title: How to execute code the second a checkbox is checked? C#
body: <p>When I usually work with checkboxes, I check to see if the box is checked with the code below:</p>
  
  <pre><code>if (checkBox1.Checked)
  {    
       Label1.BackColor = Color.Red;
  }
  </code></pre>
  
  <p>This code is usually attached to a button that sets into motion when it's clicked by the user.  This time, however, I want to do something, like change the color of a label, the very SECOND the checkbox is checked by the user.  That is, I don't want to wait until the user pushes some other button to check if the checkbox is checked in order for the label's color to change.  </p>
  
  <p>How do I do this?</p>
