Ah@e9`_r
日期格式设定 VB4V[jraCF
DataFormatString="{0:yyyy-MM-dd}" h`O$L_Z
XY9%aT*
我觉得应该在itembound事件中 $0P16ZlPC
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) D$H&^,?N

9.获取错误信息并到指定页面 >Je$WE3
)G, S7A
不要使用Response.Redirect,而应该使用Server.Transfer kCz2uG)l
;=^J_2ls
e.g 83_mR*tGNp
// in global.asax \8\TTkVSq
protected void Application_Error(Object sender, EventArgs e) { 3*j1v:x`
if (Server.GetLastError() is HttpUnhandledException) CH!\uK22
Server.Transfer("MyErrorPage.aspx"); nm%qm
m1]/8{EC7
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) o%z^@Cq
} NRP)'E
lFcHE c
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 dxZn| Y
