I am using DVF 6.6B to process several Treeview events. The std Treeview control allows checkboxes to be one of each tree items active states. However, I have been unable to find the corresponding treeview notification message. The TVN_SELCHANGED event is useless because this event is independent of the checkbox state event. The NM_CLICK event provides some hope, but it only tells me which treeview control the user clicked in, not which treeview item within the treeview control. I suppose I could capture mouse movements and send a TVM_HITTEST message to see if the mouse was within the state icon region, but that seems a rather roundabout and possibly inaccurate approach.
Thanks for any help!
