给groupBox添加滚动条

 public Form3()        {            InitializeComponent();            foreach (Control gbox in groupBox1.Controls)            {                if (gbox is VScrollBar) continue;                gbox.Tag = gbox.Location.Y;            }            panelControl1.VerticalScroll.Value = panelControl1.VerticalScroll.Maximum;           }

然后加入一个垂直滚动条控件,并添加如下事件:

 private void vScrollBar1_Scroll(object sender, ScrollEventArgs e)        {            foreach (Control gbox in groupBox1.Controls)            {                if (gbox is VScrollBar) continue;                gbox.Location = new Point(gbox.Location.X, (int)gbox.Tag - e.NewValue);            }        }

注意:给groupbox 的父panel 设置AutoScroll=true
