Optimisez les grandes grilles de données avec le défilement virtuel

Décembre 17, 2025
Affichez uniquement ce que les utilisateurs voient pour maximiser la vitesse, réduire la consommation de mémoire et maintenir des interactions en grille fluides à n’importe quelle échelle.

Virtual scroll support in a grid component is a rendering strategy that displays only the rows and columns currently visible in the viewport while dynamically loading and unloading data as the user scrolls. It minimizes DOM size and memory usage by avoiding the creation of off-screen elements, which improves rendering speed, reduces layout thrashing, and maintains smooth interaction even with very large datasets. This approach enables grids to handle millions of records efficiently without requiring pagination, lowers CPU and GPU load, and delivers consistent performance across a wide range of devices.

Several React grid controls offer virtual scroll capability including:

  • DevExtreme React Data Grid (part of DevExtreme Complete by DevExpress) lets you render only visible records offering excellent performance for displaying thousands of data rows.
  • KendoReact Data Grid (part of KendoReact by Telerik) allows you to virtualize grid content for rapid scrolling and reduced DOM overhead with large datasets.
  • Wijmo React DataGrid (FlexGrid) (part of Wijmo by MESCIUS) facilitates virtual scrolling that loads data on demand, minimizing rendering work and preserving fluid navigation.
  • Infragistics Ignite UI for React Data Grid (part of Infragistics Ignite UI) enables row and column virtualization to significantly boost performance for large datasets.

ComponentOne Studio Enterprise 2025 v2 optimise vos applications WPF grâce à des capacités de mappage de contours et de visualisation de gradients haute performance.

ComponentOne Studio Enterprise is a comprehensive suite of .NET UI controls developed by MESCIUS (formerly GrapeCity) designed for building rich, interactive desktop, web, and mobile applications. It provides developers with a broad range of tools and components-including data grids, charts, reports, input controls, and advanced data visualization features-for platforms such as WinForms, WPF, ASP.NET Core, Blazor, WinUI, and .NET MAUI. The suite emphasizes performance, flexibility, and ease of integration, helping teams create consistent, feature-rich user experiences across multiple application types while maintaining a unified development approach.

The ComponentOne Studio Enterprise 2025 v2 update introduces 2D Contour Charts in FlexChart for WPF, allowing developers to represent three-dimensional data on a two-dimensional surface through contour lines or shaded bands that highlight areas of equal value. This capability delivers a clear visual understanding of gradients, surface characteristics, and other continuous data patterns. With support for multiple contour types, customizable contour levels, and flexible gradient color palettes, developers gain precise control over how value transitions are presented. These enhancements make the WPF contour chart well suited for scientific and engineering analysis, elevation and surface mapping, and any application that requires accurate comparison of value distribution across two variables.

ActiveReportsJS v6.0 introduit un mode de conception basé sur cellules pour des mises en page plus précises et une structure d’exportation Excel améliorée.

ActiveReportsJS by MESCIUS is a JavaScript reporting toolkit that allows developers to design and embed interactive reports within web applications. It includes a standalone report designer for building reports visually and a JavaScript report viewer component that integrates with web frameworks such as React or vanilla JavaScript. The toolkit supports a range of data visualization options and export formats, helping developers deliver rich, interactive reporting capabilities in the browser.

The ActiveReportsJS v6.0 update introduces a new cell-based layout mode that provides precise control over the alignment and structure of report elements using a grid of cells. This layout mirrors the structure of spreadsheets, making it particularly effective for generating reports intended for export to Microsoft Excel. It helps minimize layout inconsistencies and fragmented cells, ensuring a clean and predictable structure for exported files. Developers benefit from a more consistent and data-oriented layout approach, especially in scenarios where structural accuracy is critical.
