Remarks

Use the CopyFrom method to duplicate the style properties of the specified Style object in the TreeNodeStyle object that calls this method.

Note

All properties in the current TreeNodeStyle object are replaced by the corresponding properties in the specified Style object.

To copy style properties without replacing any values that have already been set, use the MergeWith method.
