Use following code as an example, so you know the basic idea of how to trace if an item in your ItemSource had been changed (here only compared to the initial value only).

List<myItem> Items=new List<myItem>(); //your ItemSource



    class myItem:ObservableObject //an class implement INotifyPropertyChanged interface
    {
        string _inititemName;
        string _itemName;
        bool itemChanged; //here is your indicator

        myItem(string name)
        {
            _inititemName=itemName=name;
        }

        public string itemName
        {   
            get{return _itemName;}
            set
            {  
                _itemName=vlaue; 
                if (_itemName!=_inititemName) 
                   itemChanged=true; 
                else 
                   itemChanged=false;
                RaisePropertyChanged("itemName"); //or whatever the name of the method is that invoke OnPropertyChanged
            }
        }
    }
