Scroll selected TreeView node into view

node.EnsureVisible();

for example:

if(treeView.SelectedNode != null) treeView.SelectedNode.EnsureVisible();

(see MSDN)

I also had issues with this and figured out that treeview.ExpandAll() ignores the EnsureVisible() effect and avoids the scrolling to the node position.

Just call EnsureVisible() after ExpandAll() if you want a full expanded tree with the scroll on the node you've selected.
