You don't need sortComparator input to sort the data you can sort your data direcly inside getServiceside drop down method like this.serviceCallDropdowns.sort((a,b)=>a.ServiceCall > b.ServiceCall) – Chellappan வ Jan 30 '20 at 09:05
it showing an error on sort function: "property 'sort' doesn't exist on Servicecalldropdown" and i set modal class for it "public servicecalldropdowns: Servicecalldropdown;' – ResolveError Jan 30 '20 at 09:31
