Rhino viewport rotate/pan/zoom event in Grasshopper

Scripting
,

Hi I got an eventlistener to work (based on other threads in here) that check if the active viewport is changed or modified:

  private void RunScript(ref object A)
  {
    A = "Test";
  }

  // <Custom additional code> 

  private RhinoView cachedActiveView;

  public Script_Instance() //constructor
  {
    RhinoView.SetActive += OnViewSetActive;
    RhinoView.Modified += OnViewModified;
  }

  // Handle the view set active event
  private void OnViewSetActive(object sender, ViewEventArgs args)
  {
    cachedActiveView = args.View;
    RhinoApp.WriteLine(">> RhinoView.SetActive");
    owner.ExpireSolution(true);
    // You can add more logic here as needed
  }

  // Handle the view modified event
  private void OnViewModified(object sender, ViewEventArgs args)
  {
    if (args.View == cachedActiveView)
    {
      RhinoApp.WriteLine(">> RhinoView.Modified");
      owner.ExpireSolution(true);
      // You can add more logic here as needed
    }
  }

However. I wish to subscribe to an event that tracks when I’m zooming, panning etc in the active viewport. Is this possible.
