C# DataGridView中单元格Cell改变事件

datagridview控件中的各种事件都无法直接响应cell中内容的变化，包括keypress等事件，可以采用下面方法

private void datagridviewbarcode_editingcontrolshowing(object sender, datagridvieweditingcontrolshowingeventargs e)
        {
            if (e.control.gettype().equals(typeof(datagridviewtextboxeditingcontrol)))
            {
                e.cellstyle.backcolor = color.fromname("window");
                datagridviewtextboxeditingcontrol textcontrol = e.control as datagridviewtextboxeditingcontrol;
                textcontrol.textchanged += new eventhandler(textcontrol_textchanged);
            }
        }

private void textcontrol_textchanged(object sender, eventargs e)
        {
            this.label1.text = ((textbox)sender).text;
        }

 注：此方法无法响应cell中的回车键
