Release 10.1A: OpenEdge Development:
ADM Reference

> ## NextNodeKey

> Unique code to be used for the Key attribute of the Tree view.

> Data type: CHARACTER

> Notes:

> - Read only.

> - You cannot begin a key for a node with a number in Microsoft TreeView. Therefore, the prefix xcNodePrefix is used.

> - The key is used as the sort field when adding nodes. Therefore, the string “999999999999” is used to guarantee a valid sort order.
