UI Architecture

Overview​

The UI layer of MiniMrpOrderCreation implements WPF with MVVM pattern, providing a rich desktop experience for inventory management and purchase order creation. The architecture emphasizes separation of concerns, data binding, and responsive user interfaces.

Technology Stack​

  • WPF: Windows Presentation Foundation for rich UI
  • MVVM: Model-View-ViewModel pattern
  • Data Binding: Two-way binding for reactive UI
  • XAML: Declarative UI definition
  • Material Design: Modern UI components

Component Hierarchy​

MainWindow ├── MainView (Container) ├── WarehouseOrderingView (Primary workflow) ├── InvOrderingCompletionView (Results) └── Dialog Views ├── SupplierSelectionView ├── SalesOrderAllocationsView └── WipAllocationsView

Key Implementation Patterns​

  • View-First approach with dependency injection
  • DataContext binding for ViewModels
  • Command pattern for user actions
  • Event aggregation for cross-component communication
  • Resource dictionaries for styling

Best Practices​

  • Keep views thin, logic in ViewModels
  • Use data templates for complex types
  • Implement INotifyPropertyChanged properly
  • Handle UI thread marshalling
  • Dispose resources in Unloaded events
