c# – 如何以编程方式滚动面板

public void ScrollToBottom(Panel p){
  using (Control c = new Control() { Parent = p,Dock = DockStyle.Bottom })
     {
        p.ScrollControlIntoView(c);
        c.Parent = null;
     }
}
//use the code
ScrollToBottom(yourPanel);

或使用扩展方法方便：

public static class PanelExtension {
   public static void ScrollToBottom(this Panel p){
      using (Control c = new Control() { Parent = p,Dock = DockStyle.Bottom })
      {
         p.ScrollControlIntoView(c);
         c.Parent = null;
      }
   }
}
//Use the code
yourPanel.ScrollToBottom();

UPDATE

如果要设置确切位置,请稍后修改代码可以帮助您：

//This can help you control the scrollbar with scrolling up and down.
//The position is a little special.
//Position for scrolling up should be negative.
//Position for scrolling down should be positive
public static class PanelExtension {
    public static void ScrollDown(this Panel p,int pos)
    {
        //pos passed in should be positive
        using (Control c = new Control() { Parent = p,Height = 1,Top = p.ClientSize.Height + pos })
        {
            p.ScrollControlIntoView(c);                
        }
    }
    public static void ScrollUp(this Panel p,int pos)
    {
        //pos passed in should be negative
        using (Control c = new Control() { Parent = p,Top = pos})
        {
            p.ScrollControlIntoView(c);                
        }
    }
}
//use the code,suppose you have 2 buttons,up and down to control the scrollbar instead of clicking directly on the scrollbar arrows.
int i = 0;
private void buttonUp_Click(object sender,EventArgs e)
{
   if (i >= 0) i = -1;
   yourPanel.ScrollUp(i--);
}
private void buttonDown_Click(object sender,EventArgs e)
{
   if (i < 0) i = 0;
   yourPanel.ScrollDown(i++);
}

您可能想要使用的另一个解决方案是使用Panel.VerticalScroll.Value.不过,我认为你需要更多的研究,使它按照你的期望工作.因为我可以看到一旦改变了值,滚动条位置和控制位置就不能很好的同步.请注意,Panel.VerticalScroll.Value应位于Panel.VerticalScroll.Minimum和Panel.VerticalScroll.Maximum之间.
