body: <p>How to make using <code>DevExpress</code>:<br>
    1. <code>TreeView</code> based on the database?<br>
    2. <code>TreeView</code> was synchronized with the database?<br>
        Changed the contents of the line -> the database was updated.</p>
  
  <pre><code>  Dragged the subordinate line to another node -&gt; the database was updated.
  </code></pre>
  
  <p>3. In order to drag-and-drop the <code>TreeView</code> elements between nodes.</p>
  
  <p>How to solve all the problems with the help of "designer" or programming.</p>
  
  <p>On the "1" question, I realized that we need to create a <code>TreeList</code>, and then set the <code>TreeList.ViewStyle</code> property to <code>TreeView</code>.<br>
  So it is written in the documentation  </p>
  
  <p>I created the <a href="https://i.stack.imgur.com/twxQD.jpg" rel="nofollow noreferrer"><code>TreeList</code></a>.</p>
  
  <p>Where can I change the property <code>TreeList.ViewStyle</code>?
