Dê destaque a insights-chave com a formatação condicional

Abril 16, 2026
Melhore a visibilidade dos dados com a formatação condicional em grades, usando indicações para destacar padrões e anomalias importantes.

Conditional formatting in grids automatically applies visual styles such as colors or icons based on defined rules, making it easier to interpret large datasets at a glance. It improves readability, highlights patterns and outliers, and supports faster, more informed decision making by surfacing key insights in real time. Common use cases include flagging budget issues in financial reports, emphasizing top performing sales data, monitoring KPIs, and drawing attention to errors or critical statuses in operational tools.

Several JavaScript grid controls offer conditional formatting, including:

  • KendoReact Data Grid (part of KendoReactby Telerik) lets you apply conditional formatting rules to style cells, highlighting trends, outliers, and key values for better insights.
  • FusionGrid by FusionCharts facilitates real time conditional formatting in large datasets, helping users quickly spot trends, exceptions, and performance indicators.
  • Handsontable by Handsoncode allows you to visually emphasize important data using conditional formatting, improving readability and enabling faster identification of patterns.
  • ZingGrid lets you customize conditional formatting rules to automatically highlight critical data points, enhancing usability and supporting faster, more informed decision making.

Previna edições indesejadas na grade

Abril 9, 2026
Grades JavaScript com colunas somente leitura ajudam os desenvolvedores a proteger valores fixos enquanto tornam as regras de edição mais claras em toda a interface.

Read-only Columns are grid columns configured to display data without allowing users to edit the values directly in the interface. In a JavaScript grid control, this is typically used for fields that should remain fixed, such as calculated values, identifiers, audit data, or information controlled by business rules or backend processes. The main benefit is that it helps preserve data integrity while still making important information visible, reduces the risk of accidental changes, supports clearer editing workflows by distinguishing editable and non-editable fields, and makes it easier for developers to enforce validation and permission requirements consistently across the application.

Several JavaScript grid controls offer support for Read-only Columns including:

  • Highcharts Grid Pro lets you configure non-editable columns for protected values, helping preserve data integrity while keeping reference fields consistently visible.
  • Kendo UI Angular Grid allows you to control column editable status, keeping selected fields read-only to enforce rules and reduce accidental changes.
  • Wijmo React DataGrid (FlexGrid) facilitates read-only column scenarios through editing controls and events, supporting protected fields and condition-based restrictions.
  • DataGridXL allows you to set columns as read-only, preventing edits to protected data while preserving fast spreadsheet-like interaction.
  • Handsontable lets you lock selected grid cells from editing, preserving displayed values while still supporting sorting, filtering, validation, and spreadsheet-style navigation.
  • JSpreadsheet Pro lets you mark columns or cells as read-only, protecting fixed values while allowing editable data elsewhere.

Adicione recursos de QR a aplicativos corporativos

Abril 8, 2026
O Sencha Ext JS v8.0 adiciona leitura e geração de códigos QR integradas para simplificar o compartilhamento de dados e fluxos de trabalho móveis dentro de aplicativos Web complexos.

Sencha Ext JS is an enterprise-focused JavaScript framework for building complex, data-intensive web applications, particularly business software such as dashboards, admin systems, reporting tools, and other large-scale user interfaces. It provides a broad library of prebuilt components, including grids, charts, forms, layouts, and data handling features, along with supporting tools for theming, testing, and application development, which helps teams create consistent, cross-platform applications more efficiently. In practice, Ext JS is best known for its strong support for rich user interfaces and large datasets, making it a good fit for organisations that need robust, maintainable front-end applications rather than lightweight websites.

The Sencha Ext JS v8.0 update adds QR Code Reader/Generator functionality that lets developers generate and read QR codes directly within applications across both the Modern and Classic toolkits. It supports use cases such as payments, data sharing, contact exchange, calendar events, geolocation, phone and SMS, email, and Wi-Fi configurations, while also providing rendering options including SVG, Canvas, and PNG, plus image download, clipboard copy, preview, responsive sizing, customization, and input sanitization. The result is a built-in way to add QR code barcode capabilities to enterprise applications with broad format support and flexible configuration.

To see a full list of what's new in v8.0, see our release notes.

Sencha Ext JS is available in Pro, Enterprise and Ultimate editions, as Annual Subscription Licenses. See our Sencha Ext JS licensing page for full details.

Visualize dados geográficos em tempo real

Abril 1, 2026
Use visualizações de mapas para explorar dados geográficos, descobrir padrões e monitorar a atividade em tempo real em aplicativos e painéis modernos.

Map components allow developers to embed interactive, location-based data visualizations into applications and dashboards. By presenting data in a geographic context, they make it easier to identify patterns, monitor activity, and support faster decision-making. With features like real-time updates, data layering, and interactive navigation, maps are commonly used for tracking regional performance, visualizing logistics and routes, and monitoring live or spatial data within modern dashboards.

Several React UI suites provide map controls including:

  • DevExpress Dxperience lets you integrate interactive maps into dashboards, enabling geographic data visualization, region-based analysis, and real-time spatial insights.
  • Telerik DevCraft UI allows you to embed customizable map components, supporting geospatial data rendering, interactive navigation, and location-driven insights.
  • Infragistics Ignite UI facilitates high-performance geographic mapping, enabling real-time data plotting, layered visualizations, and rich interactivity for advanced analytics.
  • Syncfusion Essential Studio UI Component Suite lets you incorporate feature-rich maps, delivering scalable geospatial visualization, customizable layers, and intuitive exploration.
