Hi;

I would like to delete selected annotation when “delete” key are pressed on it; like this :

(newAnnotation as AnnotationBase).KeyDown += (o, e) =>
{
this._chart.Annotations.Remove(newAnnotation);
};

I made this method when I create annotation on CreationModifier.AnnotationCreated event.
but is not work; the event are not handled.
Can you tell me how can I do this please

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,
Yuriy
