property of the RadDock is used to pin the dock to the page relative to page's top-left corner, when the the DockMode
property is set to Floating.
So by default if the Pinned
property is set to true the dock will be pinned at the (Top=0px, Left=0px) position, if no top-left position is specified.
To achieve the desired behavior, instead of using Pinned=true, our suggestion is to place the dock in a RadDockZone and set its EnableDrag property to false. This will cause the dock not to be draggable.
