Select PointMarkers on Binding Code

Hi,

I begin with Scichart, I am coding with binding program and I need to make Selection Point Markers. I can see the point Markers but when I activate the SelectedPointMarker then it doesn’t work. I want to ask how to adapt the exemple with a binding program, what to write in the “.cs”. I am sending you the wpf code and the interface. Can you help me please?

Thank you verry much.
