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 > -) && (e.ColumnIndex > -))
             {
                 string dataPropertyName = this.dgvReaschResult.Columns[e.ColumnIndex].DataPropertyName;
                 switch (dataPropertyName)
