8.关于日期格式 {K,In)4
U&5*>fd=
日期格式设定 4<efj
DataFormatString="{0:yyyy-MM-dd}" u!_l/'\
]{>AU^=U
我觉得应该在itembound事件中 t'qYM5
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) F!omkN

9.获取错误信息并到指定页面 h!EA;2yGKa
{0zn~+
不要使用Response.Redirect,而应该使用Server.Transfer 1\.$=N
.|UQ)J?s
e.g J!I)G&:
// in global.asax mDB
protected void Application_Error(Object sender, EventArgs e) { Cm}2 >eH
if (Server.GetLastError() is HttpUnhandledException) $NXP)Lic)
Server.Transfer("MyErrorPage.aspx"); o96C^y{~S
IrLGAQ0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) UtZ,q!sg
} sibYJK Oy

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 Fnw:alWr
