8.关于日期格式 SQ1.jcWW[
JC_Y#kN@z
日期格式设定 tTLD6#
DataFormatString="{0:yyyy-MM-dd}" ;Bat!K7W
a:XVu0`(
我觉得应该在itembound事件中 tUDOL-Tv
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Og Y4J|<

9.获取错误信息并到指定页面 '0p 5|[ZD
py]m^)yc
不要使用Response.Redirect,而应该使用Server.Transfer c'vxT<8fWW
(es+VI2!&C
e.g ic%<39
// in global.asax +5JCbT@y
protected void Application_Error(Object sender, EventArgs e) { }f+If{
if (Server.GetLastError() is HttpUnhandledException) l|/h4BJ'
Server.Transfer("MyErrorPage.aspx"); 2+s_*zM-
zy"L%i
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 4askQV &hj
} "
2Dz5L1v
dpDVEEs84
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 N&]v\MjI62
