日期格式设定 -Ekf T_

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) |?MD>Pez

9.获取错误信息并到指定页面 nr(C*E
IlI5xkJ(
不要使用Response.Redirect,而应该使用Server.Transfer FP0GE
> %Hw008
e.g A_2lG!!

// in global.asax Zw%:mZN
protected void Application_Error(Object sender, EventArgs e) { !|9k&o
if (Server.GetLastError() is HttpUnhandledException) { ~(XO@;b
Server.Transfer("MyErrorPage.aspx"); s&wm^R
77 Z:!J|
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) M9(lxu y1
} +@7c:CAy(
r&:yZN
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 AI,E9
