Answer 1

You need to inherit 'BindableObject' and notify the view about the property changed inside the setter 'set {}' for the properties that you are binding in the view. I have modified your code below for Name property, you can change based on your requirements for other fields.

public class Part : BindableObject
{
    public int Id { get; set; }
    public string Brand { get; set; }
    public string BrandImage { get; set; }

    private string _Name;
    public string Name
    {
        get { return _Name; }
        set
        {
            _Name = value;
            OnPropertyChanged();
        }
    }
    public string Article { get; set; }
    public string Mfg { get; set; }
    public string Image { get; set; }
    public string Description { get; set; }
    public List<Offer> Offers { get; set; }
}

 public List<Offer> Offers { get; set; }
