title: ListBox.SelectedIndexChanged - can you determine if it was user initiated?
body: <p>My question is similar to this: <a href="https://stackoverflow.com/questions/905447/how-to-prevent-listbox-selectedindexchanged-event">How to prevent ListBox.SelectedIndexChanged event?</a>, but I want to ask it a different way.</p>
  
  <p>Is there a simple way to determine if the 'SelectedIndexChanged' is coming from the user as opposed to initiated through code (e.g. ListBox.SelectedIndex = x)?</p>
