Remarks

UI_PKEY_Categories is used by an application to query the categories that are used to group related items in a gallery control.

The property value is an IUICollection object where each item in the collection represents a category.

Each item in this IUICollection must implement IUISimplePropertySet to expose the read-only properties associated with the item, such as the label or image.

To add or delete items in a gallery control at run time, use the various methods of IUICollection.
