DataGirdView 添加行與列的方法

分爲連接數據源和非數據源兩種

非連接數據源

              dataGridView1.ColumnCount = 3;
            dataGridView1.Columns[0].HeaderText = "ID號";
            dataGridView1.Columns[1].HeaderText = "時間";
            dataGridView1.Columns[2].HeaderText = "心跳值";

           

         DataGridViewRow row = new DataGridViewRow();
           
            //row.Cells["ID號"].Value = "1";
;
            row.CreateCells(dataGridView1);
            row.Cells[0].Value = "1";
            row.Cells[1].Value = "1";

            row.Cells[2].Value = "60";

            dataGirdView1.Rows.Insert(0,row);
            dataGridView1.Rows.Add(row);

連接數據源

  DataTable dt = new DataTable();
            dt.Columns.Add("a");
            dt.Columns.Add("b");
            DataRow dr = dt.NewRow();
          
            dr["a"] = "1";
            dr["b"] = "2";
            dt.Rows.Add(dr);
            dr = dt.NewRow();

            dataGridView1.DataSource = dt;
