I am afraid that the RadDockZone does not support the features you require out-of-the-box. It could be possible to achieve the resizing and dragging of the dock zones by placing them in the content of RadDock controls that will have dragging and resizing enabled. Nevertheless, this would require writing a lot of custom code to handle the behavior you described, which is outside the scope of our support system.
Feel free to contact us again if you have any questions about the implementation or the configuration of the dock control.
