8.关于日期格式 jDkc~Wwa
vzgudxG'z
日期格式设定 pQ6t]DJ4
DataFormatString="{0:yyyy-MM-dd}" U7Sl@-#|
%.r5E2'
我觉得应该在itembound事件中 itvy[b-*
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) kk>0XPk
".7KEnx
9.获取错误信息并到指定页面 DNTRLIKa
34&$_0zn
不要使用Response.Redirect,而应该使用Server.Transfer {pi67"mYp
B3i=pcef
e.g q'U-{~q%
// in global.asax H#d! `
protected void Application_Error(Object sender, EventArgs e) { E].a|4sh
if (Server.GetLastError() is HttpUnhandledException) IcNI uv
Server.Transfer("MyErrorPage.aspx"); l.LFlwt
!&:.Uh
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) A 'P}mrY
} R,k[Kh
~S<F
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 [&k& $04_
