title: TreeView won't populate
body: <p>I got a tree view what won't populate,
  when I add Nodes they don't show up in the UI but they are in the object,
  and when I set in Visual Studio the nodes they show up,</p>
  
  <p>I tried everything</p>
  
  <pre><code>TreeView.Refresh();
  TreeView.BeginUpdate();
  TreeView.Focus();
  </code></pre>
  
  <p>Im annoyed by it, I worked many times with the TreeView but this never happend?</p>
  
  <p>UPDATE: </p>
  
  <p>I add Nodes with this code:</p>
  
  <pre><code>PathSelectTree.Nodes.Add("hello?");
  </code></pre>
  
  <p>UPDATE 2:</p>
  
  <p>When I add the nodes before </p>
  
  <pre><code>InitializeComponent();
  </code></pre>
  
  <p>it works...</p>
  
  <p>UPDATE 3:</p>
  
  <p>the add node is in the form load event but I also tried a button click event</p>
