    public bool IsComboBoxEnabled
    {
        get { return isComboBoxEnabled; }
        set
        {
            if (isComboBoxEnabled != value)
            {
                isComboBoxEnabled = value;
                OnPropertyChanged(nameof(IsComboBoxEnabled));
            }
        }
    }

    // Implement INotifyPropertyChanged interface
    // ...

    public ICommand ButtonCommand { get; }

    public ViewModel()
    {
        ButtonCommand = new RelayCommand(ButtonClick);
    }

    private void ButtonClick()
    {
        IsComboBoxEnabled = false;

    }
}
