8.关于日期格式 8 ?xE6
(>LF(ll
日期格式设定 A#e%^{q$
DataFormatString="{0:yyyy-MM-dd}" LQ@"Xe]5
;YaQB#GK%
我觉得应该在itembound事件中 k
R?qb6
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) y6g&Y.:o

9.获取错误信息并到指定页面 ^
gdaa>L
)*u8/U
不要使用Response.Redirect,而应该使用Server.Transfer P0;n9>g
A @i
e.g pIc#L>{E
// in global.asax 9Gvd&U
protected void Application_Error(Object sender, EventArgs e) { '+@=ILj>
if (Server.GetLastError() is HttpUnhandledException) akmkyrz '&
Server.Transfer("MyErrorPage.aspx"); #$.;'#u'so
&sl0W-;0
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) j`EXlc~
} H%[eV8
P9R9(quI
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 v&6-a* <Z
