8.关于日期格式 -Owb@Nw
7Jd&9&O U
日期格式设定 J6ed
DataFormatString="{0:yyyy-MM-dd}" t<RPDQ>
Kaaz,C.$^
我觉得应该在itembound事件中 A

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) M

9.获取错误信息并到指定页面 t:v>W8N53
2izBB,# "
不要使用Response.Redirect,而应该使用Server.Transfer M@p<L
VP
?6L8#"=
e.g ?^LG>GgV
// in global.asax d`%7Pk
protected void Application_Error(Object sender, EventArgs e) { b!teSf
if (Server.GetLastError() is HttpUnhandledException) .[1@wW&L
Server.Transfer("MyErrorPage.aspx"); *P&lAyt6
g>`D!n::n
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) B__e*d:)!m

Hg 4.
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 9xE_Awlc85
