By default, Boolean properties are represented in a UI via a check box:

BooleanPropertyEditor_1

When the CaptionsForBoolValuesAttribute is applied to a property, it is displayed via a combo box containing the specified captions:

BooleanPropertyEditor_2

The attribute's parameter values are assigned to the IModelCommonMemberViewItem.CaptionForFalse and IModelCommonMemberViewItem.CaptionForTrue properties of the Application Model's BOModel | <Class> | OwnMembers | <Member> node. Additionally, these attribute values are set for the same properties of the Views | <ListView> | Columns | <Column> and Views | <DetailView> | Items | <PropertyEditor> nodes. You can can set other values to these properties, in the appropriate node.

To add images to the combo box, you can apply the ImagesForBoolValuesAttribute:

BooleanPropertyEditor_3
