title: Why Is My Event Handler Considered as Having No References?
body: <p>I coded an event handler for a ComboBox's dropDownClosed event:</p>
  <p><a href="https://i.stack.imgur.com/fYWpQ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fYWpQ.png" alt="enter image description here" /></a></p>
  <p>...but it show &quot;0 references&quot;:</p>
  <p><a href="https://i.stack.imgur.com/zhxYT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zhxYT.png" alt="enter image description here" /></a></p>
  <p>Why would that be? The button click events do display 1 reference...</p>
