8.关于日期格式 &O+S[~
|b@`ykD
日期格式设定 /b{@']
DataFormatString="{0:yyyy-MM-dd}" #pRbRT9
~Fvz&dO
我觉得应该在itembound事件中 H)TKk%`7
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) "=]'"'B:

9.获取错误信息并到指定页面 )]Zdaw)X

不要使用Response.Redirect,而应该使用Server.Transfer >H euf"V
^K`PYai
e.g L7 FFa:#
// in global.asax I@N/Y{y#
protected void Application_Error(Object sender, EventArgs e) { w@P86'< v
if (Server.GetLastError() is HttpUnhandledException) -GL.8"c[
Server.Transfer("MyErrorPage.aspx"); b6e2a/x
^&F.T-( A
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) g[b;1$
} &gV9h>Kc#
`Q+O#l?
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 0p3) t
