Synchronizing mouse events across charts

Hello

Im doing mutual crosshair, like this

static class ModifierFactory
{
    public static ModifierGroup Crosshair () 
    {
        SeriesSelectionModifier SelSerMod = new SeriesSelectionModifier() { SelectedSeriesStyle = new Style(typeof(BaseRenderableSeries)) { }, ExecuteOn = ExecuteOn.MouseRightButton };
        LegendModifier LegendModifier = new LegendModifier() { GetLegendDataFor = GetLegendDataFor.SelectedSeries, };

        MouseWheelZoomModifier MouseWheelZoomModifier = new MouseWheelZoomModifier() { ReceiveHandledEvents = true };
        ZoomPanModifier ZoomPanModifier = new ZoomPanModifier() { ReceiveHandledEvents = true };
        ZoomExtentsModifier ZoomExtensModifier = new ZoomExtentsModifier() { ReceiveHandledEvents = true, ExecuteOn = ExecuteOn.MouseDoubleClick };
        CursorModifier CursorModifier = new CursorModifier() { ReceiveHandledEvents = true };
        RolloverModifier RolloverModifier = new RolloverModifier() { ReceiveHandledEvents = true };

        return  new ModifierGroup(CursorModifier, MouseWheelZoomModifier, ZoomPanModifier, ZoomExtensModifier) {  MouseEventGroup = "MyGroup" };
    }

    public static ModifierGroup Rollover ()
    {
        SeriesSelectionModifier SelSerMod = new SeriesSelectionModifier() { SelectedSeriesStyle = new Style(typeof(BaseRenderableSeries)) { }, ExecuteOn = ExecuteOn.MouseRightButton };
        LegendModifier LegendModifier = new LegendModifier() { GetLegendDataFor = GetLegendDataFor.SelectedSeries, };

        MouseWheelZoomModifier MouseWheelZoomModifier = new MouseWheelZoomModifier() { ReceiveHandledEvents = true };
        ZoomPanModifier ZoomPanModifier = new ZoomPanModifier() { ReceiveHandledEvents = true };
        ZoomExtentsModifier ZoomExtensModifier = new ZoomExtentsModifier() { ReceiveHandledEvents = true, ExecuteOn = ExecuteOn.MouseDoubleClick };
        CursorModifier CursorModifier = new CursorModifier() { ReceiveHandledEvents = true };
        RolloverModifier RolloverModifier = new RolloverModifier() { ReceiveHandledEvents = true };

        return new ModifierGroup(RolloverModifier, ZoomPanModifier, MouseWheelZoomModifier, ZoomExtensModifier) { MouseEventGroup = "MyGroup" };
    }

    public static ModifierGroup SimpleModifier() 
    {
        SeriesSelectionModifier SelSerMod = new SeriesSelectionModifier() { SelectedSeriesStyle = new Style(typeof(BaseRenderableSeries)) { }, ExecuteOn = ExecuteOn.MouseRightButton };
        LegendModifier LegendModifier = new LegendModifier() { GetLegendDataFor = GetLegendDataFor.SelectedSeries, };

        MouseWheelZoomModifier MouseWheelZoomModifier = new MouseWheelZoomModifier() { ReceiveHandledEvents = true };
        ZoomPanModifier ZoomPanModifier = new ZoomPanModifier() { ReceiveHandledEvents = true };
        ZoomExtentsModifier ZoomExtensModifier = new ZoomExtentsModifier() { ReceiveHandledEvents = true, ExecuteOn = ExecuteOn.MouseDoubleClick };
        CursorModifier CursorModifier = new CursorModifier() { ReceiveHandledEvents = true };
        RolloverModifier RolloverModifier = new RolloverModifier() { ReceiveHandledEvents = true };

        return new ModifierGroup(ZoomPanModifier, MouseWheelZoomModifier, ZoomExtensModifier) { MouseEventGroup = "MyGroup" }; 
    }
}



SciChartSurface FirstChart;
SciChartSurface SecondChart;
...
...
FirstChart.ChartModifier = ModifierFactory.Crosshair ();
SecondChart.ChartModifier = ModifierFactory.Crosshair ();

But it is not mutual, every chart get single crosshair
Mb its because i got winForms project, which load wpf dll and open a wpf window ?
