Answer 1

Create a viewmodel which can be set as the data context for the XAML

 public class WindowsViewModel
 {
    private ObservableCollection m_Rows;

    public ObservableCollection Rows
    {
        get { return m_Rows; }
        set { m_Rows = value; }
    }

    public WindowsViewModel()
    {
        Rows = new ObservableCollection();
        Rows.Add(new RowViewModel
            {
                ID = "42",
                Category = "cat",
                CharLimit = 32,
                Text = "Bonjour"
            });
    }
}

Implement the class RowViewModel in the below fashion:

 public class RowViewModel:INotifyPropertyChanged
    {
      public RowViewModel()
      {
      }
      private string m_ID;
      public string ID
      { 
            get
            {
                return m_ID;
            } 
            set 
            {
                m_ID = value;
                NotifyPropertyChanged("ID");
            }
      }
      public string Category
      { 
            get; 
            set; 
      }

      public int CharLimit
      { 
        get; 
        set; 
      }

      public string Text 
      { 
        get;
        set;
      }

    public event PropertyChangedEventHandler PropertyChanged;

    private void NotifyPropertyChanged(string Obj)
    {
        if (PropertyChanged != null)
        {
            this.PropertyChanged(this,new PropertyChangedEventArgs(Obj));
        }
    }
}

In the code behind of XAML, add the code:

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.DataContext = new WindowsViewModel();
        }
    }

Add the update source trigger property in the listview node:
