Winforms无法在设计时设置Property-Values

Question

Iam尝试基于DevExpress Grid创建自己的GridControl（v.14.2）。这看起来效果很好，但我的设置对象在Designer中不可编辑。

到目前为止，这是我的网格：

    [ToolboxItem(true)]
    [DXToolboxItem(true)]
    public class MyGrid : GridControl
    {
        private Settings _settings;

        public MyGrid()
        {
            _settings= new Settings();
        }

        [Category("My Category")]
        [Description("My Description")]
        [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
        public Settings Settings
        {
            get { return _settings; }
            set { _settings = value; }
        }
}

这是我的设置类：

    [EditorBrowsable(EditorBrowsableState.Always)]
    public class Einstellungen
    {
        [Category("My Category")]
        [Description("My Description")]
        public bool CanGroup { get; set; }

        [Category("My Category")]
        [Description("My Description")]
        public bool IsEditable { get; set; }
}

是否有任何遗失的属性？搜索msdn，但他们也只是推荐使用的属性......

在Designer中我只能看到： 设置| MyNamespace.Settings 但无法编辑bool属性。

也许这有效......

[TypeConverter(typeof(ExpandableObjectConverter))]
[EditorBrowsable(EditorBrowsableState.Always)]
public class Einstellungen
{
    [Category("My Category")]
    [Description("My Description")]
    [Browsable(true)]
    [EditorBrowsable(EditorBrowsableState.Advanced)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    public bool CanGroup { get; set; }

    [Category("My Category")]
    [Description("My Description")]
    [Browsable(true)]
    [EditorBrowsable(EditorBrowsableState.Advanced)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    public bool IsEditable { get; set; }
}
