Hello, I use custom events all the time but with the following piece of code I am not sure what is wrong. I am not able to Add an event handler to an instance of this class.

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

namespace CustomNotepad2
{
    public partial class frmGoTo : Form
    {
        public frmEditor FormEditor = new frmEditor();
        public delegate void GoToEventHandler(object sender, GoToEventArgs e);
        public GoToEventHandler GoToEvent;
        public frmGoTo()
        {
            InitializeComponent();
        }

        private void btnGoTo_Click(object sender, EventArgs e)
        {
            OnGoTo(new GoToEventArgs(int.Parse(txtLineNumber.Text.Trim())));
        }

        private void btnCancel_Click(object sender, EventArgs e)
        {
            this.Close();
        }
        protected virtual void OnGoTo(GoToEventArgs e)
        {
            if (GoToEvent != null)
            {
                GoToEvent(this, e);
            }
        }
    }
   
    public class GoToEventArgs : EventArgs
    {
        int _line = 0;
        public GoToEventArgs(int line)
        {
            _line = line;
        }
        public int GoToLine
        {
            get
            {
                return _line;
            }
        }
    }
}
