private void Chart_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
    {
        var originalSource = e.OriginalSource as DependencyObject;
        if (originalSource is Ellipse)
        {
            ContextMenu contextMenu = new ContextMenu();

            contextMenu.Items.Add("Lookup Details in Grid");
            contextMenu.Items.Add("Lookup Defect Info");

            runTrendChart.ContextMenu = contextMenu;

        }
        else
            runTrendChart.ContextMenu = null;
    }

Instead of adding just strings to ContextMenu Items collection you should add a new MenuItem element:

contextMenu.Items.Add(MenuItem() 
{
Header = "Lookup Details in Grid",
Command = ANY_COMMAND_YOU_WANT
});

I don't see the reason why you are adding this MenuItems in MouseRightButtonDown handler instead of XAML, but this should solve your problem.

Edit If you don't want to use a Command the MenuItem has a Click event to which you can add an event handler.
