using System.Drawing;

public class MyButton : ButtonBase, IButtonControl
{
    private DialogResult myDialogResult;

    public MyButton()
    {
        // Make the button White and a Popup style
        // so it can be distinguished on the form.
        this.FlatStyle = FlatStyle.Popup;
        this.BackColor = Color.White;
    }
        
    // Add implementation to the IButtonControl.DialogResult property.
    public DialogResult DialogResult
    {
        get
        {
            return this.myDialogResult;
        }

        set
        {
            if(Enum.IsDefined(typeof(DialogResult), value))				
            {
                this.myDialogResult = value;
            }
        }	
    }

    // Add implementation to the IButtonControl.NotifyDefault method.
    public void NotifyDefault(bool value)
    {
        if(this.IsDefault != value)
        {
            this.IsDefault = value;
        }
    }

    // Add implementation to the IButtonControl.PerformClick method.
    public void PerformClick()
    {
        if(this.CanSelect)
        {
            this.OnClick(EventArgs.Empty);
        }
    }
}

Remarks

This method is called for the button that has focus, or for the default button (if no other button has focus) when the user presses the ENTER key. This method is also called when the user presses the ESC key if the button is set as the cancel button.
