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
