This collection stores regular and standalone bar dock controls that provide docking functionality for bars.
When a BarManager component is created, four dock controls are automatically created and added to the DockControls collection. Each dock control is docked to the side of a container control (form).
StandaloneBarDockControl objects created at design time are added to the DockControls collection automatically. If standalone bar dock controls are created at runtime, they must be added to the DockControls collection manually.
