Put this onto your form, and expand the root node. Mousemove will be fired, and you will start a drag operation if you don't check the position.

void Tree2_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    // Note this may not work as desired if you have TreeView(s) embedded in your TreeView :)

    TreeView tv = e.Source as TreeView;
    if (tv != null)
    {
        lastMouseDown = e.GetPosition(this);
        readyToDrag = true;
    }
}
