0Y*gJ!a
日期格式设定 {mnSTL`
DataFormatString="{0:yyyy-MM-dd}" dG>Wu o

我觉得应该在itembound事件中 l=~99mE
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) B9)qv>m

9.获取错误信息并到指定页面 OXX(OCG>
7TPLVa=hO
不要使用Response.Redirect,而应该使用Server.Transfer a~>0JmM+N
4*XP;`
e.g A|_%'8
// in global.asax [I<'E
LX
protected void Application_Error(Object sender, EventArgs e) { MQH8Q$5D
if (Server.GetLastError() is HttpUnhandledException) O\F^@;]F6
Server.Transfer("MyErrorPage.aspx"); 0*IY%=i
:'rZZeb'
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) i^ cM@?
} t>GLZzO
'a/6]%QFd!
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 H&=4y) /.
