title: Get sender name event handler
body: <p>I hope the name gives justice to my question... So, I just started making a memory game, and there are 25 checkbox buttons which I am using to show the items.</p>
  
  <p>I was wondering whether there was a way to tell from either the EventArgs or the Object what button it was sent from if each button used the same event handler.</p>
  
  <pre><code>private void checkBox_CheckedChanged(object sender, EventArgs e)
      {
          checkBox = Code which will determine what checkBox sent it.
          if (checkBox.Checked)
          { Box.ChangeState(checkBox, true); }
          else { Box.ChangeState(checkBox, false);}
      }
  </code></pre>
