OfficeNavigationBar.NavigationClient Property

Assign a NavBarControl or AccordionControl to this property to automatically fill this OfficeNavigationBar with items that match NavigationClient’s groups. If the OfficeNavigationBar.AllowItemSelection property is enabled, OfficeNavigationBar item selection forces the NavigationClient to select a corresponding group.

Namespace: DevExpress.XtraBars.Navigation

Assembly: DevExpress.XtraBars.v19.1.dll

Declaration

C#

[DefaultValue(null)]
[DXCategory("Navigation Client")]
public INavigationBarClient NavigationClient { get; set; }

VB.NET

<DefaultValue(Nothing)>
<DXCategory("Navigation Client")>
Public Property NavigationClient As INavigationBarClient

Property Value

Type	Default	Description
DevExpress.Utils.Navigation.INavigationBarClient	*null*	A control that implements the INavigationBarClient interface which serves as an item source for this OfficeNavigationBar.

Remarks

The animation below illustrates an OfficeNavigationBar with three items. When a user selects an item, the NavBarControl automatically activates the corresponding group. Animation effects are provided by the Navigation Frame control.

This interaction fails if:

• the OfficeNavigationBar.AllowItemSelection setting is disabled;
• the NavBarControl is in Explorer Bar View.

Note

OfficeNavigationBar items retrieved from NavigationClient groups are initialized when the application starts, and do not exist at design time. For that reason, do not use the OfficeNavigationBar.SelectedItem property at design time to choose the initially selected OfficeNavigationBar item \ NavigationClient group. Instead, use the AccordionControl.SelectedElement and NavBarControl.ActiveGroup properties of the NavigationClient.

To customize auto-generated OfficeNavigationBar items, handle the OfficeNavigationBar.RegisterItem event. The following sample illustrates how to assign the same vector icons Accordion groups use to OfficeNavigationBar items.

C#

private void officeNavigationBar1_RegisterItem(object sender, DevExpress.XtraBars.Navigation.NavigationBarNavigationClientItemEventArgs e) {
    e.Item.ImageOptions.SvgImageSize = new Size(24, 24);
    e.Item.ImageOptions.SvgImage = (e.NavigationItem as AccordionControlElement).ImageOptions.SvgImage;
}

VB.NET

Private Sub officeNavigationBar1_RegisterItem(ByVal sender As Object, ByVal e As DevExpress.XtraBars.Navigation.NavigationBarNavigationClientItemEventArgs)
    e.Item.ImageOptions.SvgImageSize = New Size(24, 24)
    e.Item.ImageOptions.SvgImage = (TryCast(e.NavigationItem, AccordionControlElement)).ImageOptions.SvgImage
End Sub
