title: Change button text after click, then change it back after clicking again
body: <p>I am trying to change the text of a Button every time its  clicked.</p>
  
  <p>Button Starts as "ON". When I click it the first time it should change to "OFF", and when I click it again, it should change back to On.</p>
  
  <p>I understand how to change it to "OFF" when clicked, but I am unsure as to how to check for a secondary click so I can change the text back to "ON".</p>
  
  <p>Here is my code so far:</p>
  
  <pre><code>private void OrdersButton_Click(object sender, EventArgs e)
  {
         OrdersButton.Text = " Turn Orders Off";
  }
  </code></pre>
