How to clear the children of a tree node

[cal555]

Hi,

I have a tree that has topics, so for example in the following:

Aouto type
Car
Suv
Sports car
Van
Truck
Motor cycle
Aircraft
Helo
Jet
Plain

I notice that If I colllaps a level it still is retaining the children structor in memory, where the first time through it builds them.
I need that if I collapse the car node it to totaly clears its children and rebuilds them again on expansion. Is there a tree function or something that would do this? I think the answer is in using Tree.Nodes.Remove some how, but I am not sure how I would use it here.

Thank you

You would use it along with the Collapse event.
