Do you have any example using drill down on RadChart with WPF and Prism. I'm particular interested when I click on the Chart area to drill down that I'm able to capture and publish an event. I know I can use ItemClick in my view.xaml.cs but then I would need to get a reference to EventAggregator and RegionManager,in view.xaml.cs, in order to publish an event. I prefer to capture the click event in my viewModel.cs where I have a reference to EventAggregator and RegionManager but how do I wire up the click event in xaml to go to my viewModel.cs. I'm using version RadControl Q2 2010.
