Property Value

TypeDescription
RibbonBarItems

A RibbonBarItems object that represents the collection of bar items.

|

Remarks

This collection stores bar items that can be used within the current RibbonControl. If you want to use a bar item within the Ribbon Control ensure that it’s added to the Items collection.

If a bar item is created at design time using the RibbonControl’s designer it’s automatically added to the Items collection. If a bar item is created in code, you need to add it to the collection manually or use one of the following methods of creating bar items that will add the created item to the collection:

For more information on bar items, see Items and Item Links.

Example

This example creates DevExpress WinForms RibbonControl and RibbonStatusBar:

  • The RibbonControl contains the “Home” page, “File” and “Print” groups, and four commands (bar items).
  • The RibbonStatusBar displays the “Print” command. The “Print” command is aligned to the right.

The following animation shows the result:

Prerequisites

In this example, the SvgImageCollection was created and populated with SVG images at design-time.

Note

When creating the Ribbon UI in code, ensure that the following requirements are met:

  1. All bar items are added to the RibbonControl.Items collection.
  2. All bar items have unique identifiers (the BarItem.Id property should be set to a unique value).
