To specify a category for a bar item, use the BarItem.CategoryName or BarItem.Category property. Ensure that the category assigned to the bar item exists in the BarManager.Categories collection.

The category’s name must be unique. To provide display captions for categories, use the BarManagerCategory.Caption property.
