我正在尝试按照http://www.wpf-tutorial.com/listview-control/listview-grouping/向Master-Detail Collection(例如Order-OrderDetails)实现可折叠列表视图,但没有成功。我的目标是扩展Listview行(Order)并在用户行选择时显示所有OrderDetail条目。
public class Order
{
public int Id { get; set; }
public string OrderNumber{ get; set; }
public ObservableCollection<OrderDetail> OrderDetails { get; set; }
}
public class OrderDetail
{
public int Id { get; set; }
public string OrderNumber{ get; set; }
public string Description{ get; set; }
public double Cost{ get; set; }
public virtual Order Order { get; set; }
}
