If you want to generate programmatically click on DataGridViewButtonCell instance, you can use DataGridViewCell.AccessibilityObject property and call DoDefaultAction method.

Something like this (sorry for C#, I'm sure you can translate it to VB):

DataGridViewButtonCell otherCell = ...;
otherCell.AccessibilityObject.DoDefaultAction();

Test:

using System;
using System.Linq;
using System.Windows.Forms;

namespace Samples
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            var form = new Form();
            var grid = new DataGridView { Dock = DockStyle.Fill, Parent = form, AutoGenerateColumns = false };
            var col0 = new DataGridViewTextBoxColumn { Name = "Col0", HeaderText = "Col0", DataPropertyName = "Col0" };
            var col1 = new DataGridViewButtonColumn { Name = "Col1", HeaderText = "Col1", DataPropertyName = "Col1" };
            grid.Columns.AddRange(new DataGridViewColumn[] { col0, col1 });
            grid.CellContentClick += (sender, e) =>
            {
                MessageBox.Show("Clicked Cell[" + e.RowIndex + "," + e.ColumnIndex + "]");
            };
            grid.DataSource = Enumerable.Range(0, 10).Select(n => new { Col0 = "Cell[" + n + ",0]", Col1 = "Cell[" + n + ",1]" }).ToList();
            var button = new Button { Dock = DockStyle.Bottom, Parent = form, Text = "Click" };
            button.Click += (sender, e) =>
            {
                var cell = grid.CurrentRow.Cells[col1.Index];
                cell.AccessibilityObject.DoDefaultAction();
            };
            Application.Run(form);
        }
    }
}
