$T^O3 8$
日期格式设定 8|d lt$

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) tJUMLn?

9.获取错误信息并到指定页面 TA`*]*O(
GTYGm
不要使用Response.Redirect,而应该使用Server.Transfer D(~6h,=m
|LcN_,}6
e.g cwz
% LKh
// in global.asax \kzxt/Ow
protected void Application_Error(Object sender, EventArgs e) { G( nT.\
if (Server.GetLastError() is HttpUnhandledException) LdU, 32
Server.Transfer("MyErrorPage.aspx"); wQ2'%T|t
_Eq:Qbw#
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) /!eC;qp;[
} X3!btxa%t
bRLmJt98P
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 lR{eO~'~V
