DoGroupNodeChanged Method (GraphModel<NodeType,NodeKey>)

This should be called when a node data's membership in a group may have changed.

Syntax

public void DoGroupNodeChanged( 
   NodeType nodedata
)

Parameters

nodedata: the modified node data

Remarks

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 GroupNodePath, the model will automatically call this method. Otherwise, you need to do so immediately after the value of FindGroupKeyForNode has changed.

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