It would be very helpful if you could test the resulting artifacts from this PR and let us know in a comment if this change resolves your issue. Thank you!

Issue Details

When a CollectionView's IsGrouped property is set to true, the values of FirstVisibleItemIndex, CenterItemIndex, and LastVisibleItemIndex in the ItemsViewScrolledEventArgs passed to the Scrolled event handler are incorrect.

Root Cause

Visible items were sorted only by Row, which produced incorrect ordering when items from multiple sections were visible simultaneously.

Description of Change

iOS (ItemsViewDelegator.cs and ItemsViewDelegator2.cs)

Changed the sort from .OrderBy(x => x.Row) to .OrderBy(x => x.Section).ThenBy(x => x.Row) so that IndexPathsForVisibleItems is ordered correctly across section boundaries. The fix is applied to both the legacy handler (Items/) and the current handler (Items2/).

Issues Fixed

Fixes #17664

Pull request overview

Fixes incorrect ItemsViewScrolledEventArgs visible-item indices for grouped CollectionView on iOS/Mac by ensuring visible NSIndexPaths are ordered consistently across section boundaries, and adds a HostApp repro page + Appium UI test for issue #17664.

Changes:

iOS (legacy Items/) and iOS/MacCatalyst (current Items2/) delegators now sort visible NSIndexPaths by Section then Row.
Added HostApp issue page (Issue17664) that displays the “last visible item” text while scrolling grouped content.
Added an Appium UI test (Issue17664) validating the label updates after a programmatic scroll.

PR: #34240 - [iOS & Mac] Fix for Incorrect ItemsViewScrolledEventArgs Values in CollectionView with Grouped Items
Platforms Affected: iOS, MacCatalyst (fix); Android fix is separate (PR #31437)
Files Changed: 2 implementation, 2 test

Key Findings

Root Cause: GetVisibleItemsIndexPath() called IndexPathsForVisibleItems.OrderBy(x => x.Row) — this sorted visible items by row index only. When a CollectionView is grouped (multiple sections), items from section 0 row 5 sorted before items from section 1 row 0, producing wrong First/Center/Last indices.
Fix: Sort by Section first, then Row: .OrderBy(x => x.Section).ThenBy(x => x.Row) — applied to both legacy Items/iOS/ItemsViewDelegator.cs and current Items2/iOS/ItemsViewDelegator2.cs.
Remaining concern (Copilot review): GetCenteredIndexPath still sorts only by .Row, so the null-fallback path (centerIndexPath ?? firstVisibleItemIndex) could return an incorrect index when the center point lands between cells and there are multiple sections. PR author dismissed this as "invalid."
Tests: UI test added (Issue17664.cs) — taps "Scroll to Category C, Item Update README.md #2" button, then waits for Issue17664DescriptionLabel to show "Category C item Update README.md #2". Test is wrapped with #if TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS, so it only runs on iOS/MacCatalyst.
Inline Copilot comment also noted PlatformAffected.iOS is missing macOS — PR author didn't update this.

❌ s/ai-reproduction-failed removed (was present from previous failed attempt due to build environment issue)

Build Environment Note

A pre-existing environment issue was encountered and resolved before verification:
The pre-built Microsoft.Maui.Controls.SourceGen.dll in artifacts referenced a BindingSourceGen.EnumIndex type (added in a later main commit, ad30170c), but the PR branch's BindingSourceGen source predates that commit and lacks EnumIndex. Rebuilding Controls.SourceGen from the PR branch's source resolved the MAUIG1001 build errors. This is a build environment version-skew issue unrelated to the PR itself.

Verdict

🟢 GATE: PASSED

Tests FAIL without the fix (bug is reproducible and caught by tests)
Tests PASS with the fix (fix correctly resolves the issue)
PR [iOS/Mac] CollectionView: Fix incorrect ItemsViewScrolledEventArgs indices with grouped items #34240 is validated: the fix for incorrect ItemsViewScrolledEventArgs indices in grouped CollectionView on iOS/MacCatalyst is correct and fully covered by the test.

Fix Summary

Root Cause: In GetVisibleItemsIndexPath(), IndexPathsForVisibleItems was sorted only by .Row. On grouped CollectionViews (multiple UICollectionView sections), items from section 0 row 5 sorted before items from section 1 row 0, producing wrong first/last visible item indices.

PR Fix: Changed sort from .OrderBy(x => x.Row) to .OrderBy(x => x.Section).ThenBy(x => x.Row) in GetVisibleItemsIndexPath(). Applied identically in both:

src/Controls/src/Core/Handlers/Items/iOS/ItemsViewDelegator.cs (legacy handler)
src/Controls/src/Core/Handlers/Items2/iOS/ItemsViewDelegator2.cs (current handler)

Result: Fix is correct, minimal, and directly addresses the root cause.

Code Quality Notes

✅ What the PR does well

Minimal change (1 meaningful line per file) that directly addresses the root cause
Applied consistently to both the legacy (Items/) and current (Items2/) handlers
Good comment added explaining the sort rationale
Test reproduces the bug accurately and verifies the fix
>= 0 guard added for LastVisibleItemIndex (addresses Copilot feedback)

⚠️ Minor Issues (non-blocking)

GetCenteredIndexPath() fallback still uses .OrderBy(x => x.Row) only:
Both files have a private GetCenteredIndexPath() method that also calls .OrderBy(x => x.Row) as a fallback when IndexPathForItemAtPoint returns null. The PR author dismissed the Copilot review comment as "invalid," but this is a real edge case: if the center point lands on a section header/footer (returning null), the fallback uses the wrong "first" index path from the incorrectly sorted list.

In practice this path is rarely hit (headers/footers are typically thin), and the existing test does not exercise it. This is a pre-existing pattern and not introduced by this PR, but it is a missed opportunity.
PlatformAffected.iOS should include macOS:
The [Issue] attribute on the HostApp page specifies PlatformAffected.iOS only, but the PR fixes both iOS and MacCatalyst handlers and the PR description validates on Mac. Non-blocking metadata issue.
#if TEST_FAILS_ON_ANDROID guard:
The test wraps with #if TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS, meaning it only runs on iOS/MacCatalyst. The Android fix (PR [Android] Fix for Incorrect ItemsViewScrolledEventArgs Values in CollectionView with Grouped Items #31437) has already landed. If Android's TEST_FAILS_ON_ANDROID constant has been removed in main, the guard could now be simplified. This is a minor cleanup item.

Recommendation

✅ APPROVE

The PR fix is correct, minimal, well-tested, and validated by both Gate and independent try-fix exploration. No alternative approach outperforms it on simplicity. The minor issues noted above (GetCenteredIndexPath fallback, PlatformAffected metadata) are non-blocking and can be addressed in a follow-up.

Suggested follow-up (optional): Apply the same Section/Row sort to the GetCenteredIndexPath() fallback path in both files for completeness, since it has the same root problem for edge cases involving null IndexPathForItemAtPoint results.

Result: ✅ APPROVED — PR Fix is Correct and Optimal

Phase 1: Title & Description

🟡 Title: Minor Improvement Suggested

Current: [iOS & Mac] Fix for Incorrect ItemsViewScrolledEventArgs Values in CollectionView with Grouped Items

Assessment:

The content is accurate and searchable ✅
& Mac is informal; MAUI convention uses MacCatalyst (or [iOS/Mac] slash form)
Fix for prefix is slightly verbose — omitting it is standard

Recommended:

[iOS/Mac] CollectionView: Fix incorrect ItemsViewScrolledEventArgs indices with grouped items

✅ Description: Good — Minor Cleanup Needed

Quality assessment:

Dimension	Rating	Notes
Structure	✅	Clear labeled sections
NOTE block	✅	Present at top
Root cause	✅	Clearly states sort-by-Row-only bug
Description of change	✅	File-by-file breakdown mentioning both Items/ and Items2/
Issues fixed	✅	`Fixes #17664` present
Platforms tested	✅	All four checked
Android cross-reference	✅	Links to PR #31437
Output/Before-After	❌	Table rows contain empty image markdown — no actual screenshots attached

Only change needed:

Remove the empty Before/After table or replace with actual screenshots / GIF. Currently the table cells are empty (| | |), which adds noise without value.

Recommended action: Delete or fill the Output section. Everything else is accurate and complete — do not rewrite the description.

Phase 2: Code Review

✅ Core Fix — `Items/iOS/ItemsViewDelegator.cs` & `Items2/iOS/ItemsViewDelegator2.cs`

The fix is minimal, correct, and well-explained.

// Before
var indexPathsForVisibleItems = collectionView.IndexPathsForVisibleItems.OrderBy(x => x.Row).ToList();

// After (both files)
// Sort visible item index paths by section and then by row for consistent order in both grouped and ungrouped sources
var indexPathsForVisibleItems = collectionView.IndexPathsForVisibleItems.OrderBy(x => x.Section).ThenBy(x => x.Row).ToList();

Analysis:

UICollectionView.IndexPathsForVisibleItems returns index paths in unspecified order. Sorting by Row alone produces wrong results when items from multiple sections are visible simultaneously because Row resets to 0 per section.
Adding .OrderBy(x => x.Section).ThenBy(x => x.Row) gives a globally consistent, ascending order across section boundaries — exactly what's needed for computing FirstVisibleItemIndex, CenterItemIndex, and LastVisibleItemIndex.
The comment added on each changed line explains the intent clearly ✅
The fix is applied to both the legacy handler (Items/) and the current handler (Items2/) — correct per the MAUI repo convention that Items/ serves Android/Windows/legacy-iOS and Items2/ serves current iOS/MacCatalyst ✅
No breaking change for ungrouped sources: single-section sources always have Section == 0, so the secondary ThenBy(Row) produces the same result as the old single-key sort ✅

🟡 Minor Issues

1. `PlatformAffected.iOS` does not include MacCatalyst

File: src/Controls/tests/TestCases.HostApp/Issues/Issue17664.cs, line 5

[Issue(IssueTracker.Github, 17664, "...", PlatformAffected.iOS)]

The fix in Items2/ applies to both iOS and MacCatalyst. The [Issue] attribute should reflect this:

[Issue(IssueTracker.Github, 17664, "...", PlatformAffected.iOS | PlatformAffected.MacCatalyst)]

This is a non-breaking annotation issue and does not affect test execution, but it does affect discoverability and accuracy.

2. Empty Before/After table in PR description

Location: PR description ### Output section

The Before/After table rows contain no content. This should either be populated with actual screenshots/recordings or removed to avoid confusing reviewers.

✅ Looks Good

src/Controls/tests/TestCases.HostApp/Issues/Issue17664.cs

Uses C# only (no XAML) — preferred pattern ✅
All interactive elements have AutomationId set ✅
Clear CollectionView with grouped ObservableCollection setup that directly reproduces the issue scenario ✅
Scrolled event handler safely guards the index: e.LastVisibleItemIndex >= 0 && < flatItems.Count ✅
No obsolete APIs used ✅

src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue17664.cs

#if TEST_FAILS_ON_ANDROID && TEST_FAILS_ON_WINDOWS correctly gates the test to run only on iOS and MacCatalyst ✅
Comment explains why Windows and Android are excluded, not just that they are ✅
Inherits from _IssuesUITest ✅
Single [Category(UITestCategories.CollectionView)] attribute ✅
No inline #if directives inside the test method body ✅
Test is simple and deterministic: scroll to known item → assert label text ✅

Summary

Area	Status	Action Required
Title	🟡 Minor	Optional: adopt `[iOS/Mac]` and drop `Fix for` prefix
NOTE block	✅ Good	None
Description accuracy	✅ Good	Remove empty Before/After table
Core fix (logic)	✅ Correct	None
Both handlers fixed	✅ Complete	None
HostApp test page	🟡 Minor	Change `PlatformAffected.iOS` → `PlatformAffected.iOS \| PlatformAffected.MacCatalyst`
UI test	✅ Good	None
Platform gating	✅ Correct	None

Overall verdict: The implementation is correct and the PR is in good shape. Two minor clean-ups recommended before merge:

Update PlatformAffected to include MacCatalyst.
Remove or populate the empty Before/After screenshot table from the description.
