Hello
I create a plugin to send some data (like active view, mouse position,…) from Rhino to Grasshopper.
This work fine but the c# component always alive like when we use timer.

Is there a way to make the c# component run only when a new data received from Rhino?
Or maybe a way to receive data without importing the plugin?

Code in the plugin:

using Rhino.Display;
using Rhino.PlugIns;

namespace RhinoToGrasshopper
{
    public class RhinoToGrasshopperPlugin : PlugIn
    {
        public RhinoToGrasshopperPlugin()
        {
            Instance = this;
            RhinoView.SetActive += OnViewSetActive;
            RhinoView.Modified += OnViewModified;
        }

        public override PlugInLoadTime LoadTime => PlugInLoadTime.AtStartup;
        public static RhinoToGrasshopperPlugin Instance { get; private set; }

        public static string viewname;

        private static void OnViewSetActive(object sender, ViewEventArgs args)
        {
            viewname = args.View.ActiveViewport.Name;
        }

        private static void OnViewModified(object sender, ViewEventArgs args)
        {
            viewname = args.View.ActiveViewport.Name;
        }

        public static void ActiveView()
        {
            using (var args = new Rhino.Runtime.NamedParametersEventArgs())
            {
                args.Set("activeview_name", viewname);
                Rhino.Runtime.HostUtils.ExecuteNamedCallback("RhinoActiveView", args);
            }
        }
    }
}

Code in Grasshopper:

using RhinoToGrasshopper;  // import RhinoToGrasshopper.rhp
-------------------------------------------------------------------------------
RhinoToGrasshopperPlugin.ActiveView(); // import this from the plugin to enable receiving data
Receive(Component);
Active_View_Name = str;
-------------------------------------------------------------------------------
string str = null;
bool registered = false;
IGH_Component comp = null;

void Receive(IGH_Component component)
{
  if(!registered)
  {
    Rhino.Runtime.HostUtils.RegisterNamedCallback("RhinoActiveView", RiRhino);
    comp = component;
    registered = true;
  }
}

void RiRhino(object sender, Rhino.Runtime.NamedParametersEventArgs args)
{
  string values;
  if (args.TryGetString("activeview_name", out values))
  {
    str = values;
  }
  comp.ExpireSolution(true);
}

This is an example from Rhinino inside Unity to watch the code

var ghWatcher = new GameObject("Grasshopper Geometry");
ghWatcher.AddComponent<GrasshopperInUnity>();

How we can do the same in Rhino?
