c# - c# dotnetbar 两个listboxadv同步滚动不起作用

Question

我有两个 ListBoxAdv1 和 ListBoxAdv2，我想同步它们滚动我使用此代码并向上或向下滚动但没有更新显示其他 ListBoxAdv 中的项目我该怎么办？请帮忙

我试试这个：

 private void listBoxAdv1_Scroll(object sender, ScrollEventArgs e)
 {
        listBoxAdv2.VScrollBar.Value = listBoxAdv1.VScrollBar.Value;     
 }
 private void listBoxAdv2_Scroll(object sender, ScrollEventArgs e)
 {
       listBoxAdv1.VScrollBar.Value = listBoxAdv2.VScrollBar.Value;
 }

和这个：

private void listBoxAdv1_Scroll(object sender, ScrollEventArgs e)
{
       listBoxAdv2.Focus();
       ScrollEventArgs scrollEventArgs = new ScrollEventArgs(ScrollEventType.SmallIncrement, e.OldValue, e.NewValue, ScrollOrientation.VerticalScroll);
       listBoxAdv2_Scroll(listBoxAdv2, scrollEventArgs);
}
private void listBoxAdv2_Scroll(object sender, ScrollEventArgs e)
{

}

感谢您的许多回复！我找到解决方案：

 bool Scrolling = true;
        private void listBoxAdv1_Scroll(object sender, ScrollEventArgs e)
        {
            if (Scrolling == true)
            {
                Scrolling = false;
                listBoxAdv2.BeginUpdate();
                listBoxAdv2.AutoScrollPosition = new Point(listBoxAdv1.AutoScrollPosition.X, listBoxAdv1.AutoScrollPosition.Y);
                listBoxAdv2_Scroll(sender, e);
                listBoxAdv2.EndUpdate();
                Scrolling = true;
            }
        }

        private void listBoxAdv2_Scroll(object sender, ScrollEventArgs e)
        {
            if (Scrolling == true)
            {
                Scrolling = false;
                listBoxAdv1.BeginUpdate();
                listBoxAdv1.AutoScrollPosition = new Point(listBoxAdv2.AutoScrollPosition.X, listBoxAdv2.AutoScrollPosition.Y);
                listBoxAdv1_Scroll(sender, e);
                listBoxAdv1.EndUpdate();
                Scrolling = true;
            }
        }
