给groupBox添加滚动条

时间:2021-05-25 19:06:59
 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
