    How would I get the X-Y values for a SeriesMapping on mouseover? I'd like to display the values somewhere other than a ToolTip, so enabling tooltips is not my solution. I'm using MVVM, so a codebehind solution, or any UI Element access (i.e. anything requiring System.Windows) is not allowable; however, I would like to be able to use these values in the ViewModel.

    One solution I was considering was using a transparent CustomGridLine with a mouseMoved trigger attached; however, I'm not sure how I would access the SeriesMapping in the ViewModel without needing to use System.Windows to get the Chart itself first.

    Thanks,

    Jake

    EDIT: I found this article, but it requires UIElement access: http://www.telerik.com/help/silverlight/radchart-howto-create-location-crosshair-for-radchart.html. I want to do something similar to this, except cutting out the need for Telerik.Windows namespace and adding snapping to the SeriesMappings on the chart.

    Hi Jake,

    The chart does not support such behavior. The closest approach is the one you have mentioned earlier in your post.

    All the best,
