我已经试过了，但效果不太好

• 对于按钮11-15，只有"<"出现，因为一旦点击，就没有其他按钮了。
• 按钮6-10显示，<和›均可见
• 查看按钮1-5：只有一个›按钮

例如，如果有15个按钮，屏幕只能显示5个按钮"<"和"»"按钮出现，当点击时，向左或向右滚动它应该跳转视图。例如，按一次它应该显示按钮6-10，然后再次按它显示按钮11-15需要2次点击才能看到整个15个按钮

partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        // need to disable AutoScroll, otherwise disabling the horizontal scrollbar doesn't work
        Panel.AutoScroll = false;

        // disable horizontal scrollbar
        Panel.HorizontalScroll.Enabled = false;
    }

    public int scrollValue = 0;

    public int ScrollValue
    {
        get
        {
            return scrollValue;
        }
        set
        {
            scrollValue = value;

            if (scrollValue < Panel.HorizontalScroll.Minimum)
            {
                scrollValue = Panel.HorizontalScroll.Minimum;
            }

            if (scrollValue > Panel.HorizontalScroll.Maximum)
            {
                scrollValue = Panel.HorizontalScroll.Maximum;
            }

            Panel.HorizontalScroll.Value = scrollValue;
            Panel.PerformLayout();
        }
    }

    private void btnleft_Click(object sender, EventArgs e)
    {
        ScrollValue -= Panel.HorizontalScroll.LargeChange;
    }

    private void btnright_Click(object sender, EventArgs e)
    {
