8.关于日期格式 Hw8`/'M=%5

>bf7+D
日期格式设定 Two$wL/
DataFormatString="{0:yyyy-MM-dd}" IH?.s

我觉得应该在itembound事件中 /C29^ P
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) s
}q6@I

9.获取错误信息并到指定页面 SlvQ)jw%
v/6QE;BY&Q
不要使用Response.Redirect,而应该使用Server.Transfer RWf4Wh?d
:%qJ AjR&
e.g +hg|!SS@5
// in global.asax :|xV}
protected void Application_Error(Object sender, EventArgs e) { S5]rIcM
if (Server.GetLastError() is HttpUnhandledException) A][\L[8X
Server.Transfer("MyErrorPage.aspx"); :M(%sv</
h0`@yo
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) :WejY`}H%
} ='<0z?Af
RP&H9>
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 'l2'%@E>
