Documentation: TestSummaryList ViewModels

1. Purpose

This module provides two ViewModel implementations (TestSummaryViewModel and TestSummaryViewListModel) for managing and displaying test summary data within the DTS Viewer application. Both classes implement ITestSummaryListViewModel and serve as intermediaries between test summary data models and their associated views, handling user interactions, event aggregation for cross-component communication, data filtering, and sorting. The module exists to support the Prism-based MVVM architecture, coordinating test summary selection, folder/file data loading, and notification publishing to other application components.

2. Public Interface

TestSummaryViewModel

Constructor:

public TestSummaryViewModel(ITestSummaryListView view, IRegionManager regionManager, IEventAggregator eventAggregator, IUnityContainer unityContainer)

Initializes the ViewModel, sets the view's DataContext, creates interaction requests, and subscribes to RaiseNotification and DataFolderChangedEvent events.

Methods:

Method	Signature	Description
Initialize	void Initialize()	Empty override.
Initialize	void Initialize(object parameter)	Casts parameter to IBaseWindowModel and assigns to Parent.
Activated	void Activated()	Throws NotImplementedException.
Cleanup	void Cleanup()	Throws NotImplementedException.
CleanupAsync	Task CleanupAsync()	Throws NotImplementedException.
InitializeAsync	Task InitializeAsync()	Throws NotImplementedException.
InitializeAsync	Task InitializeAsync(object parameter)	Throws NotImplementedException.
PublishSelectedTestSummaryList	void PublishSelectedTestSummaryList()	Publishes TestSummaryChangeNotification and TestSelectedChangedEvent events with current selection.

Properties:

Property	Type	Description
TestSummaryListView	ITestSummaryListView	The associated view instance.
NotificationRequest	InteractionRequest<Notification>	Prism interaction request for notifications.
ConfirmationRequest	InteractionRequest<Confirmation>	Prism interaction request for confirmations.
ContextNavigationRegion	object	Gets/sets content of TestListRegion on the view.
SelectedTestSummary	TestSummary	Currently selected single test summary.
SelectedTestSummaryList	List<ITestSummary>	List of selected test summaries.
TestSummaryList	ObservableCollection<ITestSummary>	Collection of all test summaries.
HeaderInfo	string	Returns "TestSummaryRegion".
IsBusy	bool	Busy indicator state.
IsDirty	bool	Dirty state flag.
IsNavigationIncluded	bool	Navigation inclusion flag.

Events:

• PropertyChanged - Custom PropertyChangedEventHandler (hides base implementation with new).

TestSummaryViewListModel

Constructor:

public TestSummaryViewListModel(ITestSummaryListView view, IRegionManager regionManager, IEventAggregator eventAggregator, IUnityContainer unityContainer)

Initializes the ViewModel, sets the view's DataContext, creates interaction requests, and stores dependencies.

Methods:

Method	Signature	Description
Initialize	void Initialize()	Empty override.
Initialize	void Initialize(object parameter)	Sets Parent, initializes FilterView, attaches collection changed handlers, and calls Subscribe().
OnFilterChanged	void OnFilterChanged(FilterParameterArgs args)	Filters FilteredTestSummaryList based on SetupName, Id, or Description containing the parameter string.
Activated	void Activated()	Publishes empty FilterParameterChangedEvent to reset filter.
Cleanup	void Cleanup()	Clears all collections, resets SelectedTestSummary, and publishes selection changes.
PublishSelectedTestSummaryList	void PublishSelectedTestSummaryList()	Publishes TestSummaryChangeNotification, TestSummaryCountNotification, and ResetZoomChangedEvent.
RefreshDataFolder	void RefreshDataFolder()	Publishes DataFolderChangedEvent via dispatcher.
SelectDataFolder	void SelectDataFolder()	Opens OpenFileDialog for .dts files and publishes DataFileSelectedEvent.
SortTestSummaryList	void SortTestSummaryList()	Sorts FilteredTestSummaryList based on SelectedSortIndex.

Properties:

Property	Type	Description
FilterView	IFilterView	Resolved filter view instance.
View	ITestSummaryListView	The associated view instance.
NotificationRequest	InteractionRequest<Notification>	Prism interaction request for notifications.
ConfirmationRequest	InteractionRequest<Confirmation>	Prism interaction request for confirmations.
ContextNavigationRegion	object	Gets/sets DataContext of TestListRegion on the view.
IsFilterEnabled	bool	Indicates if filtering is available (true when list has items).
SelectedTestSummary	TestSummary	Currently selected single test summary.
SelectedTestSummaryList	List<ITestSummary>	List of selected test summaries.
TestSummaryList	ObservableCollection<ITestSummary>	Full collection; setter updates IsFilterEnabled and FilteredTestSummaryList.
FilteredTestSummaryList	ObservableCollection<ITestSummary>	Filtered/sorted view of test summaries.
HeaderInfo	string	Returns "TestSummaryRegion".
IsBusy	bool	Busy indicator state.
IsDirty	bool	Dirty state flag.
IsNavigationIncluded	bool	Navigation inclusion flag.
SelectedDataFolder	string	Selected folder path; setter publishes DataFolderChangedEvent.
SelectedDataFile	string	Selected file path; setter publishes DataFolderChangedEvent.
SortableAttributes	List<string>	Localized list of sortable attribute names.
SelectedSortIndex	int	Index of selected sort; setter triggers SortTestSummaryList().
