8.关于日期格式 m
|Isi
q<Tx'Y a
日期格式设定 :#_Ne?\a@
DataFormatString="{0:yyyy-MM-dd}" gX29c
^/'zU,
我觉得应该在itembound事件中 3C[#_&_l
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) /x2-$a:<

9.获取错误信息并到指定页面 xxnvz
.wH`9aq;5@
不要使用Response.Redirect,而应该使用Server.Transfer >:C0ZQUW
I
68Y4s
e.g 38<Z=#S
// in global.asax 'dXGd.V7u
protected void Application_Error(Object sender, EventArgs e) { io&FW!J.
if (Server.GetLastError() is HttpUnhandledException) #BLx +mLq
Server.Transfer("MyErrorPage.aspx"); *'i9
l&
A8P
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) .z+S@s[O
} ;!~&-I0l
3Q0g4#eP
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 a,ff8Qm
