It will possible to manually invoke the saving and loading of the dock state when the built-in dock state persistence is used in order to avoid the automatic saving and loading of the state on each postback.
When a RadDock control is dragged to the bottom of a page, the page will start scrolling.
Request new properties for the RadDockZone to allow the display of a message, image, or style when no docks are present in the zone along the lines of the EmptyMessage property of the RadInput control. The properties could be: "EmptyZoneMessage", "EmptyZoneImage" and "EmptyZoneCssClass". See the following thread from 2010 where a solution to this was discussed: http://www.telerik.com/forums/empty-raddockzone-message
The RadDock will be moved with the cursor when the scroll wheel is used while dragging the control.
