Best way to delete permanently a control from the parent container

Question

Is this an acceptable way to remove a custom control from the parent container control from inside the custom control? In my case the parent container control and the child control both are panels. Could you suggest me a better way.

protected override void OnKeyDown(KeyEventArgs e)
{
            base.OnKeyDown(e);
            if (e.KeyCode == Keys.Delete && this.Focused == true)
            {
                    this.Parent.Controls.Remove(this);
            }
 }
