e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; +H K)A%QI
this.style.color=’buttontext’;this.style.cursor=’default’;"); ;|hEXd?b

8.关于日期格式 JL9d&7-
NS
l$5E
日期格式设定
,qRSB>5c
DataFormatString="{0:yyyy-MM-dd}" sQA{[l!aj
_e.b#{=9
我觉得应该在itembound事件中 fxDY:l
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) )Q\ZYCPOr
P#H#@:/3
9.获取错误信息并到指定页面 '^l/e: (H3
gkpNT)
不要使用Response.Redirect,而应该使用Server.Transfer >5Zpx8W
DJE/u qE
e.g 0<L@f=i
// in global.asax SPV'0* Z
protected void Application_Error(Object sender, EventArgs e) { \2<2&=h?
if (Server.GetLastError() is HttpUnhandledException) '3o0J\cz
Server.Transfer("MyErrorPage.aspx"); F.=uJdl.!
)).;p_nLZ
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) D^PsV
} 9ok|]d P
8m A6l0
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 bq4H4?j

10.清空Cookie E|9LUPcb
