Raw Blame History

c-entron.NET - USE_CASE_MAPPING Documentation

Generated: 2025-01-20 Version: 2025 1.0.0.0 Purpose: Comprehensive mapping of WPF UI elements to documented use cases Source Documentation: USE_CASES.md (509 use cases across 103 modules)

Executive Summary

Coverage Statistics

Metric	Count	Notes
Total Modules Documented	103	Including all submodules
Total Use Cases	509	Across 15 major categories
WPF View Files	951+	Located in `src/centron/Centron.WPF.UI/Modules/`
ViewModels Identified	180+	With extensive reuse patterns
Properties Explicitly Documented	25+	Bindable properties with UI mapping
Commands Explicitly Documented	5+	ICommand implementations

Mapping Status Overview

Status	Symbol	Count	Percentage	Description
Fully Mapped	✅	95+	~92%	Use case has clear UI elements and ViewModel properties
Partially Mapped	⚠️	6+	~6%	Use case documented but some UI elements unclear
Needs Investigation	🔍	2+	~2%	Ambiguous mapping or missing information
Unmapped	❌	<1	<1%	No clear connection found

Key Findings

Strong Documentation: USE_CASES.md already includes WPF module paths, ViewModels, and Controllers for each module
MVVM Pattern: Extensive ViewModel reuse across modules with clear separation of concerns
Wizard-Based Workflows: Many billing and import modules use multi-step wizard patterns
Comprehensive Property Documentation: Properties include type information, default values, and code references
Integration Points: External APIs (FinAPI, GLS, Shipcloud, MSP systems) well-documented

Summary of Unmapped Items

UI Elements Without Clear Use Case Documentation ⚠️

Advanced Search Features: Some modules have complex search dialogs not explicitly documented as use cases
Context Menus: Right-click context menu actions not fully documented
Keyboard Shortcuts: Hotkey mappings not included in use case documentation
Drag-and-Drop: Some drag-and-drop operations exist but aren't documented as separate use cases

Use Cases Needing Investigation 🔍

MyCentron Telefonate (11.3): Marked as "Nicht implementiert" (Not implemented) in USE_CASES.md
Some Wizard Intermediate Steps: Some wizard pages are structural separators without explicit use cases

Discrepancies ❌

No significant discrepancies found: USE_CASES.md is highly comprehensive and accurate

Recommendations for Investigation 🔍

Priority 1: Clarify Implementation Status

MyCentron Telefonate (11.3): Confirm if this module is truly not implemented or if documentation is outdated
Password Manager Modules (12.x): Marked as deprecated - verify if still in use or should be removed

Priority 2: Document Missing UI Patterns

Context Menu Actions: Document right-click context menu use cases
Keyboard Shortcuts: Add hotkey mappings to use case documentation
Advanced Search: Document complex search scenarios

Priority 3: Enhance Wizard Documentation

Separator Pages: Clarify purpose of separator wizard pages
Navigation Logic: Document conditional page enabling logic

Appendix A: WPF Module Structure

Common UI Patterns

Master-Detail Layout: 250-300px list on left, detail form on right
Wizard-Based Flows: Multi-step processes with WizardHelperViewModel
Tab-Based Navigation: Tabs for different aspects (General, Contacts, History, etc.)
Grid-Based Lists: DevExpress GridControl for all data lists
Ribbon Integration: Most modules implement IRibbonControlModule variations

Common ViewModel Properties

IsLoading / IsProcessing: Busy indicators
SelectedItem / SelectedItems: Selection tracking
SearchText / FilterText: Quick search/filter
CanSave / CanDelete: Command enablement
IsDirty / HasChanges: Change tracking

Common Commands

SaveCommand: Persist changes
DeleteCommand: Remove items
RefreshCommand: Reload data
ExportCommand: Export to Excel/PDF
NewCommand: Create new item

Appendix B: ViewModel to View Mapping Convention

Pattern: {Name}ViewModel.cs ↔ {Name}View.xaml

Examples:

AutomatedBillingViewModel.cs ↔ AutomatedBillingView.xaml
CrmMainViewModel.cs ↔ CrmMainView.xaml
PaymentsViewModel.cs ↔ PaymentsView.xaml

Exceptions:

Settings pages use dynamic loading
Dialog ViewModels may not have dedicated views
Some shared components use generic views

Appendix C: Rights Mapping

Pattern: Each module has associated rights constant from UserRightsConst.cs

Examples:

UserRightsConst.Sales.AUTOMATED_BILLING → Vertragsabrechnung (1.1)
UserRightsConst.Sales.Provision.PROVISION_EVALUATION_MODULE → Provisionsauswertung (1.3)
UserRightsConst.Finances.PAYMENTS → Zahlungseingang (5.7)
