c# datagridview在编辑时触发事件，获取输入值

datagridview在设计时，需要在单元格编辑时触发相关事件获取数据

private void dgv_CurrentCellDirtyStateChanged(object sender, EventArgs e)
        {
            if (dgv.IsCurrentCellDirty)
            {
                dgv.CurrentCellDirtyStateChanged -= dgv_CurrentCellDirtyStateChanged;
                dgv.CommitEdit(DataGridViewDataErrorContexts.Commit);
                dgv.CurrentCellDirtyStateChanged += dgv_CurrentCellDirtyStateChanged;
                int c = dgv.CurrentCellAddress.X;
                int r = dgv.CurrentCellAddress.Y;

                label1.Text = dgv.CurrentCell.Value.ToString();
                

                
                
            }
        }
