Syncfusion Essential Studio JavaScript 2026 Volume 2 (34.1.29)Version majeure6 juil. 2026
Fonctionnalités
  • Common
    • Theme improvements:
      • The theming experience has been enhanced to provide a more modular and streamlined approach. Updated theme packages offer both consolidated and control-level styles, with dedicated entry points (index.css/index.scss) that automatically resolve dependencies.
      • The theming system has been upgraded to the latest Sass version 1.100.0, improving compatibility and providing a more consistent styling workflow across applications. SCSS styling is now standardized through centralized theme packages. SCSS files are no longer supported within individual component packages or the EJ2 combined package, enabling a more structured and maintainable approach to styling.
    • Production-ready component - The following component has been developed to meet industry standards and is now marked as production-ready for JavaScript:
      • Sankey Diagram: A powerful visualization tool for understanding flows and relationships within complex systems. It uses interconnected nodes and weighted links to clearly show how quantities move and transform across stages.
  • AI AssistView
    • Regenerate responses with navigation - The AI AssistView supports response regeneration, generating multiple alternative responses for a single prompt. Navigation arrows enable seamless browsing between generated responses without re-entering the prompt, enhancing exploration of different AI-generated solutions and reducing redundant prompt submissions.
    • Text-to-speech for responses - The integrated text-to-speech functionality speaks AI-generated responses hands-free, enabling developers to utilize AI-generated content while multitasking.
    • Generative UI with interactive tools - This feature enables generative UI, allowing interactive UI tools to be dynamically generated directly within AI responses. By configuring an appropriate system prompt, the AI can invoke registered tools, seamlessly integrating dynamic and interactive UI elements into responses.
    • AI chain-of-thoughts - The AI AssistView now displays the AI's chain-of-thought process before generating responses. It provides transparency into the AI model's reasoning steps, helping explain how conclusions were reached and enabling verification of the logical flow of AI-generated solutions.
  • Charts
    • Inline DateTime and number formatting in tooltip - Inline DateTime and number formatting within tooltip format strings enables values to be displayed more clearly and readably, such as formatting dates (MMM yyyy, MM:yy) and numbers (n2, c2, n0). This handles invalid formats or values without affecting rendering or template behavior.
  • Accumulation Chart
    • Nested donut (multi-level) - The multi-series pie chart displays multiple datasets as concentric rings within a single chart. This makes it easier to compare data and understand hierarchical relationships. Cross-series legend grouping with the mappingKey feature allows similar categories to be combined into a single legend item, enabling unified interaction across all matching slices. Each series operates independently, supporting tooltips, data labels, highlighting, and selection.
  • Stock Chart
    • Indicator events - Indicator events in Stock Charts enable users to detect and control add and remove operations triggered through the built-in toolbar. The before indicator change event allows canceling an indicator mutation before it is applied, while the indicator changed event is triggered after a successful indicator update.
  • Range Navigator
    • New series types - Range Navigator now supports Spline, SplineArea, and Column series types, expanding the visualization options for range-based data selection. Spline displays smoother trend lines, SplineArea emphasizes variations over a continuous range, and Column represents values as distinct vertical bars within the navigator.
  • DataGrid
    • DOM virtualization - Efficiently handles large datasets by rendering only the visible rows with a buffer. This reduces memory usage and ensures smooth scrolling.
    • Cell edits - The DataGrid provides a seamless inline editing experience. In addition to row-level editing, users can update individual cell values directly within the grid, with support for programmatic control.
    • Undo and redo for batch editing - This feature allows users to undo and redo batch editing, helping them correct mistakes quickly for a more reliable editing experience.
    • Show or hide columns with immediate mode - Columns can be shown or hidden dynamically with immediate mode, improving flexibility in data presentation.
    • Excel and checkbox filters with immediate mode - Filtering actions are now applied instantly without additional confirmation when using immediate mode, making data exploration faster and more intuitive.
  • Pivot Table
    • Built-in CRUD operations for seamless data management - The Syncfusion Pivot Table now supports native create, read, update, and delete (CRUD) operations with configurable, server-side controller endpoints. This enables efficient data editing directly within the pivot table, simplifies back-end integration, and eliminates the need for custom CRUD implementations. It is ideal for applications that require dynamic data updates and real-time synchronization.
    • Advanced top and bottom value filtering - Gain deeper insights with Top N and Bottom N filtering in pivot tables. This feature, available through both APIs and the runtime UI, allows users to filter and analyze high-performing or low-performing data points quickly. It enhances decision-making by helping users focus on the most critical values in large datasets.
    • Append current selection to existing filters - Improve filtering efficiency with incremental, Excel-like filtering capabilities. Users can now add the current selection to existing filters without clearing previously applied conditions. This makes multi-member filtering more intuitive and significantly enhances interactive data exploration.
    • Percentage of running totals aggregation type - The Pivot Table now supports percentage of running totals as an aggregation type. It allows users to view cumulative values as percentages, making it easier to analyze trends, measure contribution over time, and understand data progression.
    • Repeat item labels in classic pivot table layout - Enhanced readability and reporting clarity with repeating row item labels in a classic pivot table layout. They provide consistent formatting across the UI and exported reports, making it easier to interpret large and complex datasets in both digital and printed formats.
Syncfusion Essential Studio JavaScript 2026 Volume 1 SP1 (33.2.15)23 juin 2026
Fonctionnalités
  • Chat UI
    • Introduced a new method prependMessages to better support loading earlier conversations and improving chat continuity.
      • prependMessages – Prepends messages to the beginning of the Chat UI conversation area. This method inserts the specified messages either as messages[] or MessageModel[] as the first entries in the chat, making it ideal for loading historical messages when users scroll over the chat or reopen previous conversations.
  • Chip
    • Provided drag-and-drop functionality to rearrange chips and move them between containers. To enable drag and drop, set allowDragAndDrop to true.
  • PDF Viewer
    • Annotation Comment Filter - Introduced annotation filter support in the EJ2 PDF Viewer, enabling users to efficiently manage and view annotations by applying filters based on specific criteria. The filter options can be accessed through the filter icon in the comments panel, allowing users to display only the annotations that match their requirements.
    • Ink Eraser - Introduced ink eraser support in the EJ2 PDF Viewer, allowing users to selectively remove or correct portions of freehand ink annotations drawn on a PDF document. This feature enhances annotation flexibility by enabling precise editing of ink strokes for improved accuracy and usability.

This feature enhances chart readability and data clarity by enabling developers to annotate series without relying on separate legend elements. Labels support customization for alignment, formatting, and visibility control per series.
    • Legend templates - The Charts component now supports custom legend item templates, enabling developers to render custom HTML content for each legend entry. Custom templates are configured through the template property in legendSettings, allowing icons, formatted text, styled indicators, and other HTML elements to be displayed in place of default legend items. The template customization is applied per series, enabling consistent visual treatment across multiple series. This feature is fully backward compatible and does not introduce breaking changes to existing legend rendering behavior.

    • Visio file format (.vsdx) - Enabled the parsing and rendering of a Visio diagram (.vsdx) within the Syncfusion diagram canvas, as well as the modification and subsequent serialization of diagram content back into the Visio format (.vsdx). The implementation provides limited Visio compatibility, focusing on core elements such as nodes (basic shapes, flow shapes and group), connectors, ports, and annotations.
  • Gantt Chart
    • Predecessor offset validation - Predecessor offsets are now validated during load time in addition to CRUD operations. This enhancement ensures dependency chains reflect the correct offset values from the initial load, providing more accurate scheduling without manual recalculation.
    • Timeline view range - The visible timeline range can now be set independently of project scheduling dates, allowing the view to be expanded or restricted for focused planning and tracking.
  • Data Grid

        • Same page: All Pivot Tables are placed on a single PDF page, with an option to add blank space between them.
        • New page: Each Pivot Table is placed on its own PDF page.
      • Template-based exporting - Pivot Tables can now be exported with additional elements, such as hyperlinks and images, enabling richer, template-driven PDF layouts.
      • UI-replicated exporting - A Pivot Table exported to PDF now closely matches the on-screen version, including its:
        • Cell background colors.
        • Font styles and colors.
        • Row heights.
        • Visual appearance.
      • Advanced styling options - PDF cell styles can now be customized using theming, conditional formatting, and export events such as pdfQueryCellInfo and pdfHeaderQueryCellInfo.
      • Headers and footers - Headers and footers can now include branding details, metadata, time stamps, or report titles. These additions help present important information clearly in the exported PDF.
      • Custom aggregates and date formats - Custom formulas and localized date formats ensure accurate data representation in exported documents.
      • Cell and row spanning - Merged cells are now preserved during PDF export, improving layout accuracy in complex Pivot Table structures.
      • Custom data source binding - Pivot values can now be modified programmatically before exporting, enabling dynamic or scenario-based report generation.
  • Rich Text Editor
    • Table cell properties - The Rich Text Editor now supports table cell properties including width, height, cell padding, background color, vertical and horizontal alignment, border width, style, and color. These properties can be applied through the quick toolbar.
    • Table, row, and column selection - Table, row, and column selection can now be performed by clicking selection icons that appear on hover. This improves table editing operations in larger documents.
    • Image wrap - Images inserted into editor content now support text wrapping modes (left wrap, right wrap). These image wrap options can be applied using the quick toolbar.
    • Multiple image paste - Multiple images can now be pasted or dropped simultaneously from the local file browser, accelerating content creation by inserting many images at once.
  • Tree Grid
    • Seamless virtual scrolling - The Tree Grid's virtual scrolling has been upgraded to deliver a smooth, lag-free experience. Rows and columns continue to render only when visible in the viewport, but transitions remain fluid even during rapid navigation.
