DateGridView首列排序

第一步：初始化的时候，新建固定行数的表格

        private void Form1_Load(object sender, EventArgs e)
        {
    
            int index = 0;


            for (int i=1;i<=12;i++)
            {
    
                index = this.dataGridView1.Rows.Add();
             
                this.dataGridView1.Rows[index].Cells[0].Value = i;
                this.dataGridView1.Rows[index].Cells[1].Value = 1111111111;
            }
            
        }

第二步：新增事件，在删除行的时候执行下面的代码

        private void dataGridView1_RowsRemoved(object sender, DataGridViewRowsRemovedEventArgs e)
        {
    
            int index = this.dataGridView1.Rows.Add();
            for (int i = 1; i <= 12; i++)
            {
    
                this.dataGridView1.Rows[i-1].Cells[0].Value = i;
            }
            MessageBox.Show("would you delete this row ?","Attention",MessageBoxButtons.YesNoCancel);
        }
