r'/&{?Je/
日期格式设定 8Wqh 8$

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) X6)%2TwO

9.获取错误信息并到指定页面 DA]<30w
= >CADTU
不要使用Response.Redirect,而应该使用Server.Transfer BbsgZ4
-FpZZ8=,M2
e.g xY4g2Q
J
// in global.asax =1sGT;>
protected void Application_Error(Object sender, EventArgs e) { q)te/J@
if (Server.GetLastError() is HttpUnhandledException) )Q= EmZbJz
Server.Transfer("MyErrorPage.aspx"); <` [o|>A Z
!l NCuR/T
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) mh#NmW>n
} -UY5T@as
!iv6k~.e'2
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 nVB.sab
