8.关于日期格式 y>}dKbCN
S !Dq8
日期格式设定 3D<s#
DataFormatString="{0:yyyy-MM-dd}" dd4g?):
3Z.<=D
我觉得应该在itembound事件中 oJ}!qrrH
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Qu4Bd|`(k
et[n ;nl>V
9.获取错误信息并到指定页面 os/_ObPiX
O3,IR1
不要使用Response.Redirect,而应该使用Server.Transfer yu8xTh$:
k@QU<cvI
e.g V2-fJ!
// in global.asax Hrb67a%b
protected void Application_Error(Object sender, EventArgs e) { LRNgpjE}
if (Server.GetLastError() is HttpUnhandledException) 7P!<c/ E
Server.Transfer("MyErrorPage.aspx"); {OHaI ;
M1(+_W`
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) {s^vAD<~x3
} s~OGlPK
('yBIb\ue
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 MVe:[=VOT|
