Like this?

 

In Main:

List<Grasshopper.Kernel.Parameters.Param_GenericObject> objects
      = FindObjectsInCurrentGroup<Grasshopper.Kernel.Parameters.Param_GenericObject>();

Function:

private List<T> FindObjectsInCurrentGroup<T>() where T : Grasshopper.Kernel.IGH_DocumentObject
  {    
    List<Grasshopper.Kernel.Special.GH_Group> groups = GrasshopperDocument
      .Objects
      .OfType<Grasshopper.Kernel.Special.GH_Group>()
      .Where(gr => gr.ObjectIDs.Contains(Component.InstanceGuid))
      .ToList<Grasshopper.Kernel.Special.GH_Group>();

    Print("{0}", groups.Count);
    List<T> output = groups.Aggregate(new List<T>(), (list, item) =>
      {
      list.AddRange(
        GrasshopperDocument.Objects.OfType<T>()
        .Where(obj => item.ObjectIDs.Contains(obj.InstanceGuid))
        );
      return list;
      }).Distinct().ToList();

    return output;
  }

Why Grasshopper.Kernel.Parameters.Param_GenericObject ? That will not find the Panel as Panel doesn't derive from Param_GenericObject.

Here we are (again: accept my apologies).

Moral of all these: Buy a proper Ducati, what else? (see def)

Hmm ... I suspect that you want to find all groups in the document otherwise it doesn't make much sense ... or maybe it does who knows? he he.
