Public Sub DoMemberNodeKeyAdded( _
   ByVal nodedata As NodeType, _
   ByVal memberkey As NodeKey _
) 

public void DoMemberNodeKeyAdded( 
   NodeType nodedata,
   NodeKey memberkey
)

Parameters

nodedata

the modified node data

memberkey

the key for the added "member" node data

This is used for model update, when the model data has changed and the model itself needs to be updated to reflect those changes.

If the list of "member" keys implements System.Collections.Specialized.INotifyCollectionChanged the model will automatically call this method. Otherwise, you need to do so immediately after the value of FindMemberNodeKeysForNode has changed.

This raises a Changed event with a value of ModelChange.AddedMemberNodeKey.
