Configure the Breadcrumb control

The NavBreadcrumbControl can be placed in a layout pane to enable path-style navigation. Instead of a hierarchical tree representation of a ViewApp navigation model, a breadcrumb shows a sequential path. Each segment shown in a breadcrumb represents a user selected navigation item in the path.

The following examples of tree and breadcrumb navigation apps show the different visual representations of the current location within a ViewApp navigation model. Both apps show the focus of the ViewApp is currently at the Mixing navigation item. In the case of the NavBreadcrumbControl, the user selects the triangle area within a breadcrumb segment to show the child navigation items beneath the current item. Then, the user continues the navigation path by selecting a child item beneath the current parent item shown in the breadcrumb control.

The NavBreadcrumbControl includes a property to show an Alarm Adorner. An Alarm Adorner shows aggregate alarm counts within the navigation pathway. The alarm count includes the number of alarms by severity (1-4). Semi transparent alarm counts indicate the source of the alarms is a child navigation item of the current item shown in the NavBreadcrumbControl.. Solid Alarm Adorner colors indicate the navigation item that is the source of the alarms.
