C#ListView鼠标滚轮没有焦点

我正在制作一个WinForms应用程序,其中ListView设置为详细信息,以便可以显示多个列.

当鼠标悬停在控件上并且用户使用鼠标滚轮时,我希望此列表滚动.现在,滚动仅在ListView具有焦点时发生.

即使没有焦点,我怎样才能使ListView滚动？

"简单"和工作解决方案:

public class FormContainingListView : Form, IMessageFilter
{
    public FormContainingListView()
    {
        // ...
        Application.AddMessageFilter(this);
    }

    #region mouse wheel without focus

    // P/Invoke declarations
    [DllImport("user32.dll")]
    private static extern IntPtr WindowFromPoint(Point pt);
    [DllImport("user32.dll")]
    private static extern IntPtr SendMessage(IntPtr hWnd, int msg, IntPtr wp, IntPtr lp);

    public bool PreFilterMessage(ref Message m)
    {
        if (m.Msg == 0x20a)
        {
            // WM_MOUSEWHEEL, find the control at screen position m.LParam
            Point pos = new Point(m.LParam.ToInt32() & 0xffff, m.LParam.ToInt32() >> 16);
            IntPtr hWnd = WindowFromPoint(pos);
            if (hWnd != IntPtr.Zero && hWnd != m.HWnd && System.Windows.Forms.Control.FromHandle(hWnd) != null)
            {
                SendMessage(hWnd, m.Msg, m.WParam, m.LParam);
                return true;
            }
        }
        return false;
    }

    #endregion
}
