同时滚动两个面板c# winForms

是的，所以我有两个宽度相同且数据宽度相同的面板。顶部面板启用了自动滚动。我希望能够使用顶部面板滚动条滚动两个面板。这意味着底部面板没有滚动条。我该怎么做呢？

编辑：我尝试了 panel2.AutoScrollPosition = panel1.AutoScrollPosition; 没有

我也

e.Graphics.DrawRectangle(new Pen(Color.Pink,3), 10, 10, 30, 20);
        e.Graphics.TranslateTransform(panel1.AutoScrollPosition.X, 0);

尝试在矩形上进行任何移动。我做错了什么？

yea so I have 2 panels with the same width and the same width of data in them. the top panel has autoscroll enabled. I would like to be able to scroll both panels, with the top panel scrollbar. which means that the bottom panel doesn't have a scroll bar. How would I do that?

EDIT: I tried panel2.AutoScrollPosition = panel1.AutoScrollPosition;
nothing

I also tried

e.Graphics.DrawRectangle(new Pen(Color.Pink,3), 10, 10, 30, 20);
        e.Graphics.TranslateTransform(panel1.AutoScrollPosition.X, 0);

no movement on the rectangle.
What am i doing wrong?

简单易行。为第一个面板实现 Scroll 事件，并使其在第二个面板上 Invalidate()。使用第一个面板的滚动位置在第二个面板的 Paint 事件中绘制文本：

    private void panel1_Scroll(object sender, ScrollEventArgs e) {
        panel2.Invalidate();
    }

    private void panel2_Paint(object sender, PaintEventArgs e) {
        Point pos = new Point(panel1.AutoScrollPosition.X, 0);
        TextRenderer.DrawText(e.Graphics, "nobugz waz here", panel2.Font, pos, Color.Black);
        // Draw something
        e.Graphics.TranslateTransform(pos.X, pos.Y);
        e.Graphics.DrawLine(Pens.Black, 0, 0, 100, 100);
    }

Easy peasy. Implement the Scroll event for the 1st panel and have it Invalidate() the 2nd. Draw the text in the 2nd panel's Paint event, using the scroll position of the 1st:

    private void panel1_Scroll(object sender, ScrollEventArgs e) {
        panel2.Invalidate();
    }

    private void panel2_Paint(object sender, PaintEventArgs e) {
        Point pos = new Point(panel1.AutoScrollPosition.X, 0);
        TextRenderer.DrawText(e.Graphics, "nobugz waz here", panel2.Font, pos, Color.Black);
        // Draw something
        e.Graphics.TranslateTransform(pos.X, pos.Y);
        e.Graphics.DrawLine(Pens.Black, 0, 0, 100, 100);
    }
