WPF Treeview Highlight selected item programmatically

Question

When i rebuild a WPF treeview i want to set the selected item like before the rebuild. Therefore I set the property IsSelected to true and call the method focus() for the treeviewitem. But the background of the selected item is only a pale gray color. How can achieve the standard blue background programmatically. When I click the item with the mouse the item background is blue again.
