Event Data

The RegisterItem event's data class is DevExpress.XtraBars.Navigation.NavigationBarNavigationClientItemEventArgs.

Remarks

When you set the OfficeNavigationBar.NavigationClient property to an INavigationBarClient object, for each element in the INavigationBarClient.ItemsSource list, a ClientNavigationBarItem is automatically added to the OfficeNavigationBar.Items collection. For these items, the RegisterItem event fires allowing you to perform additional item customization.

When the OfficeNavigationBar.NavigationClient property is cleared, the automatically created items are removed from the OfficeNavigationBar.Items collection and the OfficeNavigationBar.UnregisterItem event fires for each of them.

Currently, the INavigationBarClient interface is implemented by the NavBarControl. The NavBarControl’s INavigationBarClient.ItemsSource property returns a collection of NavBarGroups, specified by the NavBarControl.Groups property.
