Remarks

This is always set to 1. For the SetImage method, you can either use the full name of this field or the constant value of 1 to identify the collapse image.

Any of several parts of the graphical interface of the component can be customized. This one identifies the image in the hierarchy display that is clicked to collapse the hierarchy. Refer to Customizing the Graphical Interface for more information.
