Hi users of the popular treeview control!

I have a situation where I need to delete the last three immediate subnodes of a node. Say Node A has thre children a1, a2, a3, a4 in that order. I want to remove a4, a3 and a2 in that order so that A remains with one child - a1.

Does someone know how I can move from the currently selected node and skip down to it's children perform a delete and move up? Or any way of achieving this please out there?

Thanks.

Mathias
