public void DoChildNodeKeyRemoved( 
   NodeType nodedata,
   NodeKey childkey
)

Parameters

nodedata

the modified node data

childkey

the key for the removed child 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 child keys implements System.Collections.Specialized.INotifyCollectionChanged the model will automatically call this method. Otherwise, you need to do so immediately after the value of FindChildNodeKeysForNode has changed.

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