8.关于日期格式 VE{3} S
F9E<K]7K
日期格式设定 Bb^;q#S1
DataFormatString="{0:yyyy-MM-dd}" +|'c>,?2H
Hmd]
FC,_
我觉得应该在itembound事件中 b#toM';T
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) X#TQ_T"
lG!|{z7+0
9.获取错误信息并到指定页面 p&bROuw<T
S^>,~R.TX
不要使用Response.Redirect,而应该使用Server.Transfer MLje4
>qjq=Ege
e.g b8"?VS5-"
// in global.asax LO khjHR
protected void Application_Error(Object sender, EventArgs e) { dx&'fe*?
if (Server.GetLastError() is HttpUnhandledException) `YLD`(\
Server.Transfer("MyErrorPage.aspx"); D=m9fFz
[nc4{0 aT'
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) >eqxV|]i
} t2I5hSf
v99B7VH4
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 uRRQyZ

10.清空Cookie r1.nTO%
