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.
