编辑datagridview单元格

以这3种为例，最简单的是第三种，直接让单元格处于可编辑状态，当完成编辑后触发CellEndEdit事件，最后对输入的数据进行处理。

private DateTimePicker dtp = new DateTimePicker();
private ComBox sellstyle = new ComBox ();//设置全局变量

public PlanVindicateForm()
        {
            InitializeComponent();
            dgvReaschResult.Controls.Add(dtp);//在窗体的构造函数里将datetimepicker控件加入
            this.dgvReaschResult.Controls.Add(this.sellstyle);//combox控件
            this.sellstyle.Visible = false;//设置是否显示
            this.dtp.Visible = false;
            this.dtp.Format = DateTimePickerFormat.Custom;//设置显示格式
            this.dtp.CustomFormat = "HH:mm";
            this.dtp.KeyDown += new KeyEventHandler(dtp_KeyDown);//注册控件用到的事件
            this.sellstyle.cbTypeBox.SelectedIndexChanged += new EventHandler(cbTypeBox_SelectedIndexChanged);
        }

private void dgvReaschResult_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if ((e.RowIndex > -1) && (e.ColumnIndex > -1))
            {
                string dataPropertyName = this.dgvReaschResult.Columns[e.ColumnIndex].DataPropertyName;
                switch (dataPropertyName)
                {
                    case "CanSellSeatCount":

                        this.dgvReaschResult.BeginEdit(true);
                        this.Original = int.Parse(this.dgvReaschResult.Rows[this.dgvReaschResult.CurrentCell.RowIndex].Cells[e.ColumnIndex].Value.ToString());
                        return;

                        this.dtp.Value = DateTime.Parse(this.SelectSchedule.DrvTime);
                        this.dtp.Focus();
                        this.originaTime = this.dtp.Value;
