The ProvideChildNodes method of the IOlapAddIn interface adds nodes under existing nodes to the Analysis Manager tree pane.
Sub ProvideChildNodes(ParentNode As OlapTreeNode, OlapTreeNodes As OlapTreeNodes)
ParentNode
The OlapTreeNode object that is currently selected or being expanded in the tree pane display.
OlapTreeNodes
An empty collection of OlapTreeNode objects. The add-in populates this collection with the child OlapTreeNode objects to be created under ParentNode.
This method responds to a request that the add-in populate an OlapTreeNodes collection. This collection is made of nodes that belong to the OlapTreeNode object that is currently selected or being expanded. Your add-in uses this method to add nodes to the tree pane. An add-in uses this method only if it needs to add OlapTreeNode objects to the tree pane.
