Parameters
- nodedata
This is used for model update, when the model data has changed and the model itself needs to be updated to reflect those changes. Note that this method is universal, because it can only assume the node data is of type System.Object. The corresponding methods in the generic model classes operate on a specific node data type.
If the NodesSource collection implements INotifyCollectionChanged, the model will automatically call this method. Otherwise, you need to do so immediately after the NodesSource has been diminished.
