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

[Mounika]

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();

    }
