DataGridView 中的 DataGridViewCheckBoxColumn 的值得改变 需要实现的功能

在CheckBox改变值得时候，执行需要的业务。
 
 summary
     我的做法是，将焦点转移出去，触发CellValueChanged事件
     summary
    public partial class Form1  Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            CreateData();
        }

         summary
         绑定数据
         summary
        private void CreateData()
        {
            DataTable dtSource = new DataTable();
            dtSource.Columns.Add(isNeed,typeof(bool));
            dtSource.Columns.Add(no, typeof(string));
            dtSource.Columns.Add(number, typeof(string));
            dtSource.Columns.Add(odds, typeof(string));
            for (int i = 0; i  14; i++)
            {
                DataRow dr = dtSource.NewRow();
                dr[0] = (i % 2 == 0);
                dr[1] = i.ToString().PadLeft(2, '0');
                dr[2] = i.ToString() + i.ToString() + i.ToString();
                dr[3] = i.ToString() + i.ToString() + i.ToString() + i.ToString();
                dtSource.Rows.Add(dr);
            }

            dgTest.DataSource = dtSource;
        }

         summary
         在单元格的值更改时发生。
         summary
         param name=senderparam
         param name=eparam
         remarks注意：此事件在 .NET Framework 2.0 版中是新增的。remarks
        private void dgTest_CellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (dgTest.DataSource == null)
            {
                return;
            }
            if (this.dgTest.Columns[this.dgTest.CurrentCell.ColumnIndex].Name == colIsNeed)
            {
                DataGridViewCheckBoxCell oCell = this.dgTest.CurrentCell as DataGridViewCheckBoxCell;
                if ((bool)oCell.Value)
                {
                    dgTest[colNumber,e.RowIndex].Value = e.RowIndex.ToString() + 9999;
                }
                else
                {
                    dgTest[colNumber, e.RowIndex].Value = ;
                }
            }
        }

         summary
         在单元格中的内容被单击时发生。
         summary
         param name=senderparam
         param name=eparam
         remarks注意：此事件在 .NET Framework 2.0 版中是新增的。 remarks
        private void dgTest_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            if (this.dgTest.Columns[this.dgTest.CurrentCell.ColumnIndex].Name == colIsNeed)
            {
                SendKeys.SendWait({tab});
                SendKeys.SendWait(+{tab});
            }
        }
    }


更好的方法CellMouseUp
private void dgTest_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
        {
            if (dgTest.DataSource == null)
            {
                return;
            }
            if (this.dgTest.Columns[this.dgTest.CurrentCell.ColumnIndex].Name == colIsNeed)
            {
                DataGridViewCheckBoxCell oCell = this.dgTest.CurrentCell as DataGridViewCheckBoxCell;
                if ((bool)oCell.FormattedValue)
                {
                    dgTest[colNumber, e.RowIndex].Value = e.RowIndex.ToString() + 9999;
                }
                else
                {
                    dgTest[colNumber, e.RowIndex].Value = ;
                }
                dgTest.CommitEdit(DataGridViewDataErrorContexts.Formatting);
            }
        }

  KeyUp
private void dgTest_KeyUp(object sender, KeyEventArgs e)
        {
            if (this.dgTest.Columns[this.dgTest.CurrentCell.ColumnIndex].Name == colIsNeed)
            {
                if (e.KeyCode == Keys.Space)
                {
                    dgTest.CommitEdit(DataGridViewDataErrorContexts.CurrentCellChange);
                    if (!(bool)this.dgTest.CurrentCell.FormattedValue)
                    {
                        其他处理①
                        dgTest[colNumber, this.dgTest.CurrentCell.RowIndex].Value = this.dgTest.CurrentCell.RowIndex.ToString() + 9999;
                    }
                    else
                    {
                        其他处理②
                        dgTest[colNumber, this.dgTest.CurrentCell.RowIndex].Value = ;                        
                    }
                }
            }
        }
