[Windows, Android] ScrollView Content Not Removed When Set to Null #33067
Description
Description
When setting ScrollView.Content = null in .NET MAUI, the previous content is not removed on Android and Windows platforms. As a result, the old view remains in the UI.
Steps to Reproduce
public partial class MainPage : ContentPage { ScrollView _scrollView = null!; Label _originalContent = null!; Button _setNullButton = null!; public MainPage() { CreateUI(); } void CreateUI() { _originalContent = new Label { Text = "This is a sample label inside the ScrollView that can be set to null and added back.", Padding = new Thickness(20), AutomationId = "ContentLabel", FontSize = 16 }; _scrollView = new ScrollView { BackgroundColor = Colors.LightGray, HeightRequest = 300, Content = _originalContent }; _setNullButton = new Button { Text = "Set Content to Null", AutomationId = "SetNullButton" }; _setNullButton.Clicked += OnSetContentNullClicked; var layout = new VerticalStackLayout { Spacing = 20, Padding = new Thickness(30), Children = { _setNullButton, _scrollView } }; Content = layout; } void OnSetContentNullClicked(object? sender, EventArgs e) { _scrollView.Content = null; } void OnAddContentClicked(object sender, EventArgs e) { if (_originalContent != null) { _scrollView.Content = _originalContent; } } } 1.Paste the above code in MainPage.xaml.cs
2.Click the Set Content to Null button.
3. Observe the behavior in Windows and Android.
Expected Behavior
When ScrollView.Content is set to null, the ScrollView should remove the existing content and appear empty on all platforms.
Actual Behavior
The previous content is not removed. Old UI elements remain inside the ScrollView.
