Public Sub DoNodeCategoryChanged( _
   ByVal nodedata As NodeType _
) 

public void DoNodeCategoryChanged( 
   NodeType nodedata
)

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

This raises a Changed event with a value of Northwoods.GoXam.Model.ModelChange.ChangedNodeCategory.
