    Hello Vinod,

    Indeed your observations are correct -- the official version of the control released with the Q1 2010 release did not support interactivity features (tooltips, click events) in zooming / scrolling scenarios.

    Note, however, that our developers were able to address this limitation shortly after the release, so you can now download the latest weekly internal build from your Client.Net account and you will be able to use tooltips in zooming / scrolling scenarios as well.

    Best wishes,
    the Telerik team

    Hi Rakhi,

    We are a bit unsure what exactly you are looking for but you can find the RadChart filtering example here and the help topic here.

    If the problem persists, we would ask you to paste the control declaration and the data model you are using so we can advise you properly how to proceed.

    All the best,
    the Telerik team

    Hello Janaki,

    I suggest you download the latest version of our controls. We have a new control - ChartView. It is actually a set of controls, such as RadCartesianChart. The RadCartesianChart supports both zooming, scrolling and tooltips - and yes, these features all work at the same time.
