V?
日期格式设定 WpP8J1KN[
DataFormatString="{0:yyyy-MM-dd}" 8b8ui

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

9.获取错误信息并到指定页面 f]^(|*6
S7P](F=n#
不要使用Response.Redirect,而应该使用Server.Transfer ]7^OTrZ N

e.g W#$ pt>h)
// in global.asax rtS(iD@B"
protected void Application_Error(Object sender, EventArgs e) { DM/J,q
if (Server.GetLastError() is HttpUnhandledException) Qf6]qJa|
Server.Transfer("MyErrorPage.aspx"); L)H7~.Dj
IxAKIa[HY
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) /(8Usu?g.
} ;+>-uPT/1

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 "[L[*>[9!
