其中，按钮绑定的是x:Name="ShowAddGood"

对应的ViewModel有ShowAddGood这个事件

这个ShowAddGood事件是

 public BindableCollection<DataMaintenanceGood> Goods { get; } = new BindableCollection<DataMaintenanceGood>();
    public BindableCollection<DataMaintenanceType> Types { get; } = new BindableCollection<DataMaintenanceType>();

    public void ShowAddGood()
    {
      var screen = IoC.Get<AddGoodViewModel>();
      //windowManager.ShowDialog(screen);
      if (windowManager.ShowDialog(screen)==true)
      {
        Goods.Add(screen.SavedGood);
      }
    }

      if (windowManager.ShowDialog(screen)==true)
