AIプロンプトでアプリの挙動を制御

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.

ビューアを通じてPDFコンテンツをキャプチャ

アプリがPDF文書からユーザーが選択したテキストや範囲を直接抽出できるようにし、取得したデータを画面上の可視的な操作と一致

Extracting content using a PDF Viewer refers to enabling end users or applications to select and retrieve content directly through the viewer’s user interface, based on interactive actions such as text selection, area selection, or page-level capture. For software developers, this means the viewer acts not only as a rendering surface but also as a controlled extraction layer that exposes selected text, images, or regions. This approach is valuable in review, approval, and data capture scenarios because it reflects explicit user intent, aligns extracted data with what is visibly selected on screen, and avoids reliance on background parsing alone, resulting in more predictable and user-driven content retrieval within applications.

Several WinForms PDF Viewer components allow content extraction, including:

  • DevExpress WinForms PDF Viewer (part of DevExpress WinForms) allows you to extract user-selected text and visual regions directly through the PDF viewer.
  • Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) allows you to capture visually selected PDF content in the viewer, returning text aligned with user interactions.
  • PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates extracting text, images, and regions directly from its PDF viewer based on  user selections.
  • Syncfusion WinForms PDF Viewer (part of Syncfusion Essential Studio Enterprise) lets you retrieve user-selected PDF text and areas via the viewer.

DevExpress WinForms 25.2は、アプリケーションを離れずにAIサービスの切り替えや出力の比較を簡単に実現

DevExpress WinForms is a comprehensive suite of 190+ UI controls and development tools designed for building high-performance desktop applications. It offers a broad array of customizable controls, from data grids and ribbon interfaces to advanced charts, maps, and diagramming components. This empowers developers to rapidly create functionally rich applications, while adhering to accessibility guidelines and touch-enabled technology for modern Windows environments.

The DevExpress WinForms 25.2 update introduces multi-provider support in the AI Chat Control, allowing developers to integrate several AI services into one application. This enables advanced use cases such as side-by-side comparison of responses from different AI models, concurrent sessions with independent chat histories, and dynamic switching between providers during runtime. It’s especially useful in environments where evaluating model performance or offering user choice is essential, such as customer support tools, research platforms, or development sandboxes.

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.
