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.

DevExpress WPF is a powerful suite of controls that enhances your WPF development toolkit.

It is a simple yet effective way to enhance usability in complex applications, particularly those that rely on dynamic side panels or menus. This new functionality brings a modern and intuitive interaction model to WPF-based interfaces, aligning with common user expectations.

パラメータ付きレポートをフィルタリングしてカスタマイズ

1月 9, 2026

動的フィルタリングとユーザー定義条件を適用し、特定のシナリオに合わせたより関連性が高く正確かつ実行可能なレポートを提供

Report parameters allow users to customize and control how data is displayed by filtering results or supplying specific values at runtime. This enables more personalized, relevant reporting without the need to create multiple versions of the same report. By using parameters, organizations can improve data accuracy, improve report management, and help users to explore insights independently. Common use cases include filtering reports by date range, region, department, or product, setting thresholds or targets for performance analysis, and dynamically updating dashboards based on user-selected criteria.

Several .NET reporting components include support for parameters:

Telerik Reporting facilitates parameterized reporting to customize data views, reuse reports efficiently, and support interactive decision-making for diverse audiences.
DevExpress Reporting lets you define parameters to filter data, personalize layouts, and deliver interactive, context-aware reports across applications and dashboards.
List & Label Enterprise Reporting Edition by combit lets developers use parameters to tailor output and reduce duplication.
Stimulsoft Reports.NET allows runtime parameters for dynamic filtering, user-driven input, and adaptable reports that respond instantly to changing business requirements.
