RibbonPageCategory.Visible Property

Gets or sets whether the current category is visible.

Namespace: DevExpress.XtraBars.Ribbon

Assembly: DevExpress.XtraBars.v20.1.dll


public bool Visible { get; set; }
Public Property Visible As Boolean

Property Value

Type Default Description


true if the category is visible; otherwise, false.


If the Visible property is set to false, all pages that belong to the current category are hidden. To control the visibility of individual pages, use the RibbonPage.Visible property.


The following example demonstrates how to create contextual tab pages in the RibbonControl in code.

In the example, a RibbonControl control is created containing one permanently displayed page ("Home") and two contextual pages ("Format" and "Clipboard"). The contextual pages are combined into a custom page category ("Selection").

Contextual pages are hidden when they are created. They are made visible later via the category's RibbonPageCategory.Visible property.

The following image demonstrates code execution:


using DevExpress.XtraBars.Ribbon;
using DevExpress.XtraBars;

// Create a RibbonControl.
RibbonControl Ribbon = new RibbonControl();
// Assign a collection of images that will be used by bar items.
Ribbon.Images = imageCollection1;            
// Create a page and associate it with the default category.
RibbonPage pageHome = new RibbonPage("Home");
// Create a custom Selection page category.
RibbonPageCategory catSelection = new RibbonPageCategory("Selection", Color.LightPink, false);
// Create two contextual pages (Format an Clipboard)in the Selection category.
RibbonPage contextPageFormat = new RibbonPage("Format");
RibbonPage contextPageClipboard = new RibbonPage("Clipboard");
catSelection.Pages.AddRange(new RibbonPage[] {contextPageFormat, contextPageClipboard});

// Customize the Format page by adding a Format group with two bar items to it.
RibbonPageGroup groupFormat = new RibbonPageGroup("Format");
groupFormat.AllowTextClipping = false;
// Add two items to the Format group
BarButtonItem itemCopy = new BarButtonItem(Ribbon.Manager, "Copy", 0);
BarButtonItem itemCut = new BarButtonItem(Ribbon.Manager, "Cut", 1);
groupFormat.ItemLinks.AddRange(new BarItem[] {itemCopy, itemCut});
// Subscribe to an event which fires when any item is clicked.
Ribbon.ItemClick += new ItemClickEventHandler(Ribbon_ItemClick);

// Add the RibbonControl to the form.


// Make the Selection category visible
catSelection.Visible = true;
// Activate the category's first page.
Ribbon.SelectedPage = catSelection.Pages[0];

// Respond to item clicking.
void Ribbon_ItemClick(object sender, ItemClickEventArgs e) {
