Question

我有两个ListBoxAdv1和ListBoxAdv2，我希望同步它们滚动我使用此代码只是向上或向下滚动，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;
 }

和此：

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)
{

}

感谢许多回复！我找到了解决方案：

 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;
            }
        }
