title: Does WPF have mouse wheel scrolling up and down event
body: <p>I checked msdn. For event related to <strong>mouse wheel</strong>, there is only one option -- UIElement.MouseWheel</p>
  
  <p>What I want to do is listening to mouse wheel scrolling forward(up) and backward(down) event.</p>
  
  <p>Note: <strong>Not</strong> <strong>clicking</strong> the middle wheel button.</p>
