该方法是通过更改ShowDetail的状态来实现的隐藏属性

首先在引用里右键 管理NuGet程序包 查找extended wpf toolkit 并安装

然后在MainWindow.xaml添加引用 xmlns:extoolkit="http://schemas.xceed.com/wpf/xaml/toolkit" extoolkit为自命名

页面代码如下

<Window x:Class="Toolkitpropertygrid.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Toolkitpropertygrid"
        xmlns:extoolkit="http://schemas.xceed.com/wpf/xaml/toolkit"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <extoolkit:PropertyGrid Name="propertygrid1"></extoolkit:PropertyGrid>
    </Grid>
</Window>

然后在MainWindow.xaml.cs里面添加

[TypeConverter(typeof(A.PropertyConverter))]
    class A
    {
        [RefreshProperties(RefreshProperties.All)]
        public bool ShowDetail { get { return showDetail; } set { showDetail = value; } }
        public string Summary { get { return summary; } set { summary = value; } }
        public string Address1 { get { return address1; } set { address1 = value; } }
        public string Address2 { get { return address2; } set { address2 = value; } }

        private class PropertyConverter : ExpandableObjectConverter
        {
            public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes)
            {
                PropertyDescriptorCollection collection = TypeDescriptor.GetProperties(value, false);
                List<PropertyDescriptor> list = new List<PropertyDescriptor>();
                list.Add(collection["ShowDetail"]);

                if ((value as A).ShowDetail)
                {
                    list.Add(collection["Address1"]);
                    list.Add(collection["Address2"]);
                }
                else
                {
                    list.Add(collection["Summary"]);
                }
                return new PropertyDescriptorCollection(list.ToArray());
            }
        }

        private bool showDetail;
        private string summary, address1, address2;
    }

在MainWindow()里面添加

this.propertygrid1.SelectedObject = new A();

运行程序

当勾选 ShowDetail 时 会显示隐藏的属性 并隐藏当前显示的属性
