Adolfo Moro, I’m not sure if this is it, but once I made a "list of controls". I have an example, but it’s on VB6 and only has a Textbox in which I added several new properties to it.
ACTIVEX CONTROL TEXTBOX - USER CONTROL
A "inherited" Textbox control that restricts Text allowing only numbers if it is configured in Properties, manages whether it received focus by colors and makes other properties and a custom event.

What you can do is create a "User Control" of yours by adding all the components you created and have it called every time you need one more line. Below is an example in C# of Macoratti.
C# - Creating Custom Controls (User Control)
In this article we will see how we can create custom controls in the C language#.
When you are developing your Window Forms program, the form designer is where you organize your controls and decide what look you want to give them. There is also a designer for user controls, the User Control Designer, which allows you to decide how user control will be.
So User Control is not programming technique?
