WinFormsアプリケーションでPDFを直接閲覧、作成、検索、印刷しやすくし、一貫性のある信頼性の高いドキュメントプロセスをサポート

PDF reading and writing features form a core part of modern PDF components, allowing applications to view, generate, edit, and share PDF documents consistently across platforms. These capabilities cover common tasks such as displaying and searching documents, as well as creating and exporting PDFs programmatically with reliable rendering and standards compliance.

Common features include:

  • Creating PDFs allows applications to generate new PDF documents from code, data, or templates, supporting structured content, formatting, and metadata.
  • Printing/Saving to PDF enables users or systems to output documents to PDF format for sharing or archiving, with control over layout and print settings.
  • Printing PDFs to a printer provides direct printing capabilities, allowing PDF documents to be sent to physical printers with control over output settings.
  • Localization ensures PDF content, UI elements, and formatting adapt to different languages and regional conventions.
  • Right to Left (RTL) support provides correct layout and text flow for languages such as Arabic and Hebrew, ensuring accurate reading and presentation.
  • Searching text allows users to quickly find words or phrases within a document, improving navigation and usability for large or complex PDFs.
  • PDF Readers/PDF Viewers deliver accurate on-screen rendering of PDF files, supporting navigation, zooming, and page interaction.
  • Saving a PDF to a stream enables applications to write PDF output directly to memory or network streams, supporting efficient storage, transmission, and integration with external systems.

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.
