# Documentation: DTS.Common.Behaviors Namespace

|
## 1. Purpose
|
||
|
|
|
||
|
|
This module provides a collection of WPF behaviors and utilities for the DTS CommonCore framework. It enables declarative UI interactions through attached properties and `Behavior<T>` implementations, including text trimming on focus loss, multi-selection synchronization for `ListBox` controls, custom paste command handling, and a mechanism for attaching behaviors/triggers via data templates. It also provides a reflection-based attribute system for storing string metadata on enum values and objects.
