TreeView in WPF3.5 SP1 has a Bug. When you select a tree node, the node moves up or down to the top or bottom of the tree area.

Reproduction steps:

1. Select a node with the mouse.

2. Select other visual controls to ensure that the TreeView loses focus.

3. Move the selected node in step 1 to an invisible position with the mouse scroll.

4. select another node with the mouse.

The cause is that there is a problem with the FrameworkElement. bringlateral view () method.

This Bug has been fixed in WPF4.0.
