View

Purpose

This module contains the code-behind for the HamburgerMenuView WPF UserControl. It provides the UI interaction logic for a hamburger-style menu, specifically handling the click event on the hamburger button to display a context menu retrieved from the view model.

Public Interface

HamburgerMenuView class - Partial class, implements IHamburgerMenuView

• HamburgerMenuView() - Default constructor. Calls InitializeComponent() to load the XAML.
• void Hamburger_Click(object sender, System.Windows.RoutedEventArgs e) - Private event handler. Retrieves the IHamburgerMenuViewModel from DataContext, gets the context menu via GetContextMenu(), sets the PlacementTarget to the sender button, and opens the context menu.

Invariants

• DataContext must be castable to IHamburgerMenuViewModel when Hamburger_Click is invoked, otherwise an InvalidCastException will occur.
• The sender in Hamburger_Click must be castable to Button, otherwise PlacementTarget will be set to null.

Dependencies

• Depends on: DTS.Common.Interface.Menu.HamburgerMenu (for IHamburgerMenuView and IHamburgerMenuViewModel)
• Depends on: System.Windows.Controls (for Button and UserControl base class)
• XAML file: HamburgerMenuView.xaml (referenced via InitializeComponent())

Gotchas

• The file contains a large block of commented-out code (approximately 60 lines) related to GridViewColumnHeader, ListView mouse handling, and SLICE6TreeViewPopup. This appears to be dead code from another view that was copied or refactored. It should be removed for clarity.
• The namespace is declared as HamburgerMenu despite the file path suggesting HamburgerMenu.View, with a // ReSharper disable CheckNamespace directive suppressing the mismatch.
