8.关于日期格式 N|N3x7=gs
MP Z3D9
日期格式设定 v
^[39*8
DataFormatString="{0:yyyy-MM-dd}" F{06 _T
{]_uMg#!
我觉得应该在itembound事件中 [^CV>RuO
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) [.se|]t7X
Od+6 -J
9.获取错误信息并到指定页面 [x=jH>Y
Kl7WQg,XOi
不要使用Response.Redirect,而应该使用Server.Transfer PyVC}dUAX
%^sTU4D5
e.g 9.'h^#C
// in global.asax [(Xy.L7x
protected void Application_Error(Object sender, EventArgs e) { 'c2W}$q
if (Server.GetLastError() is HttpUnhandledException) De7Ts
Server.Transfer("MyErrorPage.aspx"); =4V&*go*\
*B`Zq)
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) gE#>RM5D
} j',W 64
k@zy
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 v+p{|X-

10.清空Cookie {3;AwhN0H
