问题
when I extend an asp.net control and place the extended control class in, say, Applicaton_code
(without specifying the namespace) how do i register the control to use it on a webpage?
what assembly name and namespace should be specified?
回答1:
use :
<%@Register TagPrefix="local" Assembly="App_Code" Namespace="Controls" %>
Also, you HAVE to defines a namespace where to put your controls (from memory, when adding class to App_code, no namespace is generated by default).
namespace Controls {
public class control1 : WebControl {
}
}
and then , in the aspx file
<local:control1 runat="server", id="youreluckyitworks" />
