# Documentation: DTS.Common.RibbonControl

## 1. Purpose

This module provides Prism region adapter support and event infrastructure for integrating WPF `Ribbon` controls into a Prism-based application. It enables dynamic addition and removal of `RibbonTab` and `RibbonApplicationMenu` items through Prism's region management system, synchronizes tab selection between document/workspace views and ribbon tabs via event aggregation, and exposes selection change notifications for consumers to react to ribbon tab changes.
