问题 Is it possible without encapsulating these controls in aspx files? The Register tag makes me think that it is not. 回答1: You can't call ascx page directly, they can't serve any html without added to aspx or render then dynamically in response to any page/handler. 回答2: One possible way would be to have a generic aspx stub page that acts as a host to the ascx in the normal web forms way make a callback to the that page using JQuery's $.ajax() method with some arguments to denote what ascx
