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.
If a node data object implements System.ComponentModel.INotifyPropertyChanged and if the key is a simple property on the data as reflected by the value of ToNodesPath, the model will automatically call this method. Otherwise, you need to do so immediately after the value of FindToNodeKeysForNode has changed.
This raises a Changed event with a value of ModelChange.ChangedToNodeKeys.
