# DTS.Common.Interactivity Documentation

## 1. Purpose

This module implements an MVVM-friendly interactivity pattern for WPF applications, enabling ViewModels to request user interactions (such as notifications and confirmations) without creating direct dependencies on UI components. It provides a decoupled event-driven mechanism where ViewModels raise interaction requests via `InteractionRequest<T>`, which are handled by the View through triggers and behaviors. This pattern is commonly used in frameworks like Prism to maintain separation of concerns between presentation logic and UI implementation.

## 2. Public Interface

### Interfaces

**`INotification`**
- `string Title { get; set; }` — Gets or sets the title for the notification.
- `object Content { get; set; }` — Gets or sets the content of the notification.

**`IConfirmation : INotification`**
- `bool Confirmed { get; set; }` — Gets or sets a value indicating whether the confirmation was accepted.

**`IInteractionRequest`**
- `event EventHandler<InteractionRequestedEventArgs> Raised` — Event fired when an interaction is requested.

**`IInteractionRequestAware`**
- `INotification Notification { get; set; }` — The notification passed when the interaction request was raised.
- `Action FinishInteraction { get; set; }` — An action that can be invoked to finish the interaction.

---

### Classes

**`Notification : INotification`**

Concrete implementation of `INotification` providing `Title` and `Content` properties.

---

**`Confirmation : Notification, IConfirmation`**

Extends `Notification` and implements `IConfirmation`. Adds:
- `bool Confirmed { get; set; }` — Gets or sets a value indicating that the confirmation is confirmed.

---

**`InteractionRequest<T> : IInteractionRequest` where `T : INotification`**

Generic class for raising interaction requests.

- `event EventHandler<InteractionRequestedEventArgs> Raised` — Fired when interaction is needed.
- `void Raise(T context)`
