Unfortunately I am not sure what you need to implement. Can you please elaborate on your requirement a bit more? Specifically it would help us to see a snapshot of what you need to display in the trackball.
However, if your goal is to define a GridView
component and display it within the TrackBallInfoControl
, then you will have to manually update its ItemsSource
. For that purpose you can add a handler for the ChartTrackBallBehavior TrackInfoUpdated
event and traverse the DataPointInfos
collection its arguments expose.
I attached a sample where I defined a business collection of items that should be displayed within a RadGridView
in the TrackBallInfoControl
. I update that collection in the ChartTrackBallBehavior_TrackInfoUpdated
event handler. Please have a look at this approach and let me know if it works for you.
