RibbonGalleryBarItem Class
A bar item that displays a gallery.
Namespace: DevExpress.Xpf.Ribbon
Assembly: DevExpress.Xpf.Ribbon.v20.2.dll
NuGet Packages: DevExpress.WindowsDesktop.Wpf.Ribbon, DevExpress.Wpf.Navigation
Declaration
public class RibbonGalleryBarItem :
BarItem,
ILinksHolder,
IMultipleElementRegistratorSupport,
IBarNameScopeSupport,
IInputElement,
ILogicalChildrenContainer
Remarks
Use RibbonGalleryBarItem objects to add galleries to the RibbonControl.
To specify a gallery for the RibbonGalleryBarItem, use the RibbonGalleryBarItem.Gallery property. A gallery consists of gallery groups (GalleryItemGroup), each of which can display any number of gallery items (GalleryItem).
Optionally, you can implement an extended version of the created gallery that will be displayed as a popup window when the RibbonGalleryBarItem‘s Dropdown button is clicked. A dropdown gallery can be specified via the RibbonGalleryBarItem.DropDownGallery property.
By default, captions (GalleryItemGroup.Caption) of gallery groups are not visible for in-ribbon galleries. By default, the captions are visible for dropdown galleries.
Note
RibbonGalleryBarItem items are only supported within a RibbonPageGroup.
