DevExpress Universal 25.2 integriert eine neue API, die es Apps ermöglicht, Benutzerabsichten zu interpretieren und Änderungen während der Laufzeit direkt auf Oberflächenkomponenten und die Logik anzuwenden.

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 25.2 integriert einen Ribbon Page Header Button, um die Navigationsfenster umzuschalten und so die vertraute Benutzeroberfläche von Microsoft Outlook widerzuspiegeln.

DevExpress WPF is a powerful suite of controls that enhances your WPF development toolkit. It offers data grids, ribbon menus, rich text editors, spreadsheets, charts, and more, all with beautiful themes and touch-friendly interfaces. DevExpress WPF helps you to build professional-looking, responsive applications that meet modern user expectations, saving you time and effort while adding polish and functionality.

The DevExpress WPF 25.2 update introduces support for a Page Header Button positioned directly in the ribbon’s page header area. This new UI element allows developers to replicate the toggle behavior seen in recent versions of Microsoft Outlook, where users can expand or collapse navigation panes with a single click. 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.

Filtern und Anpassen von Berichten mit Parametern

Januar 9, 2026
Wenden Sie eine dynamische Filterung und benutzerdefinierte Bedingungen an, um relevante, genaue und umsetzbare Berichte zu liefern, die auf bestimmte Szenarien zugeschnitten sind.

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.

Ermöglichen einer einfachen Datenbearbeitung mit Rasterformularen

Januar 9, 2026
Erstellen Sie schnelle Updates durch direktes Bearbeiten der Datensätze, ohne Verlassen der Datenansicht.

Forms in grids combine tabular data display with built-in form editing, allowing users to view and update records directly within the grid instead of switching to separate edit screens. This approach improves efficiency by keeping users in context, reducing navigation, and providing immediate validation and feedback. Forms in grids are commonly used in administrative dashboards, configuration screens, and data-heavy business applications where users need to edit multiple records quickly while maintaining visibility of related data.

Several .NET grid components enable form-based editing within grids, including:

  • DevExpress WinForms Data Grid (part of DevExpress WinForms) lets you embed forms within rows for fast editing and validation in complex application scenarios.
  • Telerik UI for WPF DataGrid (part of Telerik UI for WPF) allows you to combine grid-based forms with native styling for efficient in-place data editing.
  • Wisej.NET facilitates form-driven editing directly inside grids, enabling responsive web-like experiences with server-side logic for enterprise applications and rapid development.
  • NOV Grid for .NET allows you to manage complex datasets using integrated grid forms that support validation, customization, and scalability.
