8.关于日期格式 YUIi;
@|%2f@h
日期格式设定 IB7E}56l
DataFormatString="{0:yyyy-MM-dd}" &JI8]JmU)

我觉得应该在itembound事件中 ^`>/.gL
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) !I

9.获取错误信息并到指定页面 e@OX_t_
iW /}#
不要使用Response.Redirect,而应该使用Server.Transfer "6?0h[uff
tC9n
k5~
e.g & 9 ?\b7
// in global.asax ;BIY^6,7e
protected void Application_Error(Object sender, EventArgs e) { qm o9G
if (Server.GetLastError() is HttpUnhandledException) 0=E]cQwh
Server.Transfer("MyErrorPage.aspx"); <HVt
V9R
l2P=R)@{
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `lt"[K<
} v-_e)m^
=zKM=qba
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 pD#rnp>WWt
