Documentation: Template Channel List Events

1. Purpose

This module defines three Prism event types for broadcasting changes related to template channel lists within the group templates subsystem. These events enable loosely-coupled communication between components when channel order changes, selection state changes, or required channel state changes occur. All events follow the Prism Event Aggregator pattern, extending PubSubEvent<T>.

---

2. Public Interface

TemplateChannelListOrderChangedEvent

Signature: public class TemplateChannelListOrderChangedEvent : PubSubEvent<IGroupTemplateChannel>

An event that publishes IGroupTemplateChannel payloads when the order of channels in a template channel list has changed.

---

TemplateChannelListSelectionChangedEvent

Signature: public class TemplateChannelListSelectionChangedEvent : PubSubEvent<IGroupTemplateChannel>

An event that publishes IGroupTemplateChannel payloads when the selection state within a template channel list has changed.

---

TemplateChannelListRequiredChangedEvent

Signature: public class TemplateChannelListRequiredChangedEvent : PubSubEvent<TemplateChannelListRequiredChangeEventArgs>

An event that publishes TemplateChannelListRequiredChangeEventArgs payloads when the "required" state of template channels has changed.

---

TemplateChannelListRequiredChangeEventArgs

Signature: public class TemplateChannelListRequiredChangeEventArgs

A payload class carrying information about required channel changes.

Property	Type	Description
Consumer	object	The consumer object associated with the change.
Channels	IGroupTemplateChannel[]	Array of channels affected by the required change.

Constructor:

public TemplateChannelListRequiredChangeEventArgs(object o, IGroupTemplateChannel[] channels)

---

3. Invariants

• All three event classes inherit from PubSubEvent<T> from Prism, ensuring they work with the Prism Event Aggregator pattern.
• TemplateChannelListOrderChangedEvent and TemplateChannelListSelectionChangedEvent both use IGroupTemplateChannel as their payload type.
• TemplateChannelListRequiredChangedEvent uses TemplateChannelListRequiredChangeEventArgs as its payload type, which encapsulates both a consumer reference and an array of channels.
• TemplateChannelListRequiredChangeEventArgs.Channels is an array (not a collection), set at construction time with no null validation in the constructor.

---

4. Dependencies

This module depends on:

• DTS.Common.Interface.GroupTemplate — provides the IGroupTemplateChannel interface used as payload type
• Prism.Events — provides
