8.关于日期格式 5F#FC89Kk
yT[=!M
日期格式设定 a*uG^~
).
DataFormatString="{0:yyyy-MM-dd}" 1\nzfxx
O`T_'.Lk
我觉得应该在itembound事件中 ^fmuBe}d{
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) $i1:--~2\
Z+=-)&L
9.获取错误信息并到指定页面 $:&b5=i
N1"p ;czK
不要使用Response.Redirect,而应该使用Server.Transfer M>xT\
@^GI :z
e.g s\p 1EL(
// in global.asax _%#Uh#7P$
protected void Application_Error(Object sender, EventArgs e) { NMUF)ksjN
if (Server.GetLastError() is HttpUnhandledException) [3x},KM
Server.Transfer("MyErrorPage.aspx"); i*@ZIw
%,e,KcP'
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) _7~q|
} Ctx>#uN6
8,(--A
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 X"7x_yOZ
