用智能重新渲染优化单元格更新

3月 13, 2024
Handsontable 14.2.0 现在使用记忆化（memoization）来防止在用户交互（如单元格编辑或滚动）后不必要的重新渲染。

Handsontable is a JavaScript library designed to help developers build interactive data grids into their web applications. Offering a familiar spreadsheet-like interface, it allows users to edit, sort, and filter data with ease. Highly customizable and compatible with popular frameworks like React and Angular, Handsontable empowers developers to build robust data manipulation features into their web applications.

Handsontable 14.2.0 improves cell re-rendering using the React wrapper. The wrapper now uses memoization to optimize performance during user interactions like cell editing or scrolling in the grid, allowing the wrapper to remember the previous state and only update the elements that have actually changed. This smarter approach results in a smoother and more stable experience in your Handsontable apps, especially for complex custom cell types.

To see a full list of what's new in version 14.2.0, see our release notes.

Handsontable is licensed per developer and is available as an Annual or Perpetual license with 1 year support and maintenance. See our Handsontable licensing page for full details.

实现 Angular 网格的服务器端排序

2月 21, 2024
通过高效的服务器端排序、优化性能和可扩展性来实现无缝数据处理，释放 Angular 网格的潜力。

Offloading sorting tasks to a server (known as remote server sorting or server-side sorting) enables large datasets to be handled efficiently without overwhelming the client. This minimizes data transmission and leads to snappier web applications. Moreover, server-side sorting boosts scalability by ensuring processing happens on the server, freeing up client resources. This translates to faster response times, especially for large datasets, making the user experience smoother. This approach empowers developers to build responsive and scalable web applications that excel at managing and presenting sorted data.

Several Angular grid controls offer sorting on the remote server, including:

  • Wijmo FlexGrid (part of Wijmo by MESCIUS) offers remote server sorting capabilities, enhancing grid responsiveness by delegating sorting tasks to the server side.
  • DevExtreme HTML5 JavaScript Data Grid (part of DevExtreme Complete by DevExpress) offers remote server sorting, boosting performance by offloading sorting to the server.
  • jQWidgets Grid (part of jQWidgets) optimizes data grid sorting with remote server support, ensuring efficient processing and enhancing overall performance in Web applications.
  • Ignite UI Angular Grid (part of Infragistics Ignite UI) streamlines grid sorting with remote server support, providing efficient processing for improved performance and scalability.
  • ZingGrid enhances user experience with remote sorting, allowing developers to implement efficient server-side sorting for improved performance in grid-based data presentations.
