ObservableColletion and ObservableObject

[candinho1987]

Hello everyone, i'n trying to use observable object and collection, but the ui doesn't get updated,

public partial class MedidasViewModel : ObservableObject
{
    public ObservableCollection<Medida> Medidas { get; set; }    

    public MedidasViewModel()
    {
        Medidas = new ObservableCollection<Medida>();
        
        using (AppDbContext context = new AppDbContext())
        {
            
            List<Medida> lista = context.Medida.ToList();


            foreach (var item in lista)
            {
                Medidas.Add(item);
                
            }
        }
    }

    [ObservableProperty]
    [NotifyPropertyChangedFor(nameof(DescricaoNovaMedida))]
    string descricaoNova;

    [ObservableProperty]
    [NotifyPropertyChangedFor(nameof(SiglaNovaMedida))]
    string siglaNova;

    [ObservableProperty]
    [NotifyPropertyChangedFor(nameof(ConvervorNovaMedida))]
    decimal conversorNova;
    public string DescricaoNovaMedida => descricaoNova;
    public string SiglaNovaMedida => siglaNova;
    public double ConvervorNovaMedida => Convert.ToDouble(conversorNova);

    [RelayCommand]
    void SalvarNovaMedidaVM()
    {

        Medida medida = new Medida();
        medida.Descricao = DescricaoNovaMedida;
        medida.Sigla = SiglaNovaMedida;
        medida.Conversor = Convert.ToDecimal(ConvervorNovaMedida);
        using (var context = new AppDbContext())
        {
            context.Medida.Add(medida);
            context.SaveChanges();
            int idNovaMedida = medida.Id;
            Medidas.Add(medida);
        }
    }
}

When i execute Medidas.Add(medida); the collection get the new Medida record, but the ui is not updated with the newly added item, and if i close the page and open again, then the new medida show up on the picker/datagrid.
I realy don't know what i'n doing wrong

I would suggest making Medidas get only and double-check UI bindings. Nothing seems out of place for this code snippet.

I suggest pasting UI code here.
