    其中，按钮绑定的是x:Name="ShowAddGood"

    对应的ViewModel有ShowAddGood这个事件

    其中添加按钮绑定的还是 x:Name="AddGood"

    对应的viewModel有"AddGood"

      public class GoodstDataViewModel : IParcelInputModel
  {
    public GoodstDataViewModel(IEventAggregator eventAggregator)
    {
      DisplayName = "入库物品";
      this.eventAggregator = eventAggregator;
    }
    private readonly IEventAggregator eventAggregator;
    public BindableCollection<AddGoodsViewModel> AddGoods { get; } = new BindableCollection<AddGoodsViewModel>();
    public AddGoodsViewModel SelectedAddGoods { get; set; }
    

    #region  绑定
    public void AddGood()
    {
      //if (AddGoods == null) return;

      //eventAggregator.PublishOnUIThread(new ActiveScreenInShellMsg(SelectedAddGoods));

      ////if (SelectedGoods == null) return;
      var screen = IoC.Get<AddGoodsViewModel>();
      //var screen = new GoodstDataViewModel
      //{
      //  Goods = SelectedGoods
      //};
      eventAggregator.PublishOnUIThread(new ActiveScreenInShellMsg(screen));
    }
    #endregion
    View Code

    对应的子窗体的viewmodel

    public class AddGoodsViewModel : Screen
  {
    public AddGoodsViewModel(IEventAggregator eventAggregator)
    {
      this.eventAggregator = eventAggregator;
    }
    private readonly IEventAggregator eventAggregator;
  }
