8.关于日期格式 EzeDShN=J
9cx!N,R t
日期格式设定 GwU>o:g"
DataFormatString="{0:yyyy-MM-dd}" {R6Zwjs
HnYFE@Nl:U
我觉得应该在itembound事件中 .P0Qs&i
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) #E~WVTOw
v;NZ"1=_
9.获取错误信息并到指定页面 6#lC(ko'
_g/TH-;^
不要使用Response.Redirect,而应该使用Server.Transfer cVv4gQD\
(tz_D7c$F
e.g
}tS6Z:fOY
// in global.asax WPh |~]by<
protected void Application_Error(Object sender, EventArgs e) { m}'t'l4 c
if (Server.GetLastError() is HttpUnhandledException) UHsrZgIRYT
Server.Transfer("MyErrorPage.aspx"); o )}<
3T.M?UG>
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) el*pYI
} AD4L`0D
6@Z'fT4
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 s5Bmv\e.i5
