Series Selection Modifier Issues

Hello,

I have a usercontrol in which there is SciChartSurface and Modifiers and this UserControl(Name = UCSciChart) have its own ViewModel(Name = UCSciChartViewModel). Now I have Another User Control(Name = TimeChartView) in which I placed UCSciChart usercontrol 1 for single mode and 16 for multiple mode. TimeChartView has its own view model (TimeChartViewModel). Now if click on series, the style applies, but if i click outside it does not goes to old style, it is in single mode. If i click on multiple mode, then there is multiple user control and all have their own view model. But in multiple mode, if i click on series no style is applied.

I am posting my code here:

UCSciChart.xaml

<s:SciChartSurface.ChartModifier>


<s:SeriesSelectionModifier.SelectedSeriesStyle>

</s:SeriesSelectionModifier.SelectedSeriesStyle>

</s:SciChartSurface.ChartModifier>

TimeChartView.xaml

<UniformGrid.ContextMenu>

</UniformGrid.ContextMenu>
