Re: Restore scroll position of a DIV over a postback

JezB

Well, it did work partly : if the control which causes the postback is in
the scrollable DIV it does rescroll far enough to focus on it if I turn
smart navigation on, but not EXACTLY to the same scroll position (so user
sees it jump from middle to bottom, for example). Also, if the control which
caused the postback was outside the scrollable area it always scrolled
itself back to the top. Therefore I had to come up with a better solution.
