I}:/v$btM
日期格式设定 Kq*^*vWC
DataFormatString="{0:yyyy-MM-dd}" YcI]_[

我觉得应该在itembound事件中 ck}y-,>,[O
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))

9.获取错误信息并到指定页面 $qvNv[
T:-Uy&pBEN
不要使用Response.Redirect,而应该使用Server.Transfer VS`S@+p
r'8e"pTi
e.g G$Dg*<
// in global.asax ~q/`Z)(yc
protected void Application_Error(Object sender, EventArgs e) { 3lJK[V{'#'
if (Server.GetLastError() is HttpUnhandledException) B4b UcYk
Server.Transfer("MyErrorPage.aspx"); GP[$&8\M
,"/_G
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) (T ^aZuuS
} w 8E,zH
\KEL.}B9E
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[|>r@Aa!
