Two Radio buttons with different messages when checked

Question

I need use two radio buttons; one is ON and another is OFF.

When we click on any radio button, the application shows me both messages! How do I make it show only the message for the radio button clicked?

    private void rB_OFF_CheckedChanged(object sender,EventArgs e)
    {
    MessageBox.Show("You clicked OFF");
    }

    private void rB_ON_CheckedChanged(object sender,EventArgs e)
    {
    MessageBox.Show("You clicked ON");
    }

Answer 1

because, either the radioButton turns true or false, it just trigger the checkedChanged event, so you need to do this.

private void rB_OFF_CheckedChanged(object sender,EventArgs e)
    {
      if (rB_OFF.Checked == true)
      {
        MessageBox.Show("You clicked OFF");
      }
    }

    private void rB_ON_CheckedChanged(object sender,EventArgs e)
    {
      if (rB_ON.Checked == true)
      {
        MessageBox.Show("You clicked ON");
      }
    }
