dgr.ReadOnly = true;

for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)

dgr.Cells[3].Value = Convert.ToInt32(dgr.Cells[3].Value) + Convert.ToInt32(dataGridView1.Rows[i].Cells[3].Value);

int aa = Convert.ToInt32(dgr.Cells[2].Value);
dgr.Cells[1].Value = Convert.ToInt32(ss - aa);
}
合计这行怎么一点击就没了? 上面代码写的form_load事件里!!怎么改才能保证合计这行不消失~!
把 DataGridViewRow dgr =dataGridView1.Rows[dataGridView1.Rows.Count-1];改成 DataGridViewRow dgr =dataGridView1.Rows[dataGridView1.Rows.Count-2];但把最后条数据给覆盖了!!请问解决方法!!谢谢大虾!!
