The Telerik RadRibbonBar control enables you to build user interfaces similar to the “wave of the future” ribbonbar used by Microsoft Office 2007. This feature ensures your applications will have a similar look to the most up-to-date Microsoft applications that users will know. The RadControls suite for WinForms supplies a variety of controls that you can host in the RadRibbonBar including themeable check boxes, split buttons, repeat buttons, drop-down buttons, and more.

RadApplicationMenu is the Telerik counterpart of the "application menu" introduced with Office 2007 as part of Microsoft’s Ribbon UI. Based on RadMenuStrip, it displays controls used to perform actions on entire documents and forms, such as Save and Print. It also provides a list of recent documents, access to form options, and the ability to exit the form or application.

RadApplicationMenu is fully compliant with the 2007 Microsoft® Office Fluent™ User Interface Design Guidelines.

To save space, you can collapse the RadRibbonBar by double-clicking the selected tab. The entire bottom part disappears, leaving only a single row of tabs across the top.

Each RadRibbonBar tab can host one or more chunks. A chunk is a container for the other containers and individual functional elements. Chunks can individually collapse if there is not enough room to display them all. Chunks may contain one or more button groups. A button group is a container that can contain other nested button groups or individual functional elements. Button groups can be oriented horizontally (containing a horizontal row of elements) or vertically (containing a vertical column of elements).

When the RibbonBar is being resized, and more specifically when it's getting smaller, it automatically collapses the tool chunks to save space. Respectively when its getting larger it expands the chunks for which there's available space.

Unlike some ribbon implementations, the Telerik RadRibbonBar was built with ease of design in mind. You can build an entire ribbon in the Windows Forms designers by manipulating tabs, chunks, and controls directly, without writing any code. Then customize the appearance with the unique VisualStyleBuilder to give it the final look and feel for your own application.

The Start Button provides convenient access to the Start Menu of important commands. This button can be customized to fit many needs including to aid in corporate branding.

The Quick Access Menu above the ribbon tabs can be used for customization or frequently-used commands. This feature is a great productivity boost for users who often need to utilize the same commands in a majority of their work.

With a RadRibbonBar, you can organize all of the functionality of your application into a single compact ribbon containing an almost unlimited number of nested controls. The ribbon splits your application’s controls into a natural hierarchy starting with tabs of major functionality. Tabs include chunks, which in turn contain an unlimited number of controls including toolbars, customizable buttons, and combo boxes.
