title: How to check if the resize is still in progress with OnResize event?
body: <p>I need to redraw a control after it was resized and not while it is being resized because it takes a lot of time to redraw a control and it wastes a lot of resources.</p>
  
  <p>My control inherits <strong>Control</strong> class and I'm overriding the <strong>OnResize</strong> event. </p>
  
  <p><strong>PS:</strong> OnSizeChanged is absolutely the same</p>
