ASP.NET MVP Composition

i just read the article below : https://www.c-sharpcorner.com/UploadFile/vendettamit/simplest-example-of-mvp-design-patter-of-Asp-Net/

I found the idea pretty and i would try to adopt this MVP pattern in a ASP.NET project (unfortunaltely the MVC option is not suitable for my team). But i am not sure how to handle composition, usually with the ASCXs components i can "define" my custom user controls, and so reuse code.

Not clear to me how to achieve this with MVP pattern
