8.关于日期格式 U:n3V
w`")^KXi
日期格式设定 AQH\ ;L
DataFormatString="{0:yyyy-MM-dd}" >w~Hq9
nA#FGfZ{Ge
我觉得应该在itembound事件中 *$eMM*4
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) *Fe
~ojH$=K>d
9.获取错误信息并到指定页面 8IX,q
7;T6hKWV[
不要使用Response.Redirect,而应该使用Server.Transfer JXKqQxZ[X
XpLK0YI
e.g r#xq 8H=_m
// in global.asax T3W?-,
protected void Application_Error(Object sender, EventArgs e) { L&WhX3$u
if (Server.GetLastError() is HttpUnhandledException) \q0wY7w
Server.Transfer("MyErrorPage.aspx"); ?'dsiA[
)ZcwG(o0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 9Rg|o CP_
} cy6lsJ"?
y@ 'm D*z
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 G2A^+R0\

10.清空Cookie mjwh40x.o
