[RESOLVED] How to refer to the parent method?

[tinfanide]

        private void btn_OnTop_Click(object sender, EventArgs e)
        {
            this.TopMost = (this.TopMost == false) ? true : false ;
            // how to refer to btn_OnTop?
            btn_OnTop.Text = (this.TopMost == false) ? "On Top" : "Not On Top" ;
        }

Is there a keyword like "this" to refer to btn_OnTop itself inside btn_OnTop?
Thanks in advance.
