How to move objects from one layer to another ?Using diagram.MoveObjects - is not working

How to move objects(Nodes) between Layers.Objects are not visible until I add it to new Layer,when I add it to existing Layer -Objects (Nodes) are not visible. 
If I create a new Layer whenever I add new Objects-I was not able to access the Objects from other layers or it is Lying behind the new layer or invisible?So,I decided to have all nodes in one Layer ,whenever i add new Objects/Nodes ,I should be able to Move them to existing Layer and access them.
Nodes are not visible in the below sample. 
Bogenlayer-Is already existing Layer with Nodes/Objects
 void CreateEmptyNodes()
    {
        var li = new ObservableCollection<DiagramNode>();
         List<String> EmptyObjlist = new List<String>();
        string[] EmptyObj = new string[20];
        for(int i=0;i<20;i++)
        {
            li.Add(new DiagramNode()
            {
                Id = "Emptynode"+li.Count,
                //Size of the node
                Width = 100,
                Height = 100,
                //Position of the node
                OffsetX = 300,
                OffsetY = 500,
                Pivot = new NodePivotPoint() { X = 0, Y = 0 },
                Shape = new DiagramShape() { Type = Shapes.Basic, BasicShape = Syncfusion.EJ2.Blazor.Diagrams.BasicShapes.Rectangle },
                Style = new NodeShapeStyle() { Fill = "#ff0000", StrokeColor = "black" },
                Constraints = NodeConstraints.Default & ~(NodeConstraints.Rotate) & ~(NodeConstraints.Resize)
            });
        }
        for (int i = 0; i < li.Count; i++)
        {
            EmptyObjlist.Add(li[i].Id);
            EmptyNodeCollection.Add(li[i]);
            NodeCollection.Add(li[i]);
        }
         EmptyObj = EmptyObjlist.ToArray();
         //Layers.Add(new DiagramLayer() { Id = "Emptylayer", Visible = true, Objects = EmptyObj, Lock = false });
         diagram.MoveObjects(EmptyObj,"Bogenlayer");

         diagram.BringLayerForward("Bogenlayer");
         diagram.SetActiveLayer("Bogenlayer");
         Layers.Where((layer) => layer.Id == "Bogenlayer").FirstOrDefault().Visible = true;
      
      
         StateHasChanged();
    }
Nodes are  visible in below 
 void CreateEmptyNodes()
    {
        var li = new ObservableCollection<DiagramNode>();
         List<String> EmptyObjlist = new List<String>();
        string[] EmptyObj = new string[20];
        for(int i=0;i<20;i++)
        {
            li.Add(new DiagramNode()
            {
                Id = "Emptynode"+li.Count,
                //Size of the node
                Width = 100,
                Height = 100,
                //Position of the node
                OffsetX = 300,
                OffsetY = 500,
                Pivot = new NodePivotPoint() { X = 0, Y = 0 },
                Shape = new DiagramShape() { Type = Shapes.Basic, BasicShape = Syncfusion.EJ2.Blazor.Diagrams.BasicShapes.Rectangle },
                Style = new NodeShapeStyle() { Fill = "#ff0000", StrokeColor = "black" },
                Constraints = NodeConstraints.Default & ~(NodeConstraints.Rotate) & ~(NodeConstraints.Resize)
            });
        }
        for (int i = 0; i < li.Count; i++)
        {
            EmptyObjlist.Add(li[i].Id);
            EmptyNodeCollection.Add(li[i]);
            NodeCollection.Add(li[i]);
        }
         EmptyObj = EmptyObjlist.ToArray();
         Layers.Add(new DiagramLayer() { Id = "Emptylayer", Visible = true, Objects = EmptyObj, Lock = false });
         diagram.MoveObjects(EmptyObj,"Bogenlayer");

         diagram.BringLayerForward("Bogenlayer");
         diagram.SetActiveLayer("Bogenlayer");
         Layers.Where((layer) => layer.Id == "Bogenlayer").FirstOrDefault().Visible = true;
      
      
         StateHasChanged();
    }
