# Phase 14 Plan 02: Directory Browse UI Summary

**Full directory browse mode UI with mode toggle RadioButtons, 5-column DataGrid, loading status, guest highlighting, and shared SelectedUsers section**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-09T07:28:21Z
- **Completed:** 2026-04-09T07:30:10Z
- **Tasks:** 1
- **Files modified:** 1

## Accomplishments
- Mode toggle (Search/Browse Directory) RadioButtons at top of left panel with InverseBoolConverter binding
- Search panel collapses when IsBrowseMode=true via DataTrigger approach; Browse panel shows via BoolToVisibilityConverter
- Directory panel with Load/Cancel buttons, IncludeGuests checkbox, filter TextBox, status/count display
- DataGrid with 5 columns (Name, Email, Department, Job Title, Type) bound to DirectoryUsersView
- Guest users highlighted in orange (#F39C12) with SemiBold font weight via DataTrigger on UserType
- SelectedUsers ItemsControl extracted from search GroupBox to shared section visible in both modes
- Scan Options and Run/Export buttons remain always visible in both modes

## Task Commits

Each task was committed atomically:

1. **Task 1: Restructure left panel with mode toggle and conditional panels** - `1a1e83c` (feat)

## Files Created/Modified
- `SharepointToolbox/Views/Tabs/UserAccessAuditView.xaml` - Added mode toggle, browse panel with DataGrid, extracted SelectedUsers to shared section

## Decisions Made
- Used DataTrigger inverse visibility for search panel (Visible by default, Collapsed when IsBrowseMode=True) instead of ConverterParameter=Inverse -- more reliable across WPF versions
- Used plain English strings for DataGrid column headers ("Name", "Email", "Department", "Job Title", "Type") instead of localized bindings -- DataGridTextColumn.Header does not reliably support binding in standard WPF
- Moved GroupBox.Header to nested TextBlock element for search panel to avoid conflict between inline Header binding and GroupBox.Style on the same element

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Phase 14 is now complete (both plans executed)
- All directory browse UI elements are wired to ViewModel properties from Phase 13
- Manual testing recommended to verify visual layout, mode switching, DataGrid scrolling, and double-click selection
