Visual Studio 2008 - Making properties editable in Properties Toolbar

Hi everybody!
I have a little problem with making properties editable under VS2008.
For example I've class:

using System;
using System.Collections.Generic;
using System.Text;

using System.Runtime.Serialization;
using System.Security.Permissions;

namespace ProjektBDApp.NowaWersja.Klasy
{
    public class ControlVector : ISerializable
    {
        int left;
        int top;
        int width;
        int height;

        #region Acessors
        public int Left
        {
            get { return left; }
            set { left = value; }
        }

        public int Top
        {
            get { return top; }
            set { top = value; }
        }

        public int Width
        {
            get { return width; }
            set { width = value; }
        }

        public int Height
        {
            get { return height; }
            set { height = value; }
        } 
        #endregion

        public ControlVector()
        {
            Top = Left = Width = Height = 0;
        }

        public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
        {
            info.AddValue("Left", Left);
            info.AddValue("Top", Top);
            info.AddValue("Width", Width);
            info.AddValue("Height", Height);
        }
        

        public ControlVector(SerializationInfo info, StreamingContext ctxt)
        {
            Left = info.GetInt32("Left");
            Top = info.GetInt32("Top");
            Width = info.GetInt32("Width");
            Height = info.GetInt32("Height");
        }
    }
}

And I want to make it member of my own control (exactly for component contaning many controls inside). But when I try to modificate it in VS designer (when I add my component to a form) I see only type name in Properties toolbox like this: "ProjektBDApp.NowaWersja.Klasy.ControlVector"
I want to see tree where I can modify localization.
