User controls in winform application with mvp pattern

I'm developing winform application using MVP pattern. There are some user controls in my application which were created before. My question is: should I use MVP inside these controls? That is, do I have alter thier?

Solution

The reason is the communication among user-controls should be consistent. eg, do you want it to look like this:

Or more elegant and uniform:
