Xceed PropertyGrid中的类别订购

Question

我正在使用 Xceed的PropertyGrid 来显示某些元素的特征。元素有不同的类别，如：General，Advanced，Others，Special。在这里，我发现Xceed的propertygrid按字母顺序对类别和属性进行排序。我能够使用[PropertyOrder(n)]对类别中的属性进行排序。我还想对类别进行排序，我尝试使用CategoryOrder [CategoryOrder("General", 0)]，但它显示以下错误：

  

错误2属性'CategoryOrder'在此声明类型上无效。它仅对“类”声明有效。

我使用它错了吗？ 下面提供的代码只是一个展示我如何使用它的示例。

[Category("General")]
[CategoryOrder("General", 0)]
[DisplayName("XValue")]
[Description("Value of X-Coordinate")]
[ReadOnly(true)]
[PropertyOrder(1)]

[Category("Advanced")]
[CategoryOrder("Advanced", 1)]
[DisplayName("Collision")]
[Description("Collision")]
[ReadOnly(true)]
[PropertyOrder(1)]

[Category("Others")]
[CategoryOrder("Others", 3)]
[DisplayName("Traffic")]
[Description("Traffic at a point")]
[ReadOnly(true)]
[PropertyOrder(1)]

[Category("Special")]
[CategoryOrder("Special", 2)]
[DisplayName("Special cases")]
[Description("Contains the special cases and files")]
[PropertyOrder(1)]

Answer 1

以下是如何使用它的示例：

[CategoryOrder("General", 1)]
[CategoryOrder("Advanced", 2)]
[CategoryOrder("Other", 3)]
public class MyClass
{
    [Category("General")]
    public string Property1 { get; set; }
    [Category("Advanced")]
    public int Property2 { get; set; }
    [Category("Other")]
    public double Property3 { get; set; }
    [Category("General")]
    public string Property4 { get; set; }
    [Category("Advanced")]
    public int Property5 { get; set; }
    [Category("Other")]
    public double Property6 { get; set; }
}
