参考代码：

private void Form1_Load(object sender, EventArgs e)
        {
            this.dataGridView1.Columns.Add("a", "a");
            this.dataGridView1.Columns.Add("b", "b");
            this.dataGridView1.Columns.Add("c", "c");

            for (int i = 0; i < 3; i++)
                this.dataGridView1.Rows.Add();

            for (int i = 0; i < 3; i++) { Button[] btn = new Button[2];
                btn[0] = new Button();
                btn[0].Text = "one";
                btn[1] = new Button();
                btn[1].Text = "two";
                this.dataGridView1.Controls.Add(btn[0]);
                this.dataGridView1.Controls.Add(btn[1]);
                Rectangle rect = this.dataGridView1.GetCellDisplayRectangle(2, i, false);
                btn[0].Size = btn[1].Size = new Size(rect.Width / 2, rect.Height);
                btn[0].Location = new Point(rect.Left, rect.Top);
                btn[1].Location = new Point(rect.Left + btn[0].Width, rect.Top);
                btn[0].Click += new EventHandler(CustomBtn_Click);
                btn[1].Click += new EventHandler(CustomBtn_Click);
            }
        }
        void CustomBtn_Click(object sender, EventArgs e)
        {
            MessageBox.Show((sender as Button).Text);
        }
 
在有滚动条时，在下面的两个事件中重定位一下Button的位置:
        //  滚动DataGridView时调整Button位置
        private void DataGridView_Scroll(object sender, ScrollEventArgs e)
        {
        }
        //  改变DataGridView列宽时调整Button位置
        private void DataGridView_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
        {
        }
