[Testing] Feature matrix UITest Cases for Horizontal and Vertical Stack Layout by HarishKumarSF4517 · Pull Request #31393 · dotnet/maui

HarishKumarSF4517 · 2025-08-29T09:43:13Z

This pull request adds a new interactive feature matrix for StackLayout, including both horizontal and vertical layouts, to the test application. The addition includes new pages for demonstrating and configuring StackLayout behaviors, as well as a view model to support dynamic UI updates. This enables easier testing and exploration of layout options and properties.

New StackLayout Feature Matrix:

Added a new entry for "StackLayout Feature Matrix" to the list of gallery pages in CorePageView, making the new feature matrix accessible from the main test app navigation.
Introduced StackLayoutControlPage and StackLayoutControlMainPage (with XAML and code-behind) to showcase interactive examples of both HorizontalStackLayout and VerticalStackLayout, including nesting, spacing, alignment, and color demonstration. [1] [2]
Added StackLayoutOptionsPage (XAML and code-behind) to allow users to adjust layout orientation, visibility, flow direction (RTL/LTR), spacing, and rectangle dimensions through a toolbar-accessible options menu. [1] [2]
Implemented StackLayoutViewModel to support two-way data binding for layout properties, including orientation, visibility, flow direction, spacing, and rectangle size, with property change notifications for dynamic UI updates.

The Title attribute has a typo. It should be 'StackLayoutOptionsPage' instead of 'tackLayoutOptionsPage'.

Suggested change

Title="tackLayoutOptionsPage">

Creating a new StackLayoutViewModel instance discards any changes made in the current view model. This should retain the existing _viewModel state instead of creating a new instance.

Suggested change

BindingContext = _viewModel = new StackLayoutViewModel();

BindingContext = _viewModel;
