Data Binding

Interfaces that inherit from INotifyPropertyChanged or INotifyPropertyChanging will invoke the PropertyChangedEventHandler and PropertyChangingEventHandler events respectively when property values are changing / changed. Here is a simple example of how it works:

[Generate]
public interface IHaveAnId : INotifyPropertyChanged, INotifyPropertyChanging
{
    Guid Id { get; set; }
}

The generated code will look like:

public class HaveAnIdModel : IHaveAnId
{
    public System.Guid Id
    {
        get
        {
            return _Id;
        }
        set
        {
            PropertyChanging?.Invoke(this, new System.ComponentModel.PropertyChangingEventArgs("Id"));
            _Id = value;
            PropertyChanged?.Invoke(this, new System.ComponentModel.PropertyChangedEventArgs("Id"));
        }
    }
    private System.Guid _Id;
        
    public event System.ComponentModel.PropertyChangedEventHandler? PropertyChanged;
    public event System.ComponentModel.PropertyChangingEventHandler? PropertyChanging;
        
    public SupportNotifyPropertyChangingModel()
    {
    }
        
}
