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.

2. Public Interface

HeadReportViewModel

Class Signature:

[Export(typeof(IHeadReportInputView))]
[Export(typeof(IHeadReportOutputView))]
[PartCreationPolicy(CreationPolicy.Shared)]
public class HeadReportViewModel : IHeadReportViewModel

Constructor:

public HeadReportViewModel(
    IHeadReportInputView inputView, 
    IHeadReportOutputView outputView, 
    IRegionManager regionManager, 
    IEventAggregator eventAggregator, 
    IUnityContainer unityContainer)

Properties:

Property	Type	Description
InputView	IHeadReportInputView	The input view instance; DataContext is set to this during construction
OutputView	IHeadReportOutputView	The output view instance; DataContext is set to this during construction
NotificationRequest	InteractionRequest<Notification>	Prism interaction request for displaying notifications
ConfirmationRequest	InteractionRequest<Confirmation>	Prism interaction request for displaying confirmations
IsDirty	bool	Indicates whether the view model has unsaved changes; private setter
IsBusy	bool	Controls busy indicator state; raises PropertyChanged on set
IsMenuIncluded	bool	Indicates whether menu is included; raises PropertyChanged on set
IsNavigationIncluded	bool	Indicates whether navigation is included; raises PropertyChanged on set
HeaderInfo	string	Returns constant string "MainRegion"

Methods:

Method	Return Type	Description
