当设定 VerticalScroll.Value 在面板与自动滚屏设置为真，滚动位置相应地改变，但大拇指的位置没有。我是否需要以某种方式更新滚动条（的Invalidate（TRUE）在面板上不工作）？任何想法？

When setting VerticalScroll.Value in a Panel with AutoScroll set to true, the scroll position changes accordingly but the position of the thumb does not. Do I need to update the scrollbar somehow (Invalidate(true) on the panel does not work)? Any ideas?

推荐答案

尝试调用.PerformLayout();
