0: disclaimer: I am not informed about how the use of threading may come into play here.

1: don't use a 'while loop: it's going to degrade performance: what you need in this case is a 'hook to get all Mouse Events ... either for a Form (WndProc), or for your app (App) ... or, for every running process (global).

2: why you need a 'hook: only the Control with Focus gets the WM_MOUSEWHEEL message; you can define an EventHandler to get the 'MouseWheel status:
private void Form1_Load(object sender, EventArgs e)
{
    this.MouseWheel += OnMouseWheel;

    // assign other Controls the same EventHandler
    // dataGridView.MouseWheel += OnMouseWheel;
}

private int lastMWDelta;
private int lastMWClicks;

public Point lastMWPt;

public Control lastMWActiveControl;

private void OnMouseWheel(object sender, MouseEventArgs e)
{
    lastMWDelta = e.Delta;
    lastMWClicks = e.Clicks;
    lastMWPt = e.Location;
    lastMWActiveControl = sender as Control;

    Console.WriteLine($"wheel: control: {lastMWActiveControl.Name} delta: {lastMWDelta}");
}
If there are only specific Controls you want to get wheel events for: define the same type of EventHandler for those.

3: how do you implement a 'hook ?

a: first decide what type of 'hook is required.

b: read the articles here on CodeProject about 'hooks ... like: [^], [^], [^], [^]

Come back with code, and specific issues, or questions.
