How can I display different context menus for various types of diagram elements and the diagram area in the WPF Diagram (SfDiagram)?

In the WPF Diagram, you can display different context menus for various types of diagram elements and the diagram area by handling the MenuOpening event. This event informs you of the diagram element and the diagram on which the right-click action was performed. Within this event, you can configure different context menus based on the diagram elements or the diagram area. Below is a code example demonstrating how to achieve this.

Code Snippet :

//Here diagram is the instance of the SfDiagram.

(diagram.Info as IGraphInfo).MenuOpening += MainWindow_MenuOpening;

private void MainWindow_MenuOpening(object sender, MenuOpeningEventArgs args)
{
    var frameworkElement = (FrameworkElement)sender;
    diagram.Menu.MenuItems.Clear();
    if (frameworkElement != null)
    {
        var shapeDataContext = args.Source;
        if (shapeDataContext is NodeViewModel)
        {
            diagram.Menu.MenuItems.Add(new DiagramMenuItem()
            {
                Content = "Cut",
                CommandParameter = "Cut"
            });

            diagram.Menu.MenuItems.Add(new DiagramMenuItem()
            {
                Content = "Copy",
                CommandParameter = "Copy"
            });

        }

        else if (shapeDataContext is ConnectorViewModel)
        {
            diagram.Menu.MenuItems.Add(new DiagramMenuItem()
            {
                Content = "Delete",
                CommandParameter = "Delete"
            });
        }
        else if (shapeDataContext is SfDiagram)
        {

            diagram.Menu.MenuItems.Add(new DiagramMenuItem()
            {
                Content = "Paste",
                CommandParameter = "Paste"
            });

        }
    }
}
