8.关于日期格式 ]@ g$<&
BFRSYwPr
日期格式设定 lt"*y.%@b
DataFormatString="{0:yyyy-MM-dd}" TniKH(w/

我觉得应该在itembound事件中 s&hP^tKT
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 55en

9.获取错误信息并到指定页面 -L3RzX
kV<)>Gs
不要使用Response.Redirect,而应该使用Server.Transfer %P6!vx:&^b
|}Lgo"cTC
e.g ':dHYvP/UX
// in global.asax eF\C?4
protected void Application_Error(Object sender, EventArgs e) { S?tLIi/
if (Server.GetLastError() is HttpUnhandledException) !d)i6W?
Server.Transfer("MyErrorPage.aspx"); ^%^0x'"
gWPa8q<b
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) oa7Hx<Y
} |g!#
\
e8v=n@0
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 aC`
