As Richard mentioned, the scenario that you want to implement is not quite clear. Please provide a more detailed description of your setup, the RadControls for ASP.NET AJAX that you are using and the effect that you want to achieve. Is the control above the RadSlider on your screenshot a RadRotator and if this is the case are you trying to synchronize it with the RadSlider?
If you are still unable to resolve your difficulties please open a support ticker
and send a simple, runnable project
that isolates your case so that I can examine it locally and provide a more to the point answer.
