Automatically Adding DataGridView Columns

Question

I have a DataGridView populated with product information. There are only 50 columns in a datagridview, but users do not always need all the columns, I want to help them choose which columns to show and which ones not to show.

One solution that I would like to program is that when the user right-clicks on the columns, they can choose from the list that appears and choose which columns to show and which not to do. Like the image below.

How can i do this. I would really appreciate any help.

namespace WindowsFormsApplication4
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            BindingList<User> users = new BindingList<User>{
                  new User{Name = "John", Address="Home Street", Title="Mr."},
                  new User{Name = "Sally", Address="Home Street", Title="Mrs."}
            };

            contextMenuStrip1.AutoClose = true;       
            contextMenuStrip1.Closing += new ToolStripDropDownClosingEventHandler(contextMenuStrip1_Closing);

            dataGridView1.DataSource = users;

            dataGridView1.DataBindingComplete += new DataGridViewBindingCompleteEventHandler(dataGridView1_DataBindingComplete);
        }

        void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
        {

            foreach (DataGridViewColumn gridViewColumn in this.dataGridView1.Columns)
            {
                ToolStripMenuItem item = new ToolStripMenuItem();
                item.Name = gridViewColumn.Name;
                item.Text = gridViewColumn.Name;
                item.Checked = true;
                item.CheckOnClick = true;
                item.CheckedChanged += new EventHandler(item_CheckedChanged);
                contextMenuStrip1.Items.Add(item);
            }

            foreach (DataGridViewColumn gridViewColumn in this.dataGridView1.Columns)
            {
                gridViewColumn.HeaderCell.ContextMenuStrip = contextMenuStrip1;
            }

        }

        void item_CheckedChanged(object sender, EventArgs e)
        {
            ToolStripMenuItem item = sender as ToolStripMenuItem;

            if (item != null)
            {
                dataGridView1.Columns[item.Name].Visible = item.Checked;
            }
        }

        void contextMenuStrip1_Closing(object sender, ToolStripDropDownClosingEventArgs e)
        {
            if (e.CloseReason == ToolStripDropDownCloseReason.ItemClicked)
            {
                e.Cancel = true;
            }
        }
    }

    public class User
    {
        public string Name { get; set; }
        public string Address { get; set; }
        public string Title { get; set; }
    }

}
