嗨专家，

我需要根据需要在Panel中自定义滚动条。所以我隐藏了Panel中的默认VerticalScroll并使用了System.Windows.Forms.VScrollBar。

嗨Ravindran，

Hi Ravindran,

如果您想使用面板中的vScrollbar，你必须在面板中放置一个控件并使其高于面板。

If you want to use the vScrollbar in panel, you have to put a control in the panel and make it higher than the panel.

然后代码：

        private void Form5_Load(object sender, EventArgs e)
        {
            vScrollBar1.Maximum = pictureBox1.Height - panel1.Height;
        }

        private void vScrollBar1_Scroll(object sender, ScrollEventArgs e)
        {
            pictureBox1.Top = -vScrollBar1.Value;
        }

问候，

Frankie
