8.关于日期格式 ]UOzz1
oItC;T
日期格式设定 f$ /C.E
DataFormatString="{0:yyyy-MM-dd}" V,ZRX}O
+4t
\j<T
我觉得应该在itembound事件中 U-?r>K2
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) eI2041z

9.获取错误信息并到指定页面 "j%Gr:a
Y+S<?8pA
不要使用Response.Redirect,而应该使用Server.Transfer |x.[*'X@
J{Ij
e.g XPYf1H
// in global.asax lN.&46
e
protected void Application_Error(Object sender, EventArgs e) { W*H %\Y:N
if (Server.GetLastError() is HttpUnhandledException) j.Y!E<e4]
Server.Transfer("MyErrorPage.aspx"); =[4C[s
z@[n?t!7k
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) lS;S:-
-F
} Gyu =}
L_Z`UhD3{
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 3Mh_&%!O
