# Documentation: PedestrianAndHeadReports ViewModels
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
|
||
|
|
This module provides ViewModel implementations for report generation within the DataPRO reporting system. It contains two primary ViewModels: `HeadReportViewModel` for head report functionality (currently limited to XML string handling per source comments), and `TRLReportViewModel` for TRL (Test Research Laboratory) reports that manage test data including acceleration, bending, and shear channel measurements. Both ViewModels follow the MVVM pattern using Microsoft Prism framework, providing input/output view management, event aggregation for cross-component communication, and lifecycle methods for initialization and cleanup.
