8.关于日期格式 #YV;Gp(2h
CK%W+";
日期格式设定 TlJF{ <E
DataFormatString="{0:yyyy-MM-dd}" nfU}ECun4
O\z%6:'M
我觉得应该在itembound事件中 l,3tU|V
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) uW|y8 BP $

9.获取错误信息并到指定页面 #-O4x`W>
k3w#^
"i
不要使用Response.Redirect,而应该使用Server.Transfer 1F-L(\oKm
a7R7Ks|q
e.g [&&4lKC}u
// in global.asax auU{Iy
protected void Application_Error(Object sender, EventArgs e) { /fEXAk
if (Server.GetLastError() is HttpUnhandledException) j(hC't-
Server.Transfer("MyErrorPage.aspx"); [VHt#JuN,
#k6T_ki
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) SqLKF<tY]/
} }#@LZ)]hK
]cK@nq)
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 4D5)<3N=d'
