删除项目GridView Windows 8地铁

我试图从GridView控件中删除项目。当我点击删除时，GridView无法更新删除项目GridView Windows 8地铁

我已经绑定了GridView和可观察集合中的订单列表。这里是我的订单类：

public class Order : INotifyPropertyChanged 
{ 
    public Order() { } 
    private int _id; 
    [PrimaryKey, AutoIncrement] 
    public int Id 
    { 
     get { return _id; } 
     set 
     { 

      this._id = value; 
      Notify("ID"); 
     } 
    } 
    public int RestaurantID { get; set;} 
    public DateTime Date { get; set; } 
    public string Note { get; set; } 
    public decimal TotalPrice { get; set; } 
    [Ignore] 
    public List<OrderDetail> OrderDetails { get; set; } 

    #region INotifyPropertyChanged Members 

    [Ignore] 
    public event PropertyChangedEventHandler PropertyChanged; 

    [Ignore] 
    protected void Notify(string propName) 
    { 
     if (this.PropertyChanged != null) 
     { 
      PropertyChanged(this, new PropertyChangedEventArgs(propName)); 
     } 
    } 
    #endregion 
}

这里是我的数据绑定代码：

ObservableCollection<Order> orderCollection = new ObservableCollection<Order>(); 
      foreach (Order ord in orders) 
      { 
       orderCollection.Add(ord); 
      } 

      this.DefaultViewModel["Items"] = orderCollection;

我的删除按钮在GridView的DataTemplate中存在。这是我的删除代码：

private void btnDelete_Click_1(object sender, RoutedEventArgs e) 
    { 
     Button btnDelete = (Button)sender; 
     Order order = btnDelete.DataContext as Order; 
     repository.DeleteOrder(order.Id); 
    }

它看起来像代码只是从存储库中删除项目。您还需要将其从ObservableCollection中删除。尝试在repository.DeleteOrder(order.Id)下加入：

orderCollection.Remove(order);
