In regards to the ToolWindows filling the RadDock area, please refer to this article

As to the second part of your inquiry, you can subscribe to the DockStateChanged event of RadDock and if all DockWindows have their DockState set to AutoHide, modify the layout of RadSplitContainer as demonstrated here
