C# ActiveX Control - Events Error

Hello,
I need to design a full funcionaly ActiveX Data Grid.
I created an C# project:

Code:

---

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;

using System.Runtime.InteropServices;
using System.Reflection;
using Microsoft.Win32;

namespace ActiveXGrid
{
    [Guid("2DC138F0-1CB1-4F9A-ACC4-C3A1F708C495")]   
    public interface ItabelenForm //: ITreeViewEvents_Event
    {
        void Add(params object[] values);
        void AddEmptyLine();
        void AddEmptyColumn();
        string Get(int row, int cell);
    }

    [Guid("A798EE8C-9EB0-40F9-A075-506FDBB149E8")]
    [TypeLibType(4224)]
    [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
    public interface tabelenFormEvents
    {
        [DispId(1)]
        void Click();
    }

    [ProgId("tabelenFormTEST")]
    [ClassInterface(ClassInterfaceType.None)]
    [ComSourceInterfaces(typeof(tabelenFormEvents))]
    public partial class tabelenForm : UserControl, ItabelenForm
    {
        public tabelenForm()
        {
            InitializeComponent();
            base.Click += new EventHandler(CSActiveXCtrl_Click);
        }

        public void Add(params object[] values)
        {
            tabele.Rows.Add(values);
        }

        public void AddEmptyLine()
        {
            tabele.Rows.Add();
        }
        public void AddEmptyColumn()
        {
            tabele.Columns.Add("testCol", "TCol");
        }
        public string Get(int row, int cell)
        {
            return tabele.Rows[row].Cells[cell].Value.ToString();
        }

        #region register
        ///        <summary>
        ///        Register the class as a        control        and        set        it's CodeBase entry
        ///        </summary>
        ///        <param name="key">The registry key of the control</param>
        [ComRegisterFunction()]
        public static void RegisterClass(string key)
        {
            // Strip off HKEY_CLASSES_ROOT\ from the passed key as I don't need it
            StringBuilder sb = new StringBuilder(key);
            sb.Replace(@"HKEY_CLASSES_ROOT\", "");

            // Open the CLSID\{guid} key for write access
            RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);

            // And create        the        'Control' key -        this allows        it to show up in
            // the ActiveX control container
            RegistryKey ctrl = k.CreateSubKey("Control");
            ctrl.Close();

            // Next create the CodeBase entry        - needed if        not        string named and GACced.
            RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
            inprocServer32.SetValue("CodeBase", Assembly.GetExecutingAssembly().CodeBase);
            inprocServer32.Close();

            // Finally close the main        key
            k.Close();
        }

        ///        <summary>
        ///        Called to unregister the control
        ///        </summary>
        ///        <param name="key">Tke registry key</param>
        [ComUnregisterFunction()]
        public static void UnregisterClass(string key)
        {
            StringBuilder sb = new StringBuilder(key);
            sb.Replace(@"HKEY_CLASSES_ROOT\", "");

            // Open        HKCR\CLSID\{guid} for write        access
            RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);

            // Delete the 'Control'        key, but don't throw an        exception if it        does not exist
            k.DeleteSubKey("Control", false);

            // Next        open up        InprocServer32
            RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);

            // And delete the CodeBase key,        again not throwing if missing
            k.DeleteSubKey("CodeBase", false);

            // Finally close the main key
            k.Close();
        }
        #endregion

        [ComVisible(false)]
        public delegate void ClickEventHandler();
        public new event ClickEventHandler Click = null;

        void CSActiveXCtrl_Click(object sender, EventArgs e)
        {
            if (null != Click) Click();    // Raise the new Click event.
        }

    }
}

The "tabele" is an:

Code:

---

private System.Windows.Forms.DataGridView tabele;

---

The ActiveX Control is registering properly, etc.
I created a new C# Windows Form project (container for the ActiveX control).
I puted the ActiveX control without problems on the form.
The interface for the methods is working properly, but I have a problem with getting the events:

Code:

---

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            tabelEvent.Click += new ActiveXGrid.tabelenForm.ClickEventHandler(onActivexClicked);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            tabelenForm1.Add("test");
        }

        private void button2_Click(object sender, EventArgs e)
        {
            tabelenForm1.AddEmptyColumn();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            tabelenForm1.AddEmptyLine();         
        }

        public void onActivexClicked()
        {
            button1.Text = "OK";
        }
    }
}

---

I have declared it like this:

Code:

---

private ActiveXGrid.tabelenFormEvents tabelEvent;
private ActiveXGrid.tabelenForm tabelenForm1;

---

On the line:

Code:

---

tabelEvent.Click += new ActiveXGrid.tabelenForm.ClickEventHandler(onActivexClicked);

---

I getting an error:
"Click" ist "Methodengruppe", daher ist die Zuordnung nicht möglich.
I have an German Visual and it means tha "Click" is a "Method group", so the assignment is not possible.
Please help me, I'm working on this control a whole week.
The control is based on the article:

Thank You very much good people ;)
