title: How to check the sub nodes in ObjectListView when a head node is checked
body: <pre><code> var branch = TreeListViewAccount.TreeModel.GetBranch(TreeListViewAccount.SelectedObject);
   var childs = branch.Children.Cast&lt;SecurityObject&gt;().ToList();
   TreeListViewAccount.SelectObject(childs.SingleOrDefault(p =&gt; p.Id == soft.Id));
  </code></pre>
  
  <p>This is a code you have posted as an answer to some question, but when i tried this it shows error on <code>SecurityObjects</code> and <code>soft</code>. Actually my question is how can we make an <code>ObjectListView</code> with checkboxes check all the sub nodes when a head node is checked and vice versa can be done.</p>
