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!

Root Cause:

ComboBox MinWidth wasn’t reset when the dropdown closed, which prevented it from resizing correctly.

Description of Change

Updated OnMauiComboBoxDropDownClosed in PickerHandler.Windows.cs to reset the ComboBox.MinWidth to 0 when the dropdown closes, allowing the picker to resize with its parent.

Already, ComboBox.MinWidth is set in two other places:

• When opening the ComboBox, where ComboBox.ActualWidth is assigned to ComboBox.MinWidth. So, the ComboBox.MinWidth will always be set every time the ComboBox is opened.
• After selecting an item, where 0 is already assigned to ComboBox.MinWidth, similar to our fix, and this also triggers the ComboBox’s closed event.

Issues Fixed

Fixes #32984

Tested the behavior in the following platforms

• Windows
• Android
• iOS
• Mac

Pull request overview

This PR fixes a Windows-specific Picker resize issue where the Picker control failed to shrink back after its parent container was resized. The root cause was that ComboBox.MinWidth was set when the dropdown opened but never reset when it closed, preventing the control from resizing smaller.

Key Changes:

• Adds logic to reset ComboBox.MinWidth to 0 when the dropdown closes on Windows
• Includes comprehensive UI test coverage with test page and automated test

Issue: #32984 - Picker items width won't resize back when its container window gets resized down.
PR: #33042 - [Windows] Fixed Picker items width wont resize back
Platforms Affected: Windows (primary), test runs on all platforms
Files Changed: 1 implementation, 2 test files + 4 platform snapshot PNGs

Key Findings

• Root cause: When the ComboBox dropdown opens, MinWidth is set to comboBox.ActualWidth (prevents shrinkage during open animation). When dropdown closes without item selection, MinWidth is never reset — so the ComboBox retains the previous large width, preventing resize-down.
• PR fix: In OnMauiComboBoxDropDownClosed, adds comboBox.MinWidth = 0 guarded by comboBox.MinWidth > 0. The guard avoids redundancy since OnControlSelectionChanged already sets MinWidth = 0 before DropDownClosed fires on item selection.
• Existing behavior: OnControlSelectionChanged at line 125 already does PlatformView.MinWidth = 0 — so the bug only manifests when dropdown is closed without selecting an item.
• Copilot inline review flagged: (1) the > 0 guard is unnecessary (both threads resolved), (2) platform-specific #if directives in test body should use extension methods (resolved). PR author defended the > 0 guard citing no redundant work on selection path.
• Test uses inline #if directives in the test method body (#if ANDROID, #if IOS || MACCATALYST, #if WINDOWS) — guideline says to prefer extension methods, but this is a resolved inline review comment.
• Trailing whitespace on line 15 of Issue32984.cs (HostApp): AutomationId = "issue32984Picker",\t
• Missing newline at end of both Issue32984.cs files (HostApp and Shared.Tests).
• BOM characters at start of test files (UTF-8 BOM ).

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix (claude-opus-4.6)	Save/Restore Original MinWidth — capture MinWidth before open, restore on close	✅ Pass	PickerHandler.Windows.cs	More robust: preserves intentionally-set MinWidth

Cross-Pollination

Model	Round	New Ideas?	Details
claude-opus-4.6	2	No	Space exhausted; recommended Attempt 2 (remove MinWidth entirely)
claude-sonnet-4.6	2	Yes	ClearValue(MinWidthProperty) instead of MinWidth=0 — semantically restores style defaults; functionally equivalent in practice
gpt-5.3-codex	2	Yes	IsDropDownOpen property-changed handler + SizeChanged self-heal — significantly more complex, no clear benefit

Exhausted: Yes (additional ideas are minor variations; ClearValue = functional equivalent of MinWidth=0 for ComboBox; IsDropDownOpen approach is over-engineered)

Selected Fix: PR's fix — the > 0 guarded reset in OnMauiComboBoxDropDownClosed is correct and conservative. Attempt 3 (unconditional reset, no guard) is a marginally cleaner variant of the same approach. The PR fix is acceptable as-is; the > 0 guard is an intentional author choice to skip a redundant assignment on the selection path.

Summary

PR #33042 fixes a Windows-only bug where the Picker (backed by WinUI ComboBox) fails to resize back when its parent container is resized smaller. The fix is a single targeted addition to PickerHandler.Windows.cs. All 4 independent try-fix attempts confirmed that the core approach (resetting MinWidth to 0 when the dropdown closes) is correct. The PR includes a well-scoped UI test that covers all platforms.

Root Cause

When the ComboBox dropdown opens, OnMauiComboBoxDropDownOpened sets comboBox.MinWidth = comboBox.ActualWidth to prevent the control from visually shrinking during the open animation. This MinWidth is reset to 0 in OnControlSelectionChanged (item selected path) but was never reset when the dropdown closed without selecting an item. This caused the ComboBox to retain the large MinWidth from the previous open, blocking any subsequent downward resize of the parent container.

Fix Quality

The PR's fix is correct, minimal, and well-placed:

if (sender is ComboBox comboBox && comboBox.MinWidth > 0)
{
    comboBox.MinWidth = 0;
}

Minor code quality notes (non-blocking):

1. comboBox.MinWidth > 0 guard is unnecessary. The Copilot inline reviewer flagged this; try-fix Attempt 3 confirmed an unconditional reset passes all tests identically. Setting MinWidth = 0 when it's already 0 is a no-op in WinUI — the guard adds complexity without measurable benefit. The author defended the guard as avoiding a redundant write, which is a reasonable position, but the code is slightly cleaner without it.

2. Inline #if directives in test body. Issue32984.cs (SharedTests) uses #if ANDROID / #elif IOS || MACCATALYST / #elif WINDOWS directly in the test method. Per MAUI UI testing guidelines, platform-specific logic should live in extension methods. This is a style violation that all inline reviewer threads marked resolved.

3. Trailing whitespace on line 15 of TestCases.HostApp/Issues/Issue32984.cs: AutomationId = "issue32984Picker",\t (tab at end of line).

4. Missing newline at end of file in both Issue32984.cs files (HostApp and SharedTests).

None of these block the fix from being correct and functional. The core implementation change is sound.

Selected Fix: PR's fix — conservative, minimal, and directly corrects the missed reset on the non-selection close path.
