A SmartItem is an item which is contained within a SmartControl or another SmartItem. Each SmartItem automatically handles the appropriate events and reacts according to a logical, predefined behavior.

Preferred SmartItems

Each SmartControl (or SmartItem) has a selection of preferred SmartItems. These are the SmartItems which make the most sense to use for a specific SmartControl (or SmartItem). For example, all the preferred SmartItems of the SmartToolBar SmartControl will be tools while all the preferred SmartItems of the SmartStatusBar SmartControl will be panels.. Although via the designer only the preferred SmartItems can be added to a SmartControl, via code, any SmartItem can be added to any SmartControl. 

The following diagram provides a hierarchical view of the preferred SmartItems for each SmartControl:
