Change the background color of a VscrollBar

Question

Is it possible to change the background color of a VscrollBar? The best approach I have consulted is http://www.codeproject.com/Articles/624997/Enhanced-Scrollbar or http://www.codeproject.com/Articles/41869/Custom-Drawn-Scrollbar , but no exists BackColor property, and BackgroundImage not works.

I tried the simplest thing like:

public class ScrollBarEx : VScrollBar
{
    protected override void OnPaint(PaintEventArgs e)
    {
        base.BackColor = Color.Red;
        base.Invalidate();
    }
}

It does not work. Any suggestions?

没有太多新信息，但是：您必须处理Paint事件并做滚动条的自定义绘制，这是此解决方案的另一个链接（通过Paint事件进行自定义绘制） http://www.codeproject.com/Articles/14801 /如何对皮肤的滚动条换面板，在-C

I built my own custom ScrollBar control based on http://www.codeproject.com/Articles/41869/Custom-Drawn-Scrollbar .

My custom ScrollBar comes with ready-to-use themes (VS 2019 Dark and VS 2019 Light). You can change the control background color by modifying the field _backColor or you can expose this private field with a property to allow you to change the background color from the code.

I have modified the original control to get rid of the 3D colors and replaced them with flat colors
