Documentation: Report Export Events

1. Purpose

This module defines two Prism event aggregation types for requesting report exports in the DTS Viewer application. SaveReportToCSVRequestedEvent and SaveReportToPDFRequestedEvent enable loosely-coupled communication between view models and report generation services, allowing components to request CSV or PDF exports without direct dependencies on each other. Both events carry the target directory path and a reference to the requesting parent view model.

---

2. Public Interface

SaveReportToCSVRequestedEvent

Signature: public class SaveReportToCSVRequestedEvent : PubSubEvent<SaveReportToCSVRequestedEventArgs>

An event type for publishing and subscribing to CSV export requests. Inherits from Prism's PubSubEvent<T> and uses SaveReportToCSVRequestedEventArgs as its payload type.

---

SaveReportToCSVRequestedEventArgs

Signature: public class SaveReportToCSVRequestedEventArgs

Payload class carrying data for CSV export requests.

Property	Type	Access
Directory	string	get; set;
ParentVM	IBaseViewModel	get; set;

---

SaveReportToPDFRequestedEvent

Signature: public class SaveReportToPDFRequestedEvent : PubSubEvent<SaveReportToPDFRequestedEventArgs>

An event type for publishing and subscribing to PDF export requests. Inherits from Prism's PubSubEvent<T> and uses SaveReportToPDFRequestedEventArgs as its payload type.

---

SaveReportToPDFRequestedEventArgs

Signature: public class SaveReportToPDFRequestedEventArgs

Payload class carrying data for PDF export requests.

Property	Type	Access
Directory	string	get; set;
ParentVM	IBaseViewModel	get; set;

---

3. Invariants

• Both event args classes expose identical property structures (Directory and ParentVM).
• Directory is intended to represent a file system path for the export destination.
• ParentVM must implement IBaseViewModel interface from DTS.Common.Base.
• Properties are mutable (public setters); no constructor-based initialization is enforced.
• No null validation or path validation is performed within these classes.

---

4. Dependencies

This module depends on:

• Prism.Events — Provides PubSubEvent<T> base class for event aggregation
• DTS.Common.Base — Provides IBaseViewModel interface

Consumers (inferred):

• Any module publishing or subscribing to report export requests via Prism's IEventAggregator
• Report generation services that handle these events
• View models that initiate export operations
