如何在C＃中使用ExpandableObject装饰属性 [英] How to decorate property with ExpandableObject in C#

问题描述

我试图按照此处的说明在Xceed PropertyGrid中显示此类实例。：

    PG.SelectedObject = new Order()
        {
            ShipAddress = "Luisenstr. 48",
            ShipCountry = "Germany",
            ShipName = "Toms Spezialitaten",
            ShipPostalCode = "44087",
            chronology = new OrderChronology()
            {
                OrderDate = new DateTime(1996, 7, 5),
                ShippedDate = new DateTime(1996, 8, 16)
            }

        };

类似于我尝试做的行为的Xceed示例说 you必须使用ExpandableObject属性来装饰您的媒体资源。并显示以下内容：

The Xceed example for behavior analogous to what I am trying to do says you must decorate your property with the ExpandableObject attribute. and shows this:

       public class Person
    {
        [Category("Information")]
        [DisplayName("First Name")]
        [Description("This property uses a TextBox as the default editor.")]
        public string FirstName { get; set; }

        [Category("Conections")]
        [Description("This property is a complex property and has no default editor.")]


        [ExpandableObject]
        public Person Spouse { get; set; }
    }

当我尝试对班级做同样的事情（见下文）时导致编译器错误；它不喜欢 [ExpandableObject] ，并暗示我可能缺少using指令或程序集引用。是吗？

When I try to do the same with my class (see below) it causes a compiler error; it does not like [ExpandableObject] and hints that I may be missing a using directive or assembly reference. Am I?

 public class Order
  {

    public string ShipAddress { get; set; }
    public string ShipCountry { get; set; }
    public String ShipName { get; set; }
    public String ShipPostalCode { get; set; }

    [ExpandableObject]
    public OrderChronology chronology; 
  }

   public class OrderChronology
   {
      public DateTime OrderDate { get; set; }
      public DateTime ShippedDate { get; set; }
   }

推荐答案

您应添加程序集 Xceed.Wpf.Toolkit.dll ，然后应添加以下命名空间：

You should add assembly Xceed.Wpf.Toolkit.dll and after that you should add following namespace:

using Xceed.Wpf.Toolkit.PropertyGrid.Attributes;
