Optimieren großer Datenraster mit virtuellem Scrolling

Dezember 17, 2025
Reduzieren Sie die Darstellung auf das, was die Nutzer sehen, um die Geschwindigkeit zu maximieren, den Speicherverbrauch zu reduzieren und die Interaktionen im Raster in jedem Maßstab möglichst flüssig zu gestalten.

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.

Übersichtliche Diagramme mit animierten Übergängen

Dezember 15, 2025
Web Components Charts mit flüssigen Animationen machen Datenänderungen leichter sichtbar und helfen den Nutzern, selbst bei komplexen Visualisierungen konzentriert zu bleiben.

Animation in a Web Components Chart control refers to the visual transitions applied to chart elements as data is rendered, updated, or interacted with. It enhances the user experience by making changes in the data more perceptible and easier to follow, particularly when dealing with dynamic or real-time datasets. For developers, animation helps improve data readability and provides a more engaging and polished interface, especially when charts are updated frequently or involve user interaction. It also makes it easier for users to track what’s changed in the chart, even when the visuals are complex.

Several Web Components chart controls offer animation including:

  • Wijmo Web Components Chart (part of Wijmo Enterprise by MESCIUS) lets you animate chart updates smoothly, helping users clearly follow dynamic data transitions.
  • jQWidgets Chart facilitates animated rendering and transitions, making it easier to present changing data visually without overwhelming the user.
  • Ignite UI Web Components Chart (part of Infragistics Ignite UI) allows you to add refined animation effects, enhancing visual feedback during data changes.
  • ZingChart supports flexible animation options, enabling developers to create dynamic visualizations that respond intuitively to updates and user interaction.
