# Documentation: DTS.Common.RibbonControl

## 1. Purpose

This module provides Prism region adapter support for integrating WPF `Ribbon` controls with the Prism navigation framework. It enables dynamic addition and removal of `RibbonTab` items through region management, synchronizes tab selection between document/workspace views and the ribbon, and publishes selection change events via the Prism event aggregator. The module bridges the gap between Prism's region-based view composition and the WPF Ribbon control's item management model.
