Remarks

This class represents a collection of RibbonPageCategory objects. It provides methods to add, remove and access elements in the collection.

The RibbonControl provides the RibbonControl.PageCategories property representing a collection of custom page categories. Use custom page categories to implement contextual tabs, as in the Microsoft Office 2007 UI. See Categories and Contextual Tabs to learn more.

Example

The following example creates the DevExpress WinForms Ribbon Control with two contextual tabs/pages. The svgImageCollection1 was added and populated with SVG images at design time.

            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.

            catSelection.Pages.AddRange(new RibbonPage[] { contextPageFormat, contextPageClipboard });

            // Add the 'Edit' group with two bar items to the 'Format' page.

            itemCut.ImageOptions.SvgImage = svgImageCollection1["cut"];
            groupEdit.ItemLinks.AddRange(new BarItem[] { itemCopy, itemCut });
            contextPageFormat.Groups.Add(groupEdit);
            Ribbon.ItemClick += new ItemClickEventHandler(Ribbon_ItemClick);

            // Activate the 'Format' contextual page/tab.
            Ribbon.SelectedPage = catSelection.Pages["Format"];
