I am working on a Visual Web Part that requires the creation of a custom control. I am trying to add a custom control to the same assembly as the Visual Web Part, and register the control as:
<%@ Register TagPrefix="cus" Namespace="SomeCustomControlNameSpace" %>
When I try to access this error on startup:
Unknown server tag 'cus: ControlName'.
Do I need to make any entry in Web.Config for this?
Any ideas?
