Phase 03 Plan 07: StorageViewModel + StorageView XAML + DI Wiring Summary

StorageViewModel orchestrating IStorageService via FeatureViewModelBase + StorageView DataGrid with IndentConverter-based tree indentation, fully wired through DI in MainWindow

Performance

• Duration: ~4 min
• Started: 2026-04-02T13:35:02Z
• Completed: 2026-04-02T13:39:00Z
• Tasks: 2
• Files modified: 10

Accomplishments

• StorageViewModel created with RunOperationAsync → IStorageService.CollectStorageAsync, FlattenNode tree-flattening, Dispatcher.InvokeAsync-safe ObservableCollection update
• StorageView.xaml DataGrid with IndentLevel-driven Thickness margin, BytesConverter for human-readable sizes, all scan/export controls bound to ViewModel
• IndentConverter, BytesConverter, InverseBoolConverter, and RightAlignStyle registered in App.xaml Application.Resources
• Storage tab live in MainWindow via DI-resolved StorageView (same pattern as Permissions tab)

Task Commits

Each task was committed atomically:

1. Task 1: Create StorageViewModel - e174a18 (feat)
2. Task 2: Create StorageView XAML + code-behind, update DI and MainWindow wiring - e08452d (feat)

Files Created/Modified

• SharepointToolbox/ViewModels/Tabs/StorageViewModel.cs - Storage tab ViewModel (IStorageService orchestration, export commands, tenant-switching)
• SharepointToolbox/Views/Tabs/StorageView.xaml - Storage tab XAML (DataGrid + scan controls + export buttons)
• SharepointToolbox/Views/Tabs/StorageView.xaml.cs - Code-behind wiring DataContext to StorageViewModel
• SharepointToolbox/Views/Converters/IndentConverter.cs - IndentConverter, BytesConverter, InverseBoolConverter in one file
• SharepointToolbox/App.xaml - Registered three converters and RightAlignStyle in Application.Resources
• SharepointToolbox/App.xaml.cs - Phase 3 Storage DI registrations (IStorageService, exports, VM, View)
• SharepointToolbox/MainWindow.xaml - Added x:Name=StorageTabItem to Storage TabItem
• SharepointToolbox/MainWindow.xaml.cs - Wired StorageTabItem.Content from DI
• SharepointToolbox/Services/Export/SearchCsvExportService.cs - Added missing System.IO using
• SharepointToolbox/Services/Export/SearchHtmlExportService.cs - Added missing System.IO using

Decisions Made

• ClientContext.Url is read-only in CSOM — the site URL override is done by creating a new TenantProfile with TenantUrl = SiteUrl (same ClientId/Name from current profile), passed to GetOrCreateContextAsync.
• All three converters (IndentConverter, BytesConverter, InverseBoolConverter) registered at Application scope in App.xaml rather than per-view, avoiding duplicate resource key definitions.
• StorageView.xaml omits local UserControl.Resources declarations for converters — references Application-level StaticResource instead, keeping the XAML clean.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed ClientContext.Url read-only assignment in StorageViewModel.RunOperationAsync

• Found during: Task 1 (StorageViewModel creation)
• Issue: Plan included ctx.Url = SiteUrl.TrimEnd('/') but ClientRuntimeContext.Url is a read-only property in CSOM
• Fix: Created a new TenantProfile{TenantUrl=siteUrl, ClientId, Name} and passed it to GetOrCreateContextAsync — the context is keyed by URL so it gets or creates the right session
• Files modified: SharepointToolbox/ViewModels/Tabs/StorageViewModel.cs
• Verification: Build succeeded with 0 errors
• Committed in: e174a18 (Task 1 commit)

2. [Rule 3 - Blocking] Added missing System.IO using to SearchCsvExportService and SearchHtmlExportService

• Found during: Task 1 build verification
• Issue: Both Search export services used File.WriteAllTextAsync without using System.IO; — same established project convention (WPF project does not include System.IO in implicit usings)
• Fix: Added using System.IO; to both files
• Files modified: SharepointToolbox/Services/Export/SearchCsvExportService.cs, SharepointToolbox/Services/Export/SearchHtmlExportService.cs
• Verification: Build succeeded with 0 errors; 82 tests pass
• Committed in: e174a18 (Task 1 commit)

---

Total deviations: 2 auto-fixed (1 bug, 1 blocking) Impact on plan: Both auto-fixes necessary for correctness. No scope creep.

Issues Encountered

None beyond the two auto-fixed deviations above.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• StorageView is live and functional — users can enter site URL, configure scan options, run scan, and export results
• Plans 03-03 (StorageCsvExportService) and 03-06 (localization keys) are prerequisites and were already completed
• Ready for Wave 4: Plan 03-08 (SearchViewModel + DuplicatesViewModel + Views + visual checkpoint)
• All 82 tests passing, 10 expected skips (CSOM live-connection tests)
