8.关于日期格式 x H=15JY1W
q
&{<HcP
日期格式设定 7Nk|9t
DataFormatString="{0:yyyy-MM-dd}" 0b
n%L~KU

我觉得应该在itembound事件中 Y.tT#J^=
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) uPYH3<

9.获取错误信息并到指定页面 h9}*_qc&kV
FINHO058^Y
不要使用Response.Redirect,而应该使用Server.Transfer nfGI4ZE
q TN)2G
e.g gVR]z9
// in global.asax H=f|X<8
protected void Application_Error(Object sender, EventArgs e) { <;~u@^>
if (Server.GetLastError() is HttpUnhandledException) {i8zM6eC
Server.Transfer("MyErrorPage.aspx"); G-RDQ
v3XM-+Z4
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) b.\xPb
} f^u-Myk
uZJfIC<>
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 d(ypFd9z

10.清空Cookie 2=0HQXXrq
Cookie.Expires=[DateTime]; w=rD8@
Response.Cookies("UserName").Expires = 0 |K-`
