# Classes
### Purpose
This module provides UI helper classes for the DTS Viewer WPF application. It includes a `BindingProxy` for enabling data binding in contexts where the data context is not directly accessible (e.g., within style setters), and a `ComponentsGroupControl` custom control for displaying grouped UI components with an image and title. Several placeholder classes (`MenuItem`, `TabItem`, `NavigationItem`) exist but contain no implementation.
### Public Interface
**BindingProxy** (inherits `Freezable`)
- `protected override Freezable CreateInstanceCore()` - Creates a new instance of `BindingProxy`. Required override for `Freezable` inheritance.
- `public static readonly DependencyProperty DataProperty` - Dependency property identifier for `Data`.
- `public object Data { get; set; }` - Gets or sets the data object to proxy for binding purposes.
**ComponentsGroupControl** (inherits `Control`)
- `public class ClickEventArgs : EventArgs` - Nested event args class with default constructor.
- `public static RoutedCommand ClickCommand { get; }` - Static routed command for click handling.
- `public static readonly DependencyProperty ImageProperty` - Dependency property identifier for `Image`.
- `public ImageSource Image { get; set; }` - Gets or sets the image source for the control.
- `public static readonly DependencyProperty TitleProperty` - Dependency property identifier for `Title`.
- `public string Title { get; set; }` - Gets or sets the title text; default value is "Title".
**MenuItem**
- No public members defined (empty class).
**TabItem**
- No public members defined (empty class).
**NavigationItem**
- No public members defined (empty class).
### Invariants
- `BindingProxy` must inherit from `Freezable` to participate in the WPF property system and support data binding in style setters.
- `ComponentsGroupControl` registers a default style key via `DefaultStyleKeyProperty.OverrideMetadata` in its static constructor, implying a XAML style/template must exist elsewhere.
- `ComponentsGroupControl.ClickCommand` is registered at the class level via `CommandManager.RegisterClassCommandBinding`.
### Dependencies
- **Depends on**: `System.Windows`, `System.Windows.Controls`, `System.Windows.Input`, `System.Windows.Media`.
- **Depended on by**: Unclear from source alone; likely used in DTS Viewer views and XAML templates.
### Gotchas
- **Commented-out code**: `ComponentsGroupControl` contains commented

# Documentation: DTS.Viewer Main View Components
## 1. Purpose
This module contains the main view components for the DTS Viewer application, implementing a WPF-based visualization and export system. It provides multiple view variants (standard, lite, export, and viewer modes) that serve as UI shells for chart/graph visualization and PDF export functionality. The views follow a code-behind pattern with XAML partial classes, integrating with Prism's event aggregation system for loosely-coupled communication between components.
---
## 2. Public Interface

# DTS Viewer Main Module ViewModels Documentation
## 1. Purpose
This module contains the core ViewModel layer for the DTS Viewer application's main shell and content regions. It implements the MVVM pattern using Microsoft Prism and Unity IoC, providing three primary ViewModels: `ViewerShellViewModel` serves as the application shell container, `MainViewModel` manages the primary viewer interface with multiple regions (navigation, graph, property panels), and `ExportMainViewModel` extends functionality for data export operations including PDF generation and layout persistence. The module orchestrates view composition through region management and pub/sub event aggregation for loosely-coupled inter-component communication.

## 3. Invariants
1. **MEF Singleton Shell**: `ViewerShellViewModel` is exported with `CreationPolicy.Shared`, ensuring a single shell instance per application.
2. **Region Naming Convention**: All regions are accessed via properties named `Context*Region` and are retrieved from view controls with corresponding `*Region` property names.
3. **Event Subscription Pattern**: All ViewModels subscribe to events in their constructors or `Initialize` methods; no unsubscription logic is visible in the source.
4. **Parent-Child Relationship**: `MainViewModel` and `ExportMainViewModel` expect `Initialize(object parameter)` to receive an `IBaseWindowModel` castable object.
5. **Standalone Mode Switching**: `ExportMainViewModel` region accessors must check `Standalone` boolean to determine correct view type (`ExportMainView` vs `ExportMainViewGrid`).
6. **Busy Indicator Pairing**: `IsBusy` and `IsBusyMessage` are intended to be used together for UI feedback during operations.
7. **Layout File Dependencies**: `LoadLayoutCommand` requires `.\DataProViewerAvalonDock.config` to exist; `SaveLayoutCommand` writes to `.\AvalonDock.config`.

# Properties
### 1. Purpose
This module contains the assembly-level configuration and auto-generated code for the `DTS.Viewer` assembly. It defines the application's identity, version information, and provides strongly-typed access to application settings and localized resources via the `Properties` namespace. It serves as the configuration backbone for the DTS Viewer application.
### 2. Public Interface
**Class: `Settings`** (in `Settings.Designer.cs`)
* `public static Settings Default { get; }`: Provides access to the singleton instance of the application settings wrapper.
**Class: `Resources`** (in `Resources.Designer.cs`)
* `internal static global::System.Resources.ResourceManager ResourceManager { get; }`: Returns the cached resource manager instance used for looking up localized strings.
* `internal static global::System.Globalization.CultureInfo Culture { get; set; }`: Gets or sets the current UI culture for resource lookups.
**Assembly Attributes** (in `AssemblyInfo.cs`)
* `AssemblyTitle`: "DTS.Viewer"
* `AssemblyCompany`: "Diversified Technical Systems, Inc. (DTS)"
* `AssemblyVersion`: "1.0.0.0"
* `AssemblyFileVersion`: "1.0.0.0"
### 3. Invariants
* The `Settings` class is a sealed, singleton wrapper inheriting from `ApplicationSettingsBase`.
* The `Resources` class is auto-generated and intended for internal access only (`internal` class).
* Files `Settings.Designer.cs` and `Resources.Designer.cs` are marked with `GeneratedCodeAttribute`; manual changes will be overwritten by tooling.
### 4. Dependencies
* **Depends on**: `System.Configuration` (for `ApplicationSettingsBase`), `System.Resources` (for `ResourceManager`), `System.Runtime.CompilerServices`, `System.CodeDom.Compiler`.
* **Depended on by**: The main `DTS.Viewer` application logic (for accessing settings and resources).
### 5. Gotchas
* None identified from source alone, other than the standard warning that designer files should not be manually edited.

# RegionAdapters
### Purpose
This module provides a custom Prism Region Adapter for `StackPanel` controls, enabling the Prism region management system to dynamically add and remove UI elements within a `StackPanel`. It bridges the gap between Prism's region architecture and WPF's `StackPanel` container, allowing views to be composed dynamically at runtime.
### Public Interface
- **`StackPanelRegionAdapter(IRegionBehaviorFactory regionBehaviorFactory)`** (Constructor)
- Initializes the adapter with the specified `IRegionBehaviorFactory`. Required by the base `RegionAdapterBase<StackPanel>`.
- **`protected override void Adapt(IRegion region, StackPanel regionTarget)`**
- Subscribes to the `region.Views.CollectionChanged` event and synchronizes the `StackPanel.Children` collection with the region's views. Handles `NotifyCollection

# Resources
### Purpose
This module provides localization infrastructure for the DTS Viewer application. It contains a WPF markup extension for XAML binding to localized strings and an auto-generated strongly-typed resource class that wraps access to the underlying `.resx` resource file.
### Public Interface
**`TranslateExtension` (class)**
- Inherits: `MarkupExtension`
- Attribute: `[MarkupExtensionReturnType(typeof(string))]`
- Constructor: `TranslateExtension(string key)` — Stores the resource key for lookup.
- `object ProvideValue(IServiceProvider serviceProvider)` — Returns the localized string for the stored `_key`. Returns `#stringnotfound#` if the key is null/empty, or `#stringnotfound# {key}` if the lookup fails.
**`StringResources` (class)**
- Attribute: `internal`
- `static ResourceManager ResourceManager` — Gets the cached `ResourceManager` instance for this assembly.
- `static CultureInfo Culture` — Gets or sets the current UI culture for resource lookups.
- **Resource String Properties (static getters):**
- `string ChartOptionsHeader` — Localized string "Chart Options".
- `string GraphsDefaultTitle` — Localized string "Graphs ".
- `string ModificationsHeader` — Localized string "Modify".
- `string SavePDFError` — Localized string "Error occurred saving chart to PDF".
- `string SavePDFSuccess` — Localized string "Chart saved succesfully as {0}{1} and {2}{3}".
- `string SettingsTitle` — Localized string "Settings".
- `string TestIDsDefaultTitle` — Localized string "Test IDs".
- `string TestsDefaultTitle` — Localized string "Tests ".

# View
### Purpose
This module provides WPF view components for the DTS Viewer application. It contains code-behind files for various XAML views that implement interfaces from `DTS.Common.Interface`, following a view-first architecture where each view is a partial class paired with XAML markup. The views serve as passive containers with no logic beyond initialization.
### Public Interface
**TabView** : `ITabView`
- `TabView()` - Default constructor that calls `InitializeComponent()` to load the associated XAML.
**MenuView** : `IMenuView`
- `MenuView()` - Default constructor that calls `InitializeComponent()` to load the associated XAML.
**MainView** : `IMainView`
- `MainView()` - Default constructor that calls `InitializeComponent()` to load the associated XAML.
**ShellView** : `IViewerShellView`
- `ShellView()` - Default constructor that calls `InitializeComponent()` to load the associated XAML.
**ViewerShellView** : `IViewerShellView`
- `ViewerShellView()` - Default constructor that calls `InitializeComponent()` to load the associated XAML.
**NavigationView** : `INavigationView`
- `NavigationView()` - Default constructor that calls `InitializeComponent()` to load the associated XAML.
### Invariants
- Each view must have a corresponding XAML file (e.g., `TabView.xaml`) that defines the UI layout.
- All views implement their respective interfaces from `DTS.Common.Interface`.
- `ShellView` and `ViewerShellView` both implement `IViewerShellView` - unclear if they are intended to be interchangeable or serve different contexts.
### Dependencies
- **Depends on**: `DTS.Common.Interface` (for `ITabView`, `IMenuView`, `IMainView`, `IViewerShellView`, `INavigationView` interfaces)
- **Depended on by**: Not determinable from source alone; likely consumed by a bootstrapper or DI container configuration.
### Gotchas
- **Duplicate shell view implementations**: Both `ShellView` and `ViewerShellView` implement `IViewerShellView`. The source does not clarify which is canonical or under what circumstances each is used. They exist in different namespaces (`DTS.Viewer.View` vs `DTS.Viewer`).
- No view logic beyond initialization is present; any behavior must be implemented in associated ViewModels or elsewhere.

# View
### Purpose
This module provides the code-behind for the `AddCalculatedChannelView` XAML view, serving as the UI component for adding calculated channels within the DTS Viewer application. It implements the `IAddCalculatedChannelView` interface to integrate with the application's view abstraction layer, enabling loose coupling between the view and its consuming components.
### Public Interface
- **`AddCalculatedChannelView()`** (Constructor)
- Initializes the component by calling `InitializeComponent()`. No additional parameters or logic.
- **`IAddCalculatedChannelView`** (Implemented Interface)
- The class implements this interface from `DTS.Common.Interface`, making it usable wherever the interface type is required.
### Invariants
- The view must be a partial class to support WPF's code-generation model for XAML.
- `InitializeComponent()` must be called exactly once during construction to load the associated XAML.
### Dependencies
- **Depends on:** `DTS.Common.Interface` (for `IAddCalculatedChannelView` interface)
- **Depended on by:** Cannot be determined from source alone (likely consumed by a presenter/viewmodel or region navigation in the broader application)
### Gotchas
- The file includes a ReSharper directive `// ReSharper disable CheckNamespace`, suggesting the namespace `DTS.Viewer.AddCalculatedChannel` may not match the project's default namespace structure. This could cause confusion during refactoring or when locating the view.

This module provides the `DockPanelHorizontalViewModel` class, a Prism-based ViewModel for a horizontal dock panel UI component in the DTS Viewer application. It serves as a mediator between the view (`IDockPanelHorizontalView`) and the application infrastructure, handling notification requests via Prism's `InteractionRequest` pattern and subscribing to application-wide `RaiseNotification` events.
### Public Interface
**Class:** `DockPanelHorizontalViewModel` (extends `BaseViewModel<IDockPanelHorizontalViewModel>`, implements `IDockPanelHorizontalViewModel`)
**Constructor:**
```csharp
public DockPanelHorizontalViewModel(
IDockPanelHorizontalView view,
IRegionManager regionManager,
IEventAggregator eventAggregator,
IUnityContainer unityContainer)
```
Initializes the ViewModel, sets the View's DataContext to itself, creates `NotificationRequest` and `ConfirmationRequest` instances, and subscribes to the `RaiseNotification` event.
**Properties:**
- `IDockPanelHorizontalView View { get; }` — The associated view instance.
- `InteractionRequest<Notification> NotificationRequest { get; }` — Used to raise notification dialogs.
- `InteractionRequest<Confirmation> ConfirmationRequest { get; }` — Used to raise confirmation dialogs.
- `bool IsMenuIncluded { get; set; }` — UI state flag.
- `bool IsNavigationIncluded { get; set; }` — UI state flag.
- `bool IsBusy { get; set; }` — Indicates busy state.
- `bool IsDirty { get; private set; }` — Indicates unsaved changes.
**Events:**
- `event PropertyChangedEventHandler PropertyChanged` — Declared but not explicitly invoked in visible code.
**Methods:**
- `void OnRaiseNotification(NotificationContentEventArgs eventArgsWithTitle)` — Private handler that raises `NotificationRequest` with title, message, details, and image from the event args.
- `override void Initialize()` — Throws `NotImplementedException`.
- `override void Initialize(object parameter)` — Throws `NotImplementedException`.
- `void Initialize(object parameter, object model)` — Throws `NotImplementedException` (hides base with `new`).
- `override void Activated()` — Throws `NotImplementedException`.
- `override void Cleanup()` — Throws `NotImplementedException`.
- `Task CleanupAsync()` — Throws `NotImplementedException` (hides base with `new`).
- `override Task InitializeAsync()` — Throws `NotImplementedException`.
- `override Task InitializeAsync(object parameter)` — Throws `NotImplementedException`.
### Invariants
- The View's `DataContext` is always set to the ViewModel instance upon construction.
- The ViewModel subscribes to `RaiseNotification` event via `EventAggregator` on construction.
- `IsDirty` is read-only externally (private setter).
### Dependencies
**Depends on:**
- `DTS.Common.Base` (`BaseViewModel<T>`)
- `DTS.Common.Events` (`RaiseNotification`, `NotificationContentEventArgs`, `NotificationContentEventArgsWithoutTitle` — inferred from usage)
- `DTS.Common.Interface` (`IViewModel`, `IDockPanelHorizontalViewModel`, `IDockPanelHorizontalView`)
- `Microsoft.Practices.Prism.Events` (`IEventAggregator

# View
### Purpose
The `NavigationViewModel` class serves as the ViewModel component for the navigation region in a Prism-based WPF application. It manages the `ContextNavigationRegion` content area, handles notification display via event aggregation, and coordinates with a parent `IShellViewModel`. This module exists to decouple navigation logic from the view while providing notification capabilities through the Prism InteractionRequest pattern.
### Public Interface
**Constructor**
- `NavigationViewModel(INavigationView view, IRegionManager regionManager, IEventAggregator eventAggregator, IUnityContainer unityContainer)` — Initializes the view model, sets the view's DataContext, creates `NotificationRequest` and `ConfirmationRequest` interaction requests, and subscribes to the `RaiseNotification` event.
**Properties**
- `INavigationView NavigationView { get; }` — Returns the associated navigation view instance.
- `InteractionRequest<Notification> NotificationRequest { get; }` — Interaction request for displaying notifications.
- `InteractionRequest<Confirmation> ConfirmationRequest { get; }` — Interaction request for displaying confirmations.
- `object ContextNavigationRegion { get; set; }` — Gets or sets the content of the `NavigationRegion` from the underlying `NavigationView`. Raises `OnPropertyChanged` on set.
- `string HeaderInfo { get; }` — Always returns `"NavigationRegion"`.
- `bool IsBusy { get; set; }` — Throws `NotImplementedException` on both getter and setter.
- `bool IsDirty { get;

# DTS.Viewer ViewModel Module Documentation
## 1. Purpose
This module provides the core ViewModel layer for the DTS Viewer WPF application, implementing the MVVM pattern with Prism framework integration. It contains the shell-level view models (`ShellViewModel`, `ViewerShellViewModel`), navigation components (`NavigationViewModel`), menu handling (`MenuViewModel`), and main content orchestration (`MainViewModel`). These ViewModels manage view lifecycle, region navigation, event aggregation for decoupled communication, and dependency injection registration for their associated views.

## 3. Invariants
1. **Constructor Initialization Order:** All view models set `View.DataContext = this` in the constructor before any other initialization.
2. **Event Subscription Pattern:** All view models subscribe to `RaiseNotification` event via `EventAggregator.GetEvent<RaiseNotification>().Subscribe(OnRaiseNotification)` in the constructor.
3. **Notification Transformation:** `OnRaiseNotification` handlers always transform `NotificationContentEventArgs` to a new instance containing only `Message`, `MessageDetails`, and `Image` (excluding `Title` from content object, passing it separately to `Notification.Title`).
4. **Parent Assignment:** `Initialize(object parameter)` expects `parameter` to be castable to the appropriate parent interface (`IShellViewModel` or `IViewerShellViewModel`).
5. **MEF Export:** `ShellViewModel` and `ViewerShellViewModel` are exported as `IShellView` with `CreationPolicy.Shared`.
6. **Unity Registration Timing:** Type registrations (`RegisterType`) occur in constructors, meaning they execute before any view model methods.
