8.关于日期格式 Yt/SnF
| ,1bkJt
日期格式设定 da00p-U
DataFormatString="{0:yyyy-MM-dd}" }dd k}wga
sk7rU+<
我觉得应该在itembound事件中 W<rTq0~$?
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) $@_<$t
FM9X}%5nu9
9.获取错误信息并到指定页面 ;Y@!:p-H
%l8*t$8
不要使用Response.Redirect,而应该使用Server.Transfer 4#@W;'
ib(>vp$V
e.g SvX=isu!.
// in global.asax C?[a3rNH(
protected void Application_Error(Object sender, EventArgs e) { B|Fl,55
if (Server.GetLastError() is HttpUnhandledException) .B 85!lCF
Server.Transfer("MyErrorPage.aspx"); uEScAeQXsI
'nlRY5@2
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 7>'uj7r]=
} e' U"`)S
" xDx/d8B
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 UK"}}nO@e
