8.关于日期格式 BS7J#8cu
J>%t<xYf4
日期格式设定 aD ESr?
DataFormatString="{0:yyyy-MM-dd}" .oR3Q/|k]
[N:BM% FQ
我觉得应该在itembound事件中 6Y7H|>g)
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) <GF @L
#6W,6(#^#
9.获取错误信息并到指定页面 sx5r(0Z
SY1GR n
不要使用Response.Redirect,而应该使用Server.Transfer 0^#DNq*NQ
:<GfET Is
e.g >vujZw_0>
// in global.asax jK3\K/ob(
protected void Application_Error(Object sender, EventArgs e) { /\J|Uj
if (Server.GetLastError() is HttpUnhandledException) *vnXlV4L
Server.Transfer("MyErrorPage.aspx"); xmr|'}Pt[
p)3nyN=|_
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) #mLuU
} ?2ItB `<(
ntGq"
o
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 })[($$f/

10.清空Cookie AmcC:5
Cookie.Expires=[DateTime]; Q\9K2=4
Response.Cookies("UserName").Expires = 0 wqy^8N[K]
