The old ASPxDashboardViewer control and the MVCxDashboardViewer extension do not support the Tab container dashboard item as compared to ASPxDashboard / MVCxDashboard. When ASPxDashboardViewer / MVCxDashboardViewer opens a dashboard with a tab container, a client-side exception occurs. It is necessary to show the corresponding pop-up message in a dashboard UI instead.
