Two issues:  (1) it seems that tvntNone is not persisted as CheckType.  I have created some simple trees at design time, and this is not persisted when I re-open the project or when I run the program.  It is OK if I assign the value at run-time.  (2) as a feature request, it would be great if the checkbox could be made tri-state, to allow it to show a grey square if some of the child nodes were checked, but not all.


We have fixed issue one, the next version will address this.
We have added the request for a tri-state to our feature request list.
