The implementation is as follows: 1. xml 2. CS medium Define ObservableCollection<Model> memberData = new ObservableCollection<Model>(); Model is defined as follows: public class Model : INotifyPropertyChanged { protected int span> id; protected string span> name; protected bool span> online; protected bool span> registered; public int span> ID { get => id; set => id = value; } public string span> Name { get => name; set => name = value; } public bool span> IsOnline { get => online ; set { if (online != value) { online = value; OnPropertyChanged(“IsOnline “); } } }…
