Hi there,

Thanks for your question. I’m not sure why this doesn’t work. However, I have a suggestion for you to try. I think it would be better if you subscribe SciChartSurface instead to listen to KeyDown and inside the event handler just go through the Annotations collection and remove all annotations which are selected.

If this isn’t suitable for you, you can try handling PreviewKeyDown instead.

Best regards,
