8.关于日期格式 T <RWz
Iapzh y2l
日期格式设定 >_X(rar0
DataFormatString="{0:yyyy-MM-dd}" wHQYBYKcd
7K!n'dAi6
我觉得应该在itembound事件中 HBw0N?
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) }~#qDrK
s3~6[T?8
9.获取错误信息并到指定页面 V_9\Ax'X
@VsK7Eo
不要使用Response.Redirect,而应该使用Server.Transfer fi6_yFl
z7a@'+'
e.g XLm@, A[
// in global.asax " j:15m5
protected void Application_Error(Object sender, EventArgs e) { _$v$v$74^
if (Server.GetLastError() is HttpUnhandledException) ^AO2%09.S
Server.Transfer("MyErrorPage.aspx"); xCMuq9zt@
C+gu'hD
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 1i Q(q\%
} 5zt5]zl'
l_2YPon
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 h5))D!

10.清空Cookie y|WOw(#
