Improve PDF Navigation in React Applications

August 19, 2025
With thumbnail navigation users can visually locate and browse to specific pages of a PDF at speed without having to scroll or use search functions.

Thumbnail navigation is a feature often found in a PDF viewer that displays miniature representations of each page of the PDF file, typically in a side panel or dedicated section, that users can scroll through and navigate to the desired page by clicking on the relevant preview image. This functionality assists with identifying content layout and structure at a glance. By allowing users to visually scan through and select a specific page it simplifies the process of locating content at speed, especially in long or detailed files, and without having to scroll or use search functions.

Several React PDF viewer components offer thumbnail navigation, including:

  • Wijmo PDFViewer (part of Wijmo by MESCIUS) lets users preview pages as thumbnails, enabling efficient PDF navigation and quick access to specific content in React apps.
  • PrizmDoc Viewer (part of PrizmDoc by Accusoft) also supports React and facilitates fast page access with thumbnail previews, helping users identify and jump to relevant sections.
  • Syncfusion PDF Viewer (part of Syncfusion Essential Studio Enterprise) equips React apps with a lightweight PDF viewing component that supports quick navigation via thumbnails.

Apply LAMBDA Functions Directly to Cell Selections

August 15, 2025
SpreadJS 18.2 adds new Transform command to execute LAMBDA formulas over selected cells and replace them in one step.

SpreadJS is a high-performance JavaScript spreadsheet and data presentation component designed for enterprise web applications. It enables developers to deliver Excel-like functionality directly within their web solutions, providing advanced features such as data binding, complex calculations, pivot tables, charts, and extensive formatting options. Fully compatible with modern JavaScript frameworks like React, Angular, and Vue, SpreadJS allows seamless integration and customization, empowering development teams to create interactive, data-driven user experiences without relying on external spreadsheet applications.

The SpreadJS 18.2 adds a new Transform command which enables you to apply LAMBDA functions directly to a selected range of cells and replace the original content with calculated results. This simplifies data transformations - whether mapping, filtering, or reshaping - into a clean, single-step process. With this feature, you can select any range and apply a custom LAMBDA formula - for example, converting units, adjusting values, or formatting entries - and have SpreadJS overwrite the selection with the computed results immediately. This removes manual steps like inserting formulas in separate cells, copying values, or pasting back as values. This feature integrates with SpreadJS’s existing LAMBDA capabilities to offer more interactive and efficient spreadsheet manipulation.

To see a full list of what's new in 18.2, 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.

Preserve Tree Context in Filtered Views

August 8, 2025
SmartClient 14.1 improves large dataset filtering in JavaScript apps by keeping parent nodes visible, with no server logic or performance hit.

SmartClient is a powerful JavaScript component suite compatible with React, Vue, Angular, and more, designed for building large-scale, high-performance web apps. It offers advanced UI components, dynamic data handling, customizable grids, and responsive design. Ideal for enterprise use cases like financial analytics and real-time reporting, SmartClient supports seamless backend integration and delivers optimized performance and scalability.

SmartClient has enhanced hierarchical data handling with the included KeepParentsOnFilter setting, ensuring that parent nodes remain visible in filtered views, even when data is loaded dynamically. It loads "skeleton branches" via a complex client-driven algorithm, automatically managed by SmartClient, to maintain high performance without preloading the entire tree, meaning it doesn't require server-side programming. This is particularly useful in large datasets with load-on-demand trees, as it allows users to maintain full visibility into the structure of filtered results without losing context. By preserving the hierarchical path to matching records, this feature improves usability and clarity in tree-based components, especially in applications where understanding the parent-child relationship is critical.

SmartClient is licensed per developer and is available as both perpetual and subscription licenses. Product updates and technical support is also available. See our SmartClient licensing page for full details.
