Control App Behavior with AI Prompts

January 13, 2026
DevExpress Universal 25.2 adds a new API that lets apps interpret user intent and apply changes directly to UI components and logic at runtime.

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.

Filter and Customize Reports with Parameters

January 9, 2026
Apply dynamic filtering and user-defined conditions to deliver more relevant, accurate, and actionable reports tailored to specific scenarios.

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.

Enable Easy Data Editing with Grid Forms

January 9, 2026
Make quick updates without leaving the data view by editing records directly in place.

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.
