How can I override a property in a RealmObject using realm database?

Question

I want to override the following property using Realm so I can trigger a RaisePropertyChanged for another property:

public int Reps { get; set; }

This doesn't work, because it does not get picked up by Realm as a column in the database:

private int _reps;
public int Reps
{
    get => _reps;
    set
    {
        RaisePropertyChanged("Reps");
        RaisePropertyChanged("RepsInfo");
        _reps = value;
    }
}
public int Reps { get; set; }

For what it's worth RepsInfo looks like this:

public string SetRepInfo { get => $"{Sets}x{Reps}"; }

The reason I want to do a RaisePropertyChanged("RepsInfo") is because all places where I'm using this object does not get an updated SetRepInfo when the Reps is updated.

You should instead override the OnPropertyChanged method. Adapting the example from the docs you need something like:

protected override void OnPropertyChanged(string propertyName)
{
    if (propertyName == nameof(Reps))
    {
        RaisePropertyChanged(nameof(SetRepInfo));
    }
}
