Property Value

Type	Description
TreeListNode	A TreeListNode object which represents the previous node in the collection. null (Nothing in Visual Basic) if the current node is the first node in the collection.

Remarks

Nodes are contained within the nodes collections (the TreeListNodes objects). For example, the root nodes are contained within the Tree List’s TreeList.Nodes collection. Each node can have children which are contained within its TreeListNode.Nodes collection. The PrevNode method allows the node prior to the current one in the collection to be obtained.
