title: Select subitem in Listview and change value
body: <p>I have a listview in the "details" mode that looks something like:</p>
  
  <pre><code>#################
  Name  #  Property
  #################
  #Itm1 # Subitm1
  #Itm2 # Subitm2
  #################
  </code></pre>
  
  <p>Very simple, but the problem I am running into is I cannot select "Subitm1" in the list at runtime. I can select and highlight every item in the first column, but clicking on any item in the second column does nothing (I would expect it to highlight the item like in the first column). </p>
  
  <p>Specifically, I'm trying to add the ability for a user to be able to double-click a sub-item and change it's value directly at the listview. Is there a specific setting I'm missing here?</p>
