Need help to create this control (some sort of 'node' cell)

Hello everyone!

I am not new to this forum, but I have lost my old account ...

So:
Greetings to all again !!

My current problem is the following:

I'm trying to create some sort of control that I can add to a project, rather than building it on Form directly.



What I would like to do is what is described in the attached drawing



--- --- ---

Obviously, I have to implement functions, which allow me to load and / or save the dates I enter in the fields!
(But that's something I can see later ...
For now I'd be interested in being able to create Control first!)


Can anyone weapons any indication !?

Thank you
