DevExpress Universal 25.2は、アプリがユーザーの意図を解釈し、実行時にUIコンポーネントやロジックに変更を直接適用できる新しいAPIを追加

DevExpress Universal is a comprehensive suite of UI components and developer tools that supports the creation of feature-rich applications across web, desktop, and mobile platforms, including .NET, JavaScript, Blazor, ASP.NET, WinForms, WPF, and MAUI. It focuses on delivering consistent user interfaces, advanced data visualization, reporting, dashboards, and productivity features that help teams design, build, and maintain complex applications using a unified set of technologies and patterns.

DevExpress Universal v25.2 introduces AI Tool Calling (Natural Language Control for UI Components), a cross-platform feature that extends Microsoft.Extensions.AI tool-calling to enable natural-language interaction with application UI and logic. Developers can expose UI components, ViewModels, and business services as AI-invokable tools, grouped into dynamic toolsets that adapt to the application’s current context. When users interact through the DevExpress AI Chat Control, the language model interprets their request, selects the appropriate tool, resolves the target instance, and executes the action in real time, making applications easier to use while giving developers full control over what the AI can see and do.

DevExpress Universal is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. See our DevExpress Universal licensing page for full details.

ComponentOne Studio WinForms 2025 v2は、FlexPieを横に揃えたラベルで、よりきれいなビジュアルと読みやすさを向上

ComponentOne Studio WinForms by MESCIUS is a comprehensive toolkit offering over 120 advanced UI components to improve Windows Forms application development. It helps you to build visually appealing and feature-rich applications with functionalities like data visualization through charts and reports, intuitive data editing with performant grids, and modern UI elements including ribbons and docking for a user-friendly experience.

The ComponentOne Studio WinForms 2025 v2 update introduces a new data label placement option for FlexPie that aligns labels along the left and right sides of the chart to improve readability and visual structure. By moving labels out of the pie area, this option reduces overlap and congestion when working with datasets that contain many slices or small values, which are common challenges in pie chart rendering. The result is a more consistent and predictable layout that helps developers present data more clearly while maintaining a clean, modern appearance across different screen sizes and data scenarios.

To see a full list of what's new in 2025 v2, see our release notes.

ComponentOne Studio WinForms is licensed per developer on a perpetual basis and includes a 12 month subscription. Priority Support is also available. See our ComponentOne Studio WinForms licensing page for full details.
