PROFILE
Joris Voermans
Joris contributed to the MaterialDesignInXamlToolkit repository, focusing on UI stability, maintainability, and developer experience over seven months. He delivered targeted bug fixes and feature enhancements in C# and XAML, such as refactoring converter logic for resource efficiency, stabilizing control templates, and improving binding reliability. Joris addressed layout regressions in components like SplitButton and Chip, restored dark mode functionality, and modernized XAML practices by balancing x:Reference and ElementName usage. His work emphasized robust MVVM patterns, resource management, and UI/UX consistency, resulting in reduced runtime errors, improved theming, and lower maintenance overhead for complex WPF applications in production environments.

Aug 1, 2025August 2025 monthly summary for MaterialDesignInXamlToolkit focused on stabilizing UI template bindings in core controls. Reverted a prior change that used x:Reference in Button and ProgressBar templates, replacing it with ElementName bindings to improve element resolution, consistency, and stability across themes and configurations. The change was implemented via a targeted revert in the toolkit (commit 471110fab1a55f631e2214030d943c43219e0032).

Jun 1, 2025June 2025: Stabilized UI bindings and improved visual rendering for MaterialDesignInXamlToolkit. Delivered robust binding fallbacks (RelativeSource FindAncestor), default CenterVertical alignment in PopupBox, and safe UI updates for TextBoxLineCountBehavior in virtualized DataGrid. Enhanced visuals with icon-less chip padding, centralized EllipseClipConverter for ToggleButton clipping, and modernization of XAML element referencing by using x:Reference in templates. Commits contributing include: 7ddc81f, f0f5fdc, 66b836b, 182b60a7, 556b412c, 442f311a.

May 1, 2025May 2025 monthly summary for MaterialDesignInXamlToolkit: UI refinements including restoration of dark mode functionality and a new Chip component padding customization. Restored dark mode by removing a conflicting theme configuration, ensuring consistent dark UI across environments. Implemented Chip padding customization by binding the TextBlock's Margin to the Chip.Padding (TemplateBinding), improving spacing and visual adaptability across chip instances. These changes enhance theming reliability, UI consistency, and developer flexibility, with low surface area for regressions and faster iteration cycles.

Apr 1, 2025April 2025 monthly summary for MaterialDesignInXamlToolkit. Focused on stabilizing SplitButton UI to ensure consistent margins and predictable layout across themes. Key change addressed a margin regression by removing the outer grid margin and explicitly setting zero margins on the internal SplitButton elements (button and popup), preventing visual layout problems and improving UI consistency.

Feb 1, 2025February 2025 monthly performance summary for MaterialDesignInXamlToolkit focused on stability and bug resolution in layout logic. Delivered a critical fix to the Badged control ArrangeOverride that previously could enter an infinite loop, by removing the premature reset of the badge container margin during recalculation. This change ensures correct badge positioning and prevents UI freezes during layout passes. No new user-facing features released this month; primary business value comes from improved reliability, reduced risk of layout glitches, and lower support burden. Demonstrated strong debugging, code quality, and maintainability in a complex WPF/XAML component.

Jan 1, 2025January 2025 monthly summary for MaterialDesignInXamlToolkit: Delivered targeted stability and API surface improvements that reduce runtime crashes and simplify developer usage. Two key changes contributed to product reliability and UI consistency across the toolkit. Key features delivered and major fixes: - Bug fix: TextBoxLineCountBehavior now guards UpdateAttachedProperties to avoid NullReferenceException when the AssociatedObject is null during detachment, improving runtime stability for TextBox-related behaviors. - Feature/UX improvement: Converter utilities for MaterialDesignThemes.Wpf were exposed and reorganized. Converter classes were made public, reorganized under an Internal namespace, and two obsolete converters were removed, improving developer experience and UI consistency. Overall impact and accomplishments: - Reduced crash potential in common TextBox usage scenarios, leading to more stable applications using the toolkit. - Cleaner API surface and streamlined conversions, easing adoption and reducing maintenance burden. Technologies/skills demonstrated: - C#, WPF behaviors, and MVVM patterns; API design and public surface changes; code refactoring and cleanup; attention to backward-compatibility and developer ergonomics.
