Hide TreeView root node in WPF

Question

Hello,

Can someone tell me how to hide the root node of a TreeView in WPF/Silverlight? I would still like to display hierarchical data and to be able to expand collapse nodes except for the root node (which shouldn't be displayed at all).

Regards,

Xam

Answer 1

You can create a DataTrigger that makes the root node collapsed

Answer 2

Do you need to have a single root node?

If not you could create all your items at the top level.

  <TreeViewItem Header='First'>
    <TreeViewItem Header='sub' />
  </TreeViewItem>
  <TreeViewItem Header='Second'>
    <TreeViewItem Header='sub' />
  </TreeViewItem>
  <TreeViewItem Header='Third'>
    <TreeViewItem Header='sub' />
  </TreeViewItem>
</TreeView>
