# Documentation: NavigationView

## 1. Purpose
This module defines the code-behind class for the `NavigationView` component within the DTS Viewer application. It serves as a WPF User Control responsible for the visual presentation of navigation elements. Its primary role is to implement the `INavigationView` interface, bridging the gap between the XAML layout definition and the application's navigation logic.

## 2. Public Interface

### Class: `NavigationView`
**Inherits:** `INavigationView` (from `DTS.Common.Interface`)
**Type:** `partial` class

#### Constructor: `NavigationView()`
*   **Signature:** `public NavigationView()`
*   **Behavior:** Initializes the component. It calls the standard WPF `InitializeComponent()` method, which loads the associated XAML markup (`NavigationView.xaml`) required to render the view.

## 3. Invariants
*   **WPF Initialization:** The `InitializeComponent()` method must be called exactly once upon instantiation to ensure the UI elements defined in XAML are created.
*   **Interface Compliance:** As this class implements `INavigationView`, it must satisfy the contract defined in `DTS.Common.Interface.INavigationView`. (Note: The specific members of this interface are not visible in the provided source).

## 4. Dependencies
*   **Imports:**
    *   `DTS.Common.Interface`: Used for the `INavigationView` interface.
*   **Internal Dependencies:**
    *   `NavigationView.xaml`: This is a code-beind file; it relies on a corresponding XAML file to define the actual UI structure.
    *   Implicit WPF Assemblies: Relies on `System.Windows` (specifically `System.Windows.Controls.UserControl` behavior) for `InitializeComponent()`.

## 5. Gotchas
*   **Missing Logic Implementation:** The source file contains no explicit implementation of the `INavigationView` interface members. It is unclear from this source alone whether the interface is a marker interface (empty) or if the implementation is expected elsewhere (e.g., via explicit interface implementation not shown, or if the file provided is incomplete).
*   **XAML Dependency:** The functionality and visual behavior of this view are entirely dependent on the associated `NavigationView.xaml` file, which is not included here. The C# code acts purely as a bridge.
