Categories
DXBars for Silverlight allows you to logically organize bar items into categories. A category is a group of items, and each item can belong to only one category. Categories do not impose any restrictions on the items displayed. They are only designed to provide organized access to items via the Customization Window at runtime:
The BarManagerCategory class represents a category. You can add, remove and access individual categories via the BarManager.Categories collection. To assign a category to an item, use the item's BarItem.Category or BarItem.CategoryName property.
