Amalgamating the answers from the duplicate question

public class NoFocusCueButton : Button
{
    public NoFocusCueButton() : base()
    {
        InitializeComponent();

        this.SetStyle(ControlStyles.Selectable, false);
    }

    protected override bool ShowFocusCues
    {
        get
        {
           return false;
        }
    }
}

Answer 2

create a new class and inherit class Button, eg

public class OnetsButton : Button
{
    public OnetsButton()
    {
        this.SetStyle(ControlStyles.Selectable, false);
    }
}

I have a solution now, it's not very sexy, but it works. I just added an invisible button to the form and now everytime a button is clicked, I select the invisible button. Works for me.
