编辑datagridview单元格

Posted 2020-08-16 吃饭睡觉敲代码

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。

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

View Code

 1 public PlanVindicateForm()
 2         {
 3             InitializeComponent();
 4             dgvReaschResult.Controls.Add(dtp);//在窗体的构造函数里将datetimepicker控件加入
 5             this.dgvReaschResult.Controls.Add(this.sellstyle);//combox控件
 6             this.sellstyle.Visible = false;//设置是否显示
 7             this.dtp.Visible = false;
 8             this.dtp.Format = DateTimePickerFormat.Custom;//设置显示格式
 9             this.dtp.CustomFormat = "HH:mm";
10             this.dtp.KeyDown += new KeyEventHandler(dtp_KeyDown);//注册控件用到的事件
11             this.sellstyle.cbTypeBox.SelectedIndexChanged += new EventHandler(cbTypeBox_SelectedIndexChanged);
12         }
