title: C# - Listview Item selection queues
body: <p>I have a listview and a button to remove items from that listview. The button needs to be disabled when they don't have any items selected, but enabled when they do. I've tried a different combination of events, but can't find one to properly disable the button... </p>
  
  <p>When I disable the button when the listview loses focus, I can't remove the item because in order to click the button, they need to click outside the listview.. </p>
  
  <p>I'm hoping someone who's more experience in Visual Studio can help me find the correct combination of listview events to enable and disable the button according to whether or not they have an item selected.</p>
