Creation and editing of dynamic objects

Question

Greetings guys.

I have a "problem" and I wanted some ideas of how I can solve it.

My goal is to make a selection "animation" on several Buttons, so that when one of the Buttons is clicked, a Panel is created on it (and, in case another Button is already selected, it removes the Panel from it).

Let me be more specific. Suppose there is a list of buttons numbered 1 to 3, right? The first Button to be clicked will be Button 1, so a colored Panel will be created on it indicating the selection of the same. After that, Button 3 is clicked so that the Panel created on Button 1 is removed and a new one is created on Button 3.

That’s where my doubt lies. I have a dynamic class for the creation of the Panel on the selected Button, but, I do not know how to perform this "change of positions", made when another Button is selected.

Follows the content of the class:

public class an
{
    public static void a(Button sender)
    {
        Panel p = new Panel();
        p.BackColor = Color.FromArgb(32, 184, 251);
        p.Dock = DockStyle.Right;
        p.Name = "p";
        p.Size = new Size(8, sender.Height);
        sender.Controls.Add(p);
        sender.BackColor = Color.FromArgb(40, 40, 40);
    }
}

The code works well, follows a link with images.

Note that when clicking, the selection of the Button is made with the change of the background color and the creation of a Panel in blue color. Thus, I would like to adapt my code to the "counter-selection" (I believe this term does not exist, hahaha) of the other Buttons.

Therefore, I await answers!

I’m sorry if I wasn’t clear on something.
