Add similar behavior to a group of WinForms controls

I have a form with 6 buttons. These buttons serve to increase/decrease tha value of the respective textbox. Now I'm trying to "animate" the buttons. I want to get another effect on the button when the mouse is over him.

My form

To do that, I have two diferent images in Resources and I am doing this code:

private void btnHoursDown_MouseHover(object sender, EventArgs e) {
    btnHoursDown.Image = Game_Helper.Properties.Resources.DownHover;
}

private void btnHoursDown_MouseLeave(object sender, EventArgs e) {
    btnHoursDown.Image = Game_Helper.Properties.Resources.Down;
}

This works fine. My question is: it wouldn't be wise to create a class (ButtonBehaviour.cs) and put this code in that class?

So I would have something like this:

ButtonBehaviour buttonBehaviour = new ButtonBehaviour();
private void btnHoursDown_MouseHover(object sender, EventArgs e) {
    buttonBehaviour.buttonDownHover();
}

private void btnHoursDown_MouseLeave(object sender, EventArgs e) {
    buttonBehaviour.buttonDownLeave();
}

And the class should be:

public class ButtonBehaviour {
    public void buttonDownHover() {
       // code
    }

    public void buttonDownLeave() {
       // code
    }
}

How can I create this Class Behaviour and make the buttons adapt this Behaviour?

if one effect should be applied for all buttons, try to add the same event handlers to them

private void btn_MouseHover(object sender, EventArgs e)
{
    (sender as Button).Image = Game_Helper.Properties.Resources.DownHover;
}

private void btn_MouseLeave(object sender, EventArgs e)
{
    (sender as Button).Image = Game_Helper.Properties.Resources.Down;
}

button which raised event is available via sender variable

this way you avoid code duplication for every button. creating a ButtonBehaviour or CustomButton is probably an over-engineering unless you need them in many forms
