Réutilisez des sections de rapports avec des sous-rapports flexibles

Janvier 14, 2026

Intégrez des rapports modulaires dans des mises en page maîtresses pour simplifier des scénarios complexes et réduire la logique dupliquée entre les sources de données.

Subreports allow independently maintained reports to be embedded within a master report, enabling a modular and flexible reporting design. Each Subreport can be created, maintained, and reused separately, while connecting to the master report through parameters that dynamically filter its data from a separate data source. This approach simplifies complex reporting scenarios, improves consistency, and reduces maintenance effort by avoiding duplicated logic. Common use cases include displaying detailed line items within summary reports, combining data from multiple databases, or reusing standardized sections such as invoices, audit details, or customer histories across multiple reports.

Several ASP.NET Core reporting controls offer support for subreports including:

DevExpress Reporting lets you embed reusable subreports, link multiple data sources via parameters, and manage complex report structures efficiently.
TX Text Control .NET Server for ASP.NET facilitates dynamic subreports for documents, enabling separate data sources and parameter-driven content reuse.
Telerik Reporting allows you to design modular subreports, pass contextual parameters, and combine independent data queries within reports securely.
FastReport .NET WEB lets you integrate flexible subreports, filter datasets through parameters, and reuse report components across web applications easily.

Accélérez le rendu avec la virtualisation en colonne

Janvier 14, 2026

DevExpress Blazor 25.2 ajoute la virtualisation des colonnes à la grille, à la liste arborescente et au tableau croisé dynamique, améliorant les performances en ne rendant que les colonnes visibles.

DevExpress Blazor (part of DevExpress ASP.NET and Blazor) helps you create high-impact user experiences for both Blazor Server and Blazor WebAssembly using C#. The Blazor UI Component Library ships with a comprehensive set of native components including a Grid, Pivot Table, Scheduler, Chart, Data Editors and Reporting.

The DevExpress Blazor 25.2 update introduces column virtualization to its Grid, TreeList and Pivot Table UI components, significantly enhancing performance for large datasets. When this feature is enabled, only the columns visible in the user's current viewport are rendered, reducing the Document Object Model (DOM) size and speeding up initial load times. This new approach can be combined with existing row virtualization, allowing both horizontal and vertical data to render efficiently, even in tables with hundreds of fields. Users can smoothly navigate across cells using scrollbars or keyboard shortcuts, maintaining a responsive and fluid experience throughout.

To see a full list of what's new in version 25.2, see our release notes.

DevExpress ASP.NET and Blazor is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. See our DevExpress ASP.NET and Blazor licensing page for full details.
