[Android/iOS] Fix IsEnabled=False on CollectionView not working by devanathan-vaithiyanathan · Pull Request #27749 · dotnet/maui

devanathan-vaithiyanathan · 2025-02-12T15:05:54Z

Root Cause

When IsEnabled is set to false, CollectionView should not allow item selection. However, the IsEnabled state was not properly handled on both iOS and Android, allowing selection even when it was expected to be disabled.

Description of Change

iOS: Disabled UserInteractionEnabled based on the IsEnabled state to prevent any user interaction.
Android: Disabled PlatformView and restricted touch interactions by overriding OnTouchEvent in MauiRecyclerView

Issues Fixed

Fixes #27770

Tested the behavior in the following platforms.

Android
Windows
iOS
Mac

 			[Controls.ItemsView.IsVisibleProperty.PropertyName] = MapIsVisible,
-			[Controls.ItemsView.ItemsUpdatingScrollModeProperty.PropertyName] = MapItemsUpdatingScrollMode
+			[Controls.ItemsView.ItemsUpdatingScrollModeProperty.PropertyName] = MapItemsUpdatingScrollMode,
+			#if IOS || ANDROID


The behavior is the expected on Catalyst and Windows?

@jsuarezruiz ,
Yes, this behavior is expected on Windows. With the current iOS changes, it is now applicable to Mac as well

+		public override bool OnTouchEvent(MotionEvent e)
+		{
+			if (!Enabled)


I think at this point should also take into account the InputTransparent property.

@jsuarezruiz,
Without my changes, InputTransparent is already working fine for CollectionView. Let me know if any additional modifications are needed.

Pull request overview

This PR fixes a bug where CollectionView items could be selected even when IsEnabled was set to false. The fix implements proper enabled state handling on both iOS and Android platforms by disabling user interaction at the platform control level and adding checks in selection logic.

Key Changes

iOS: Disables UserInteractionEnabled on the UICollectionView when IsEnabled is false
Android: Overrides OnTouchEvent in MauiRecyclerView to block touch events and adds a check in SelectableItemsViewAdapter to prevent selection when disabled
Adds UI test to verify the disabled state prevents selection and enabled state allows selection

The test files are using issue number 20274 in both the file names and code, but the PR description indicates this PR fixes issue #27770. The issue numbers should match. Consider renaming the test files to Issue27770.cs, Issue27770.xaml, and Issue27770.xaml.cs, and updating the [Issue] attribute to reference the correct issue number 27770.

+				selectedItem.Name = $"{selectedItem.Name} - Selected";
+				this.label.Text = selectedItem.Name;


The test logic appears to be incorrect. The test starts with the CollectionView disabled (IsEnabled="False"), taps an item (which should be ignored), then verifies the label shows "Item 1" (the initial state). Then it enables the CollectionView by clicking the button, taps the item again, and expects "Item 1 - Selected". However, there's a bug: on line 28 of the code-behind, when an item is selected, the item's name is mutated to append " - Selected", which means on subsequent selections, it would become "Item 1 - Selected - Selected" and so on. This test only works once. Consider resetting the item name when the CollectionView is re-enabled or using a different mechanism to track selection state.

Suggested change

selectedItem.Name = $"{selectedItem.Name} - Selected";

this.label.Text = selectedItem.Name;

this.label.Text = $"{selectedItem.Name} - Selected";

+            return base.OnTouchEvent(e);


The indentation is inconsistent. Line 544 uses spaces while line 545 uses tabs (or different spacing). The codebase should maintain consistent indentation. Based on the surrounding code context, use tabs for indentation to match the rest of the file.

Suggested change

return false;

return base.OnTouchEvent(e);

return false;

return base.OnTouchEvent(e);

🤖 Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against #2 automatically generated candidates and selected try-fix-2 as the strongest fix.

Why: try-fix-2 passed the iOS regression test and fixes disabled CollectionView selection through native selection capability instead of UserInteractionEnabled, avoiding the PR fix's InputTransparent clobbering risk. try-fix-1 failed validation, and pr/pr-plus-reviewer are ranked lower because they rely on broader UIKit interaction state.

Please consider applying the candidate diff below (or use it as guidance). Once you push an update, this workflow will re-trigger and re-evaluate.

🤖 Automated review — alternative fix proposed

The expert-reviewer evaluation compared the PR fix against #1 automatically generated candidates and selected try-fix-1 as the strongest fix.

Why: try-fix-1 passed the requested iOS regression test and fixes the root native disabled-state behavior by propagating IsEnabled to UICollectionView.UserInteractionEnabled. It is simpler and safer than the raw PR and pr-plus-reviewer because it avoids unnecessary selection-controller changes while covering MacCatalyst mapper registration.

Please consider applying the candidate diff below (or use it as guidance). Once you push an update, this workflow will re-trigger and re-evaluate.

Issue: #27770 - [iOS/Android] CollectionView IsEnabled Not Working
PR: #27749 - [Android/iOS] Fix IsEnabled=False on CollectionView not working
Platforms Affected: iOS, Android (testing platform requested: ios)
Files Changed: 5 implementation, 3 test

Key Findings

The issue reports that CollectionView.IsEnabled=false still permits user interaction/selection on iOS and Android.
The current PR diff in the review branch changes iOS legacy Items/ and current Items2/ handlers plus an Appium UI regression test; the PR narrative still mentions Android changes, but the available diff is Apple handler/test focused.
Gate was already completed externally: tests fail without the fix and pass with the PR fix. This phase did not re-run gate verification and did not create or overwrite gate/content.md.
Review comments raised cross-platform behavior and InputTransparent considerations; current active platform for this run is iOS.
The new UI test is a CollectionView Appium test named Issue20274 despite the linked issue being [iOS/Android] CollectionView IsEnabled Not Working #27770.

Code Review Summary

Verdict: NEEDS_CHANGES
Confidence: high
Errors: 3 | Warnings: 0 | Suggestions: 0

Key code review findings:

❌ src/Controls/src/Core/Handlers/Items/ItemsViewHandler.iOS.cs:102 - the new IsEnabled mapper replaces inherited native enabled-state mapping but only updates selection mode.
❌ src/Controls/src/Core/Handlers/Items2/ItemsViewHandler2.iOS.cs:127 - same CV2 issue: runtime IsEnabled changes do not preserve native UICollectionView.UserInteractionEnabled updates.
❌ src/Controls/src/Core/Handlers/Items/ItemsViewHandler.cs:32 - legacy mapper entry is behind #if IOS; if legacy Apple behavior is intended for MacCatalyst too, it should include MACCATALYST.

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
PR	PR #27749	Add iOS mapper entries, block selection callbacks when `!IsExplicitlyEnabled`, and gate `AllowsSelection` / `AllowsMultipleSelection` by enabled state.	✅ PASSED (Gate)	5 implementation, 3 test	Original PR; gate result supplied by caller.

🔬 Code Review — Deep Analysis

Code Review — PR #27749

Independent Assessment

What this changes: Adds iOS/CV2 CollectionView IsEnabled mapping so selection callbacks and AllowsSelection/AllowsMultipleSelection respect IsExplicitlyEnabled; adds an Appium UI test page for disabled CollectionView selection.
Inferred motivation: Prevent user item selection when CollectionView.IsEnabled=false.

Reconciliation with PR Narrative

Author claims: Fixes CollectionView IsEnabled=false for Android/iOS, disables native interaction, tested Android/Windows/iOS/Mac.
Agreement/disagreement: Current diff is Apple handler/test-only. More importantly, the new mapper blocks selection but does not preserve native UserInteractionEnabled updates.

Findings

❌ Error — Native enabled state no longer updates in legacy iOS handler

src/Controls/src/Core/Handlers/Items/ItemsViewHandler.iOS.cs:102

The new IsEnabled mapper replaces inherited ViewHandler.MapIsEnabled, but only calls UpdateSelectionMode(). Base behavior calls UIView.UpdateIsEnabled, which sets UserInteractionEnabled. Disabled CollectionViews can still scroll/receive non-selection gestures. Preserve native enabled mapping before updating selection mode.

❌ Error — Native enabled state no longer updates in CV2 handler

src/Controls/src/Core/Handlers/Items2/ItemsViewHandler2.iOS.cs:127

Same issue for CV2: the override replaces base mapping and only toggles selection. UICollectionView.UserInteractionEnabled is not kept in sync for runtime IsEnabled changes.

❌ Error — MacCatalyst missing legacy mapper entry

src/Controls/src/Core/Handlers/Items/ItemsViewHandler.cs:32

The mapper entry is behind #if IOS, but the paired .iOS.cs implementation also compiles for MacCatalyst. Use #if IOS || MACCATALYST if this behavior is intended for both Apple platforms.

Devil's Advocate

The selection guards do address the specific tap-selection path, but the PR narrative claims native interaction is disabled; replacing the base mapper proves that is not true for other interactions. The MacCatalyst concern follows existing repo patterns (IOS || MACCATALYST) and platform-file rules.

Verdict: NEEDS_CHANGES

Confidence: high
Summary: The core fix is incomplete because it regresses native IsEnabled handling while adding selection-only behavior. CI is also currently failing (maui-pr/Build Analysis), so this is not ready to merge. Inline findings were written to CustomAgentLogsTmp/PRState/27749/PRAgent/inline-findings.json.

🔧 Fix — Analysis & Comparison

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix-1	Native iOS interaction gating via `ViewHandler.MapIsEnabled` + `UICollectionView.UpdateIsEnabled`; leaves selection callbacks/mode unchanged.	✅ PASS	3 files	Better than PR fix: preserves native enabled behavior, handles scrolling/non-selection gestures, includes MacCatalyst mapper guard, and avoids controller selection logic changes.
PR	PR #27749	Selection-callback guards plus enabled-state gating of `AllowsSelection` / `AllowsMultipleSelection`.	✅ PASSED (Gate)	5 implementation, 3 test	Original PR; gate result supplied by caller. Code review found native enabled-state preservation concerns.

Cross-Pollination

Model	Round	New Ideas?	Details
maui-expert-reviewer	1	Yes	Proposed native interaction gating with `ViewHandler.MapIsEnabled` and `UICollectionView.UpdateIsEnabled`, not selection delegate guards.

Exhausted: No — stopped because candidate #1 passed all requested iOS regression testing and is demonstrably better than the PR fix.
Selected Fix: Candidate #1 — It passes the iOS UI regression test while preserving native IsEnabled semantics and reducing the implementation surface from selection controller logic to handler-level native enabled-state propagation.

try-fix-1 — Native Interaction Gating

Approach Description

Use native iOS interaction disabling instead of selection-callback guards. The candidate adds IsEnabled mapper entries for Apple CollectionView handlers, calls ViewHandler.MapIsEnabled, and explicitly applies UpdateIsEnabled to the underlying UICollectionView.

📋 Report — Final Recommendation

Comparative Report — PR #27749

Candidates compared

Rank	Candidate	Regression result	Assessment
1	`try-fix-1`	✅ PASS	Best candidate. It fixes the root iOS behavior by propagating `IsEnabled` to the native `UICollectionView.UserInteractionEnabled` state, includes the MacCatalyst mapper guard, and leaves selection callbacks/mode semantics unchanged.
2	`pr-plus-reviewer`	Not re-run in this phase	Addresses the expert review findings by adding native enabled-state propagation and MacCatalyst coverage to the PR fix. It should resolve the raw PR's correctness issues, but it retains extra selection-controller changes that are unnecessary once native interaction is disabled.
3	`pr`	✅ PASS (supplied gate)	Passes the targeted selection regression, but expert review found major correctness issues: the custom `IsEnabled` mapper replaces inherited native enabled-state mapping, so disabled CollectionViews can still scroll/receive non-selection native interaction; legacy MacCatalyst coverage is also missing.

Analysis

The raw PR fix is correctly aimed at preventing disabled CollectionViews from changing selection, and the supplied gate confirms the new iOS regression test fails without the fix and passes with the PR. However, the implementation fixes the symptom at the selection delegate/selection-mode layer rather than the native enabled-state layer. Because UICollectionView is not a UIControl, correct disabled behavior requires updating UserInteractionEnabled; replacing the inherited IView.IsEnabled mapper without preserving that behavior leaves non-selection interaction enabled.

pr-plus-reviewer is a viable PR-derived candidate because it incorporates the expert feedback: it restores native enabled-state propagation and includes MacCatalyst in the legacy handler mapper guard. That removes the major review findings while keeping the PR's tests. Its downside is unnecessary complexity: the additional ItemSelected / ItemDeselected guards and AllowsSelection gating duplicate behavior that native interaction disabling already provides.

try-fix-1 is the cleanest and most robust solution. It directly updates the native interaction surface through the handler mapper, uses the existing UICollectionView.UpdateIsEnabled path, covers both iOS and MacCatalyst mapper registration where applicable, and avoids touching selection controller logic. It also passed the requested iOS regression command in STEP 6a.

Winner

try-fix-1 wins. It passed regression testing and fixes the broader disabled interaction behavior with a smaller, more idiomatic MAUI handler change than either the raw PR or the PR-plus-reviewer candidate.

Issue: #27770 — [iOS/Android] CollectionView IsEnabled Not Working (closely related to #20274, which is the issue number used in the test files)
PR: #27749 — [Android/iOS] Fix IsEnabled=False on CollectionView not working
Platforms Affected: iOS (and MacCatalyst — but not handled by this PR). PR title and description also claim Android, but no Android code is in the diff.
Files Changed: 3 implementation (all iOS CollectionView handlers), 3 test (one UITest + xaml + xaml.cs HostApp page).

Key Findings

The PR registers a new IsEnabled mapper on ItemsViewHandler (legacy CV) and ItemsViewHandler2 (CV2) that sets Controller.CollectionView.UserInteractionEnabled = itemsView.IsEnabled. This works because the legacy handler's PlatformView is Controller.View (an outer wrapper), so the base ViewHandler.MapIsEnabled only disables the wrapper — touches still reach the inner UICollectionView.
The legacy mapper registration is gated by #if IOS, which excludes MacCatalyst (the IOS symbol is iOS-only; MacCatalyst uses MACCATALYST). This contradicts the PR description, which claims Mac was tested.
The ItemsViewHandler2 registration lives in ItemsViewHandler2.iOS.cs and is not guarded — so CV2 picks up the fix on both iOS and MacCatalyst, but legacy CV does not. Inconsistent platform coverage between the two handlers.
PR description claims "Android: Disabled PlatformView and restricted touch interactions by overriding OnTouchEvent in MauiRecyclerView," but the actual diff contains zero Android changes (the prior MauiRecyclerView.cs edit visible in old inline comments was removed during rebase).
Both new mappers fully shadow the base ViewHandler.MapIsEnabled (same key nameof(IView.IsEnabled)). The base's UpdateIsEnabled no longer runs for these handlers; this happens to be benign on iOS but is a maintainability concern.
Test/HostApp uses issue number 20274 in file names while the PR Fixes #27770. Copilot already flagged this and a mutable model state issue (selection appends " - Selected" to bound Name, breaking the test on re-runs).

Code Review Summary

Verdict: NEEDS_CHANGES
Confidence: high
Errors: 1 | Warnings: 4 | Suggestions: 4

Key code review findings:

❌ src/Controls/src/Core/Handlers/Items/ItemsViewHandler.cs:32 — #if IOS excludes MacCatalyst; legacy CV never gets the fix on Mac. Should be #if IOS || MACCATALYST, or better, move the mapper entry into ItemsViewHandler.iOS.cs (the pattern Items2 already uses).
⚠️ src/Controls/src/Core/Handlers/Items/ItemsViewHandler.iOS.cs:100 — Base ViewHandler.MapIsEnabled is shadowed; consider AppendToMapping or call base first.
⚠️ src/Controls/src/Core/Handlers/Items2/ItemsViewHandler2.iOS.cs:36 — Same base-mapper shadowing.
⚠️ PR description claims Android changes, but the diff has none — title and description are misleading.
⚠️ src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue20274.cs:23 — Test will likely fail on MacCatalyst (legacy CV mapper not registered there) and is brittle because selectedItem.Name is mutated on every selection.
💡 Architectural inconsistency between Items legacy (#if-guarded in shared file) and Items2 (in .iOS.cs partial).
💡 Test coverage gap: doesn't verify toggling IsEnabled back to false.
💡 Minor indentation: #if/#endif indented with tabs; house style is column 0.
💡 HostApp page mutates bound Name (appends " - Selected") — fragile on repeated taps.

🔬 Code Review — Deep Analysis

Code Review — PR #27749

Independent Assessment

What this changes: Adds an IsEnabled mapper to both ItemsViewHandler<TItemsView> (legacy CV) and ItemsViewHandler2<TItemsView> (CV2) that, on iOS, sets Controller.CollectionView.UserInteractionEnabled to match ItemsView.IsEnabled. Also adds a UI test (Issue20274) and HostApp page (xaml + code-behind) that toggle IsEnabled and verify selection is blocked/allowed accordingly.

Inferred motivation: The PlatformView returned by ItemsViewHandler.CreatePlatformView() is Controller.View — the outer UICollectionViewController.View wrapper — not the inner UICollectionView. The base ViewHandler.MapIsEnabled calls platformView.UpdateIsEnabled(view) on that outer wrapper, which (apparently) doesn't propagate to block selection on the inner UICollectionView reliably. So the fix explicitly disables interaction on the inner UICollectionView.

Reconciliation with PR Narrative

Author claims:

"iOS: Disabled UserInteractionEnabled based on the IsEnabled state to prevent any user interaction." ✅ matches code.
"Android: Disabled PlatformView and restricted touch interactions by overriding OnTouchEvent in MauiRecyclerView." ❌ no Android code in the actual diff (gh pr view 27749 --json files returns 6 files, all iOS/test). Inline comment history shows there was once an Android edit at MauiRecyclerView.cs:545, but it's been removed.
"Tested on Android, Windows, iOS, Mac." ⚠️ The legacy ItemsViewHandler mapper is gated by #if IOS, so MacCatalyst doesn't get the fix for the legacy CV path. CV2 is unguarded (lives in .iOS.cs partial) and does work on Mac, but legacy CV does not.

Agreement/disagreement: Agree the iOS fix is the right shape. Disagree that Mac is covered — there's an inconsistency between legacy CV (iOS only) and CV2 (iOS + Mac). Disagree that Android is fixed — no Android code is present.

Findings

❌ Error — MacCatalyst is excluded for legacy CV

src/Controls/src/Core/Handlers/Items/ItemsViewHandler.cs:32

#if IOS
[nameof(IView.IsEnabled)] = MapIsEnabled,
#endif

The IOS compilation symbol is defined only for net*-ios. MacCatalyst uses the MACCATALYST symbol. The reference platform code itself uses #if IOS || MACCATALYST for this kind of case (e.g., src/Core/src/Handlers/View/ViewHandler.cs:611). As written, the legacy ItemsViewHandler never registers the IsEnabled mapper on MacCatalyst, so the bug persists there.

Suggested fix: Either change to #if IOS || MACCATALYST, or move the entry into ItemsViewHandler.iOS.cs (the Items2 pattern already does this and works for both TFMs).

⚠️ Warning — Base ViewHandler mapper is shadowed (legacy)

src/Controls/src/Core/Handlers/Items/ItemsViewHandler.iOS.cs:100

The new mapper uses the same key (nameof(IView.IsEnabled)) as ViewHandler's base mapper, fully replacing it. The base mapper calls platformView.UpdateIsEnabled(view) on Controller.View — that's now skipped. On iOS this is currently benign because UpdateIsEnabled on the outer wrapper had no useful effect anyway, but future contributors who modify the base mapper (e.g., to add accessibility hooks) will silently miss CollectionView.

Suggested fix: Either invoke ViewHandler.MapIsEnabled(handler, itemsView) first, then set CollectionView.UserInteractionEnabled; or use Mapper.AppendToMapping(...) instead of overriding the dictionary slot.

⚠️ Warning — Base ViewHandler mapper is shadowed (Items2)

src/Controls/src/Core/Handlers/Items2/ItemsViewHandler2.iOS.cs:36

Same shadowing as above for CV2. Same suggested fix.

⚠️ Warning — PR description does not match the diff (Android missing)

The PR title says [Android/iOS] and the description includes an entire Android change paragraph and a "Tested on Android" checkbox, but the diff has no Android files. Either re-add the Android fix or update the title/description/before-after media to reflect iOS-only. The linked issue (#27770) is marked Android, iOS as affected platforms.

⚠️ Warning — Test brittleness and platform coverage

src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue20274.cs:23

The HostApp code (Issue20274.xaml.cs:29) mutates the bound model's Name on every selection by appending " - Selected". The test re-taps the same item after re-enabling — that works once, but if the test or any re-run order changes, the second tap would yield "Item 1 - Selected - Selected". Also, the test has [Category(UITestCategories.CollectionView)] with no platform exclusion, so on MacCatalyst (where legacy CV is not patched) the first assertion Is.EqualTo("Item 1") would fail.

Suggested fix: Set label.Text directly to $"{selectedItem.Name} - Selected" without mutating selectedItem.Name. Optionally add a [Platform] filter or wait until the MacCatalyst gap is closed.

💡 Suggestion — Architectural inconsistency between Items and Items2 registration sites

ItemsViewHandler.cs puts the entry in the shared file behind #if IOS; ItemsViewHandler2.iOS.cs puts it in the iOS partial. Pick one pattern. Putting both in the .iOS.cs partial is cleaner (no preprocessor in shared file) and naturally covers MacCatalyst since .iOS.cs compiles for both TFMs.

💡 Suggestion — Add re-toggle coverage

The test toggles IsEnabled once (false → true). Consider asserting that toggling back to false again re-blocks selection.

💡 Suggestion — Style: preprocessor indentation

#if IOS / #endif should be at column 0 per repo style.

💡 Suggestion — Don't mutate bound model state

Move the " - Selected" suffix into the Label.Text assignment rather than the model property — keeps the items source clean across re-runs.

Devil's Advocate

Maybe #if IOS was deliberate to scope to iOS only. The PR explicitly claims Mac was tested, and Items2 (no guard) does cover Mac — so the asymmetry between Items and Items2 is unintentional inconsistency, not deliberate scoping.
Maybe UICollectionViewController.View.UserInteractionEnabled = false would already work. UIView's userInteractionEnabled = false does propagate to subviews — but the base mapper here doesn't actually set that on the outer wrapper in a way that survives Controller setup (the outer view's interaction was already left enabled by the controller infra). The bug existing in the wild confirms the base path doesn't work; setting it on the inner CV is the safest reliable fix.
Is the mapper shadowing actually a problem? Today, no. Tomorrow, when somebody adds a side effect to the base MapIsEnabled, yes. Worth AppendToMapping or explicit base call.

Verdict: NEEDS_CHANGES

Confidence: high
Summary: The iOS fix shape is right and the gate confirms it works on iOS, but the legacy ItemsViewHandler change is silently MacCatalyst-blind due to #if IOS, while ItemsViewHandler2 covers Mac — that asymmetry plus the missing Android changes claimed in the PR description need to be resolved before merge. Switching the legacy registration to #if IOS || MACCATALYST (or moving it into ItemsViewHandler.iOS.cs) is a one-line fix that closes the platform gap and aligns the two handler variants.

### Root Cause When IsEnabled is set to false, CollectionView should not allow item selection. However, the IsEnabled state was not properly handled on both iOS and Android, allowing selection even when it was expected to be disabled. ### Description of Change * iOS: Disabled UserInteractionEnabled based on the IsEnabled state to prevent any user interaction. * Android: Disabled PlatformView and restricted touch interactions by overriding OnTouchEvent in MauiRecyclerView ### Issues Fixed  Fixes #27770 **Tested the behavior in the following platforms.** - [x] Android - [x] Windows - [x] iOS - [x] Mac ### Output Screenshot | Before | After | |---------|--------| | **Android**<br> <video src="https://github.com/user-attachments/assets/e43ed3e8-5970-446a-a8bc-eb0de4e312d4" width="260" height="500"> |**Android**<br> <video src="https://github.com/user-attachments/assets/f8d1beef-445d-4c72-bc2c-2495f42ddfbd" width="260" height="500"> | | **iOS**<br> <video src="https://github.com/user-attachments/assets/659a7a38-72ae-4c93-8b3d-fed9137f0a50" width="300" height="600"> | **iOS**<br> <video src="https://github.com/user-attachments/assets/bb6fc013-bb5a-4d0e-85e7-2c0459aeea3b" width="300" height="600"> |
