NavBarControl Class

Implements a side navigation UI found in MS Office or MS Explorer.

Namespace:DevExpress.XtraNavBar
Assembly:DevExpress.XtraNavBar.v17.1.dll

Expanded Syntax

Expanded Remarks

The NavBarControl displays links (commands) combined into groups. Groups of links can be expanded/collapsed in order to show/hide their contents.

The NavBarControl supports three paint views: Navigation Pane, Explorer Bar View and Side Bar View. Each of these views behave and display their contents (links) differently. The Navigation Pane and Side Bar View display the content of a single group simultaneously, while the Explorer Bar View provides simultaneous access to the content of all groups. The following image shows a NavBarControl where the Navigation Pane View is enabled:

You can select the view using the PaintStyleKind property. At design time, use the control's Designer to preview available paint views. For more information, see the Views topic.

The NavBarControl class contains two properties representing collections of groups and items. Groups are accessed via the Groups property. Each group within the collection contains its collection of links. Links reference items which are stored in the Items property of the control. This structure allows you to display links to the same item in different groups, or several times within the same group. See Navigation Bar for more details.

An end-user can click a specific link, and this fires the LinkClicked and NavBarItem.LinkClicked events, which you can handle to perform custom actions.

You can also enable link selection using the LinkSelectionMode property. When this feature is enabled, a link remains in the depressed state once clicked. To respond to link selection, handle the SelectedLinkChanged event (instead of the link click events mentioned above).

Expanded Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E5096.

This example shows how to create a NavBarControl in code.

The NavBarControl will have two groups ('Charts' and 'Settings') with items. Item link selection is enabled by setting the LinkSelectionMode property to LinkSelectionModeType.OneInGroupAndAllowAutoSelect. To respond to a link selection, the SelectedLinkChanged event is handled.



In the OneInGroupAndAllowAutoSelect mode, each group can have a single selected link independent of other groups. When a group is activated and it has no selected link, the first link is auto-selected. At runtime, you will see that the SelectedLinkChanged event fires on group activation, while the LinkClicked event does not.



The example demonstrates two methods of assigning images to navbar items:

1) explicit assignment of Image objects to items (see the 'Charts' navbar group item initialization);

2) implicit assignment, using image indexes (see the 'Settings' navbar group item initialization).
