NavBarGroup Class

Represents an individual group within the NavBarControl.

Namespace:DevExpress.Xpf.NavBar
Assembly:DevExpress.Xpf.NavBar.v19.1.dll

Expanded Syntax

Expanded Remarks

A navbar control maintains collections of groups and items. Groups are represented by instances of the NavBarGroup class which can be accessed via the NavBarControl.Groups property. This property returns the NavBarGroupCollection collection which allows you to add and delete groups within the navbar.

Use properties of the NavBarGroup class to specify the appearance and behavior of an individual group. Use the Header and ImageSource properties to define the caption text of a group and an image to be displayed within the group's header. A group's visibility can be controlled via the IsVisible property. The content of a group can be defined by either the Items or Content property, depending upon the DisplaySource property setting.

Set the IsExpanded property to true to expand a group; set it to false to collapse it. Use the SelectedItem or SelectedItemIndex property to determine a group's selected item.

Using the VisualStyle property you can define a visual style to be applied to a group. The appearance of a group's items can be controlled by using the ItemVisualStyle property.

To learn more, see the Groups topic.

Expanded Example

This example demonstrates how items can be created and customized programmatically within a navbar group.

In this sample, images are defined for the group header and the third group item via the ImageSource and NavBarItem.ImageSource properties, respectively. The item image's layout is customized by assigning the item's NavBarItem.VisualStyle property with a specific style that makes use of the NavBarViewBase.LayoutSettings attached property's LayoutSettings.ImageDocking setting.
