如何触发 FlowLayoutPanel 的滚动事件？

Question

这是我的代码：

public partial class Form1 : Form {

  public Form1() {
    InitializeComponent();

    for (int i = 0; i < 10; i++) {
      Button btn = new Button();
      btn.Text = "TEST";
      btn.Height = 35;

      this.flowLayoutPanel1.Controls.Add(btn);
    }

    this.flowLayoutPanel1.AutoScroll = true;
    this.flowLayoutPanel1.Scroll += FlowLayoutPanel1_Scroll;
  }

  private void FlowLayoutPanel1_Scroll(object sender, ScrollEventArgs e) {
    MessageBox.Show("Event Triggered");
  }
}

下面是 UI 的样子：

当我在 flowlayoutpanel 中使用鼠标滚轮滚动时，似乎没有触发滚动事件

解决方案应该不难找到，但是我坚持了几个小时.. 谁能给我指出一些方向？谢谢！！

有一个特殊的MouseWheel事件捕获了这个

flowLayoutPanel1.MouseWheel += FlowLayoutPanel1_MouseWheel;

private void FlowLayoutPanel1_MouseWheel(object sender, MouseEventArgs e)
{
    Console.WriteLine("Scrolling Wheel");
}
