C#如何在datagridview中动态增加button按钮行的代码

public Form1()
{
InitializeComponent();
this.Load += new EventHandler(Form1_Load);
}

List strSourec = new List { "1", "2" };

void Form1_Load(object sender, EventArgs e)
{
foreach (string item in strSourec)
{
DataGridViewButtonColumn Column1 = new DataGridViewButtonColumn();
Column1.HeaderText = item;
this.dataGridView1.Columns.Add(Column1);
}
DataGridViewRow dr = new DataGridViewRow();

for (int i = 0; i < strSourec.Count; i++)
{
DataGridViewButtonCell dgvbc = new DataGridViewButtonCell();
dgvbc.Value = strSourec[i];
dr.Cells.Add(dgvbc);
}
dataGridView1.Rows.Add(dr);

this.dataGridView1.CellMouseDown += new DataGridViewCellMouseEventHandler(dataGridView1_CellMouseDown);
}

void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
if (dataGridView1[e.ColumnIndex, e.RowIndex].Value == null) return;
MessageBox.Show(dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString());
}
