c# - Xceed PropertyGrid 中的类别排序

Question

我正在使用Xceed 的PropertyGrid 来显示一些元素的特性。元素有不同的类别，例如:常规、高级、其他、特殊。在这里，我发现 Xceed 的属性网格按字母顺序对类别和属性进行排序。我能够使用 [PropertyOrder(n)] 对类别内的属性进行排序。我也想对类别进行排序，所以我尝试使用 CategoryOrder 之类的 [CategoryOrder("General", 0)] 但它显示以下错误:

Error 2 Attribute 'CategoryOrder' is not valid on this declaration type. It is only valid on 'class' declarations.

我是不是用错了？下面提供的代码只是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

这是一个关于如何使用它的示例:

[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; }
}
