# Dependency graph
|
|
requires:
|
|
- phase: 06-global-site-selection/06-01
|
|
provides: GlobalSitesChangedMessage class in Core/Messages
|
|
provides:
|
|
- GlobalSelectedSites ObservableCollection on MainWindowViewModel
|
|
- OpenGlobalSitePickerCommand (disabled when no profile)
|
|
- GlobalSitesSelectedLabel computed property for toolbar
|
|
- WeakReferenceMessenger broadcast on GlobalSelectedSites change
|
|
- Clear on tenant switch and session clear
|
|
affects:
|
|
- 06-03 (toolbar XAML binds to these properties)
|
|
- 06-04 (FeatureViewModelBase registers for GlobalSitesChangedMessage)
|

# Phase 06 Plan 02: MainWindowViewModel Global Site Selection Summary
|
|
|
|
**ObservableCollection<SiteInfo> GlobalSelectedSites with dialog command, computed label, messenger broadcast, and clear-on-tenant-switch added to MainWindowViewModel**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 8 min
|
|
- **Started:** 2026-04-07T10:10:00Z
|
|
- **Completed:** 2026-04-07T10:18:00Z
|
|
- **Tasks:** 1
|
|
- **Files modified:** 1
|
|
|
|
## Accomplishments
|
|
- Added GlobalSelectedSites and OpenGlobalSitePickerCommand to MainWindowViewModel — toolbar UI (06-03) can bind directly
|
|
- WeakReferenceMessenger broadcasts GlobalSitesChangedMessage on every collection change — all tab VMs receive live updates
|
|
- GlobalSelectedSites cleared on tenant switch and session clear, keeping site selection scoped to the current tenant
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Add global site selection state, command, and broadcast to MainWindowViewModel** - `a10f03e` (feat)
|
|
|
|
**Plan metadata:** _(docs commit to follow)_
|
|
|
|
## Files Created/Modified
|
|
- `SharepointToolbox/ViewModels/MainWindowViewModel.cs` - Added OpenGlobalSitePickerDialog factory, GlobalSelectedSites, GlobalSitesSelectedLabel, OpenGlobalSitePickerCommand, ExecuteOpenGlobalSitePicker, BroadcastGlobalSites; clear on tenant switch and session clear
|
|
|
|
## Decisions Made
|
|
- Added `using SharepointToolbox.Views.Dialogs;` to MainWindowViewModel — acceptable because this VM already holds `Func<Window>?` factory properties that reference the View layer. The cast in `ExecuteOpenGlobalSitePicker` requires knowing the concrete dialog type.
|
|
- `GlobalSitesSelectedLabel` uses a hardcoded English string for now; plan 06-03 will replace it with a localized key from Strings.resx once toolbar XAML is added.
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
(Note: `GlobalSitesChangedMessage.cs` was already present from plan 06-01 — no deviation needed.)
|
|
|
|
## Issues Encountered
|
|
None.
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- MainWindowViewModel now exposes all properties and commands needed for the toolbar XAML (plan 06-03)
|
|
- `OpenGlobalSitePickerDialog` factory property ready to be wired in MainWindow.xaml.cs (plan 06-03)
|
|
- GlobalSitesChangedMessage broadcasting is live; FeatureViewModelBase can register for it (plan 06-04)
