SmartClient 14.1は、サーバーロジックやパフォーマンスに影響を及ぼすことなく、親ノードを表示したままにすることで、JavaScriptアプリの大規模なデータセットフィルタリングを改善

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.

四角形の注釈を使用すると、ユーザーはPDFにマークアップできるため、レビュー、承認、共同編集がより効果的かつ視覚的に明確化

Rectangle annotations in PDF viewer components enable users to highlight, mark, or comment on specific areas within a PDF document by drawing rectangular shapes. This feature is commonly used for reviewing documents, collaborating on content, or emphasizing sections in technical or legal workflows. It enhances user interactivity within the viewer, allowing for visual references and context-specific notes without altering the original document content.

Several React PDF viewer controls offer rectangle annotations including:

Document Solutions for PDF by MESCIUS provides rectangle annotations as part of its comprehensive annotation API, supporting precise placement and customization.

This gives developers the flexibility to adapt the layout and behavior of CardView to meet specific application requirements.
