Just thinking aloud, but supposed you intercepted the scroll events and calculated whether the user was allowed to move that way and apply preventDefault if not?

I appreciate the responses, but I do not believe this will accomplish what I need. Masking is the closest so far, but the scroll bars create a problem. Simply making items hidden, does hide viewable items, but leaves the container with a lot of blank space. Essentially, I want to override the index or whatever values the scrollbar uses to determine the top and bottom of the container, and set my own values. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Manish Jethani" <manish.jeth...@...> wrote: > > On Tue, Dec 23, 2008 at 5:41 AM, jmfillman <jmfill...@...> wrote: > > > I have a Canvas that with a height of 3000.
