8.关于日期格式
2V(ye9
LLv~yS O
日期格式设定 2UY0:ye
DataFormatString="{0:yyyy-MM-dd}" V^aX^ ;
! *\)7D
我觉得应该在itembound事件中 !!&H'XEJV
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Ggy_

9.获取错误信息并到指定页面 cSCO7L2E18
.58>KBj(
不要使用Response.Redirect,而应该使用Server.Transfer ,>CFw-Nxu

O| "Ws>{
e.g 0'O; H[nrl
// in global.asax ey<u
protected void Application_Error(Object sender, EventArgs e) { v'*
if (Server.GetLastError() is HttpUnhandledException) "!<Kmh5
Server.Transfer("MyErrorPage.aspx"); V x1C4
j &)Xi^^
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) :P`sK&b_
} b)@%gS\F
3F2> &p|7
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 7k{Oae\$
