the model implements inotifypropertychanged interface. if there change in of properties view getting updated.

but if new row gets added database view not getting updated. in case third party webservice writes data database. whenever data gets added/deleted want update ui.

how can achieve this?

listview.itemssource = viewmodel.employeelist

you can write own class raises , event every time , object added , listen it.
