Hi
In Rhino view properties tab, the name of the active view and other settings changed automatically when the viewport changed
What is the event used and how to use it in c#?

Hi @anon39580149,

There are a number of RhinoView events you can subscribe to:

RhinoView.Modified is probably what you want.

Hi @anon39580149,

Maybe this?

public class TestSeghier : Command
{
  public TestSeghier()
  {
    Instance = this;
    RhinoView.SetActive += OnViewSetActive;
    RhinoView.Modified += OnViewModified;
  }

  public static TestSeghier Instance { get; private set; }

  public override string EnglishName => "TestSeghier";

  private static void OnViewSetActive(object sender, ViewEventArgs args)
  {
    RhinoApp.WriteLine(">> RhinoView.SetActive");
  }

  private static void OnViewModified(object sender, ViewEventArgs args)
  {
    RhinoApp.WriteLine(">> RhinoView.Modified");
  }

  protected override Result RunCommand(RhinoDoc doc, RunMode mode)
  {
    return Result.Success;
  }
}

Thank you very much @dale
I will test it

Use the ViewEventArgs parameter passed to the events to get information about which view you are being informed about

I use RhinoView event with Rhinoinside to get activeview in Grasshopper.
I will try more events
