1. Beispiel

 TreeViewItem root;
 tree.Items.Clear();
 root = new TreeViewItem();
 root.Header = "root";
 root.Foreground = Brushes.Red;
 root.IsExpanded = true;
 tree.Items.Add(root);

 TreeViewItem kind = new TreeViewItem();
 kind.Header = "Natalie";
 kind.Foreground = Brushes.Blue;
 root.Items.Add(kind);

 kind = new TreeViewItem();
 kind.Header = "Kevin";
 kind.Foreground = Brushes.Blue;
 root.Items.Add(kind);
