;P%1j| 7
日期格式设定 [;),\\u,d
DataFormatString="{0:yyyy-MM-dd}" ~<F8ug#
.MoU1n{Yc
我觉得应该在itembound事件中 RO/FF<f
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) GH:jH]u!V

9.获取错误信息并到指定页面 '^~{@~ ;%L
65$+{s
不要使用Response.Redirect,而应该使用Server.Transfer *VhL\IjN]
MJ
[m
e.g LR.<&m%~.
// in global.asax 41?HY{&2
protected void Application_Error(Object sender, EventArgs e) { A1>OY^p3%
if (Server.GetLastError() is HttpUnhandledException) O so#+
Server.Transfer("MyErrorPage.aspx"); *@=/qkaJaI
9c,'k#k
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) pm0{R[:T7
} UJ7*j%XQz_
EC!02S
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 T{ XS")Vw
