# Documentation: Channel Code Events

## 1. Purpose

This module defines two Prism event types for the event aggregation system, enabling loosely-coupled communication between components regarding channel code operations. `ChannelCodesViewChangedEvent` notifies subscribers when the channel codes view mode changes, while `ChannelCodeCommittedEvent` broadcasts when channel codes are committed, carrying details about the committed codes and user permissions. These events follow the Prism CompositePresentationEvent pattern for pub/sub messaging within the DTS application.

---

## 2. Public Interface

### `ChannelCodesViewChangedEvent`
**Location:** `DTS.Common.Events` namespace  
**Declaration:**
```csharp
public class ChannelCodesViewChangedEvent : CompositePresentationEvent<DTS.Common.Enums.IsoViewMode> { }
```
**Behavior:** An event class that publishes/subscribes to view mode changes. The payload is a single `DTS.Common.Enums.IsoViewMode` value indicating the new view mode.

---

### `ChannelCodeCommittedEvent`
**Location:** `DTS.Common.Events.ChannelCodes` namespace  
**Declaration:**
```csharp
public class ChannelCodeCommittedEvent : CompositePresentationEvent<ChannelCodeCommittedEventArgs[]> { }
```
**Behavior:** An event class that publishes/subscribes to channel code commit notifications. The payload is an array of `ChannelCodeCommittedEventArgs` objects, allowing multiple codes to be committed in a single event.
