Assembly: DevExpress.XtraNavBar.v24.2.dll

NuGet Package: DevExpress.Win

#Declaration

public virtual NavBarGroup Add()

#Returns

Type Description
NavBarGroup

A NavBarGroup object representing the newly created group.

#Remarks

Use the Add method to add a new group to the NavBarControl. Modify properties of the obtained object to control the appearance and behavior of the added group.

You can access the collection of group links via the NavBarGroup.ItemLinks property. Use the NavLinkCollection.Add method of the obtained collection to add links to the group.

#Example

The following sample code demonstrates how to add and modify groups, items and links between them. All elements are added via the Add method of the corresponding collection.

Captions are assigned to the added group and two items. This is performed via the NavElement.Caption property of the NavBarGroup and NavBarItem objects respectively. The NavElement.ImageOptions property is used to display images within links.

The following image shows the control before and after code execution.
