I am creating diagram component for first time Link Delete event works properly. Now my problem is that when ever i am drawing the diagram again using the same component instance it draws perfectly no problem but now if i want delete the link it does not work.

Can you please let me know where I am going wrong. Do I need to call any other API which before drawing the diagram again?

Thanks

Yes I am pressing delete key. It does not delete link as well as not raising any event.

Actually i am Working on Angular and have created the component. I have constructed the component instance only once and provided the data when ever anything change in data. Diagram get drawn properly but facing problem when we want to delete the link.

When ever any data gets changed below method will get called.

set dataSource(value) {
        // create a Diagram component that wraps the 'diagram' canvas
        if (value !== undefined && value !== null) {
            this.diagramModel = value;

            this.diagram = Diagram.create(document.querySelector('#diagram'));
            this.diagram.clearAll();
            this.diagram.setBehavior(MindFusion.Diagramming.Behavior.DoNothing);
            this.diagram.setAutoResize(MindFusion.Diagramming.AutoResize.AllDirections);
            this.diagram.setEnabled(false);
            this.prepareTreeGraph(this.diagramModel.containerNodes, this.diagramModel.links, this.diagramModel.attributes);
        }
    }
 

Can you please let me know is there any api for initializing diagram?
