How to refresh component tree

Hi and thank you @Enchev for your fast answer. My problem is that each chid component must call the service to know if some modifications have occured. The service may present a boolean or anything else to tell if some new data are present but obviously, the component must call it to check new data arrival. Can you confirm that if I apply a StateHasChanged to a parent component, it will generate refresh to all its children ? @safournier

there are links at the bottom that may help.
