By design when the RadDock control is pinned its position
attribute is automatically set to fixed
while when the dock is not docked in a zone and it is not pinned its position is set to absolute
. The position:fixed
is basically the same as position:absolute
except that when the user scrolls the page, the element does not scroll with it, it just says exactly where it was. That is why, the behavior you observe is the expected behavior of the control by design.
