Question

Answer 1

Another solution is to use Trigger Style:

In the model class:

public class ModelClass: INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private void NotifyPropertyChanged(string name)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
    }

    private bool _vis;
    public bool vis
    {
        get => _vis;
        set
        {
            _vis = value;
            NotifyPropertyChanged("vis");
        }
    }
}

Don't forget to bind DataContext with your model !

DataContext = new ModelClass();
