    WPF / Silverlight: Integrating RadChart and RadContextMenu Controls

    One common request that we are receiving recently is how to integrate the RadChart and RadContextMenu controls so they play nicely together. A typical real-life scenario would probably require that each ChartItem should display different (context-specific) set of menu items. In order to address the increased interest in this functionality we decided to add a new integration example for the Q1 2010 release but for those of you that need something working right now, here is a quick overview of the required steps to add context-specific menu to Bar series items in RadChart (this can be applied to any series...
