how can I expand multiple ctreectrls in a splitter window

I have a CSplitterWnd with two panes, A and B. In each pane, there is a CTreeCtrl. I want to be able to expand a node in the B tree control when the user clicks to expand a node in the A tree control. I want to save the user the step of expanding both CTreeCtrl. Sort of a "synchronized" Node Expansion. Is there some way to send a message from the A-pane (or CTreeCtrl-A) to the B-Pane (or CTreeCtrl-B) and tell it to expand?

Zoppo, I think this is going to work. I need to make a few more tests before I "Accept And Award Points". Thank you.

Hi jjjohnaug10,

I'd suggest to add a user-message handler or function in the parent window of the splitter. You then can send that window a message or call that function from the pane window which contains the tree-ctrl when a TVN_ITEMEXPANDED notification was sent from the tree-ctrl.

Implementing this with a user defined message is maybe a little more work but the advantage would be the pane-windows don't need to know about the class/functions of the parent (so they don't need to include the class at all).

In both cases you'd have to pass some data to the called message handler/function, at least which control called it (the left or the right one, so the parent window knows in which control it has to synchronize the item) and the item in question itself.

Hope that helps,
