C#的trackBar控件问题

[taoye_11]

请问我在使用C#的trackBar时候，当使用方向键时，trackBar的标尺也跟着移动，我现在不想让标尺移动，请问怎么做，谢谢！！

this.KeyUp += (Object sd, KeyEventArgs arg) => { if (arg.KeyCode == Keys.Up) { trackBar1.Value = trackBar1.Value > 0 ? trackBar1.Value - 1 : 0; } else if (arg.KeyCode == Keys.Down) { trackBar1.Value = trackBar1.Value <100 ? trackBar1.Value + 1 : 100; }

        private void Form1_Load(object sender, EventArgs e)
        {
            trackBar1.Minimum = 0;
            trackBar1.Maximum = 100;

            this.KeyUp += (Object sd, KeyEventArgs arg) =>
            {
                if (arg.KeyCode == Keys.Up)
                {
                    trackBar1.Value = trackBar1.Value > 0 ? trackBar1.Value - 1 : 0;
                }
                else if (arg.KeyCode == Keys.Down)
                {
                    trackBar1.Value = trackBar1.Value <100 ? trackBar1.Value + 1 : 100;
                }
            };
        }
