参考代码：
1 private void Form1_Load(object sender, EventArgs e) 2 { 3 this.dataGridView1.Columns.Add("a", "a"); 4 this.dataGridView1.Columns.Add("b", "b"); 5 this.dataGridView1.Columns.Add("c", "c"); 6 7 for (int i = 0; i < 3; i++) 8 this.dataGridView1.Rows.Add(); 9 10 for (int i = 0; i < 3; i++) { Button[] btn = new Button[2]; 11 btn[0] = new Button(); 12 btn[0].Text = "one"; 13 btn[1] = new Button(); 14 btn[1].Text = "two"; 15 this.dataGridView1.Controls.Add(btn[0]); 16 this.dataGridView1.Controls.Add(btn[1]); 17 Rectangle rect = this.dataGridView1.GetCellDisplayRectangle(2, i, false); 18 btn[0].Size = btn[1].Size = new Size(rect.Width / 2, rect.Height); 19 btn[0].Location = new Point(rect.Left, rect.Top); 20 btn[1].Location = new Point(rect.Left + btn[0].Width, rect.Top); 21 btn[0].Click += new EventHandler(CustomBtn_Click); 22 btn[1].Click += new EventHandler(CustomBtn_Click); 23 } 24 } 25 void CustomBtn_Click(object sender, EventArgs e) 26 { 27 MessageBox.Show((sender as Button).Text); 28 } 29 30 在有滚动条时，在下面的两个事件中重定位一下Button的位置: 31 // 滚动DataGridView时调整Button位置 32 private void DataGridView_Scroll(object sender, ScrollEventArgs e) 33 { 34 } 35 // 改变DataGridView列宽时调整Button位置 36 private void DataGridView_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e) 37 { 38 }
