title: TreeView: SelectedNode doesnt work for me
body: <p>Im using following code:</p>
  
  <pre><code>TreeNode i = treeView1.SelectedNode;
  
  RefillTree(); //clears the tree and rebuilt it again.
  
  treeView1.SelectedNode=i;
  </code></pre>
  
  <p>However, SelectedNode still remains null, however "i" is correctly referencing.</p>
  
  <p>I would need to select and expand particular node automatically after tree refresh.</p>
  
  <p>Thank you</p>
