There is an approach that will fit your case better. However, the API to be used is currently internal. We will need some time to decide what part of it we want to expose. This change is also connected to providing samples and documentation for the new functionality.
We will do our best to expose the API for the Service Pack that will be released at the end of July. We will also decide what scroll bar properties / scroll bar events / viewport events should be exposed for the SP.
We hope this will suit your needs.
