Garanta a entrada de dados válida com grupos de opções

Dezembro 19, 2025
Use grupos de opções de controle intuitivos em seus aplicativos JavaScript para permitir a seleção de um valor único em um conjunto de dados predefinido.

A radio group in data editing refers to a set of mutually exclusive options presented as selectable buttons, where only one option can be active at a time. It is typically used in user interfaces to enforce a single selection from a predefined set of values, which helps reduce input errors and ensures data consistency. By visually grouping related choices and clearly indicating the selected value, a radio group simplifies decision-making for users and speeds up data entry. This control is especially useful in forms and configuration settings where a user must choose one valid option from several possibilities.

Several JavaScript data editor collections provide support for radio groups, including:

  • DevExtreme Angular Data Editors (part of DevExtreme Complete by DevExpress) lets you create radio groups with custom layouts, dynamic data binding, and intuitive selection.
  • KendoReact Data Editors (part of KendoReact by Telerik) provides fully accessible radio group components with flexible styling options and easy integration into React apps.
  • Infragistics Ignite UI for Angular Data Editors (part of Infragistics Ignite UI) offers configurable radio group functionality with straight-forward data mapping.
  • Syncfusion JavaScript Data Editors (part of Syncfusion Essential Studio Enterprise) includes customizable radio group controls for smooth interaction across major web frameworks.

Possibilite a colaboração de planilhas em tempo real

Dezembro 19, 2025
O SpreadJS 19 adiciona suporte para trabalho colaborativo com um novo complemento de servidor que permite que múltiplos usuários editem a mesma planilha simultaneamente.

SpreadJS is a JavaScript spreadsheet and data visualization component built to deliver Excel-compatible functionality within web applications. It provides a flexible, high-performance interface for displaying and manipulating tabular data, supporting advanced features such as formulas, pivot tables, charts, conditional formatting, and data binding. SpreadJS integrates smoothly with popular frameworks like React, Angular, and Vue, and includes robust import and export capabilities for Microsoft Excel files. It is commonly used in enterprise applications where users need a responsive, interactive spreadsheet experience directly in the browser.

The SpreadJS 19.0.0 update introduces a new Collaboration Server Add‑on that enables real‑time, multi‑user editing of the same spreadsheet within web applications by integrating the collaboration framework and server infrastructure directly into SpreadJS. This add‑on lets developers build functionality where multiple clients see and apply changes instantly to workbook data with consistent state across users, supports conflict‑free concurrent edits using Operational Transformation logic, and includes features such as live user presence and permission controls.

To see a full list of what's new in 19.0.0, see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.

Mostre o progresso com gráficos orientados a metas

Dezembro 18, 2025
Compare orçamento, previsão e valores reais em um gráfico compacto para identificar instantaneamente as variações e acompanhar o progresso em direção às metas com clareza.

Bullet charts are goal-oriented visualizations that compare actual performance against targets and benchmarks such as budget and forecast values in a single, easy-to-read view. They offer a clear alternative to gauges and meters by showing progress toward goals while making variances and shortfalls immediately obvious. By presenting multiple reference points together, bullet charts help stakeholders interpret performance quickly and consistently across metrics. Common use cases include financial reporting, sales and margin tracking, KPI dashboards, operational scorecards, and executive summaries where fast, reliable comparisons support better decision-making.

Several JavaScript chart controls offer bullet chart support including:

  • Highcharts Core by Highsoft lets you build bullet charts comparing performance against targets with interactive tooltips, responsive layouts, and customization.
  • KendoReact Charts (part of KendoReact by Telerik) allows you to render bullet charts, emphasizing KPIs, qualitative ranges, and accessibility-friendly components.
  • amCharts 5: Charts facilitates modern bullet charts with animated transitions, flexible axes, precise benchmarks, and theming for data-driven dashboards applications.
  • Syncfusion JavaScript Charts (part of Syncfusion Essential Studio Enterprise) lets you create bullet charts showcasing targets, ranges, and actuals.

Otimize grandes grades de dados com rolagem virtual

Dezembro 17, 2025
Renderize apenas o que os usuários veem para maximizar a velocidade, reduzir o uso de memória e manter as interações suaves na grade em qualquer escala.

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.

Adicione clareza aos gráficos com transições animadas

Dezembro 15, 2025
Os gráficos Web Components com animações facilitam a visualização das alterações de dados e ajudam os usuários a manter o foco, mesmo com visuais complexos.

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.
