    public partial class Form1 : XtraForm

            InitializeComponent();
            // Create a RibbonControl.
            RibbonControl Ribbon = new RibbonControl();
            // Create the 'Home' page.
            RibbonPage pageHome = new RibbonPage("Home");
            Ribbon.Pages.Add(pageHome);
            // Create the 'Selection' page category.
            RibbonPageCategory catSelection = new RibbonPageCategory("Selection", Color.Orange, false);
            Ribbon.PageCategories.Add(catSelection);
            // Create 'Format' an 'Clipboard' contextual pages/tabs in the 'Selection' page category.
            RibbonPage contextPageFormat = new RibbonPage("Format");
            RibbonPage contextPageClipboard = new RibbonPage("Clipboard");
            catSelection.Pages.AddRange(new RibbonPage[] { contextPageFormat, contextPageClipboard });

            // Add the 'Edit' group with two bar items to the 'Format' page.
            RibbonPageGroup groupEdit = new RibbonPageGroup("Edit") { AllowTextClipping = false };
            // Add two bar items to the 'Edit' group.
            BarButtonItem itemCopy = new BarButtonItem(Ribbon.Manager, "Copy"){ RibbonStyle = RibbonItemStyles.Large};
            itemCopy.ImageOptions.SvgImage = svgImageCollection1["copy"];
            BarButtonItem itemCut = new BarButtonItem(Ribbon.Manager, "Cut") { RibbonStyle = RibbonItemStyles.Large };
            itemCut.ImageOptions.SvgImage = svgImageCollection1["cut"];
            groupEdit.ItemLinks.AddRange(new BarItem[] { itemCopy, itemCut });
            contextPageFormat.Groups.Add(groupEdit);
            Ribbon.ItemClick += new ItemClickEventHandler(Ribbon_ItemClick);

            // Add the RibbonControl to the form.
            this.Controls.Add(Ribbon);

            /* Contextual pages are hidden by default.
             * The following line displays the 'Selection' page category.
             */
            catSelection.Visible = true;
            // Activate the 'Format' contextual page/tab.
            Ribbon.SelectedPage = catSelection.Pages["Format"];
        }
        void Ribbon_ItemClick(object sender, ItemClickEventArgs e)
        {
            // Add your code to handle clicks on bar items.
