#s?V
不要使用Response.Redirect,而应该使用Server.Transfer kznmA`#jn
Tj@s \@hv
e.g B!yAam#^
// in global.asax NkA|T1w7
protected void Application_Error(Object sender, EventArgs e) { n*hHqZl
if (Server.GetLastError() is HttpUnhandledException) k oZqoP
Server.Transfer("MyErrorPage.aspx"); Dtt[a
Qgf\gTF$r+
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `+{|k)2B
} u0Irf"Ab
^0c:ro
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 "=N[g

10.清空Cookie (khjP,
Cookie.Expires=[DateTime]; ?kISAA4x
