AIセマンティック検索でデータ検出が向上

3月 4, 2026
Telerik DevCraft 2026年第1四半期では、DataGridに自然言語SmartBox検索が追加され、複雑なデータセットをまたいだ文脈認識の結果が可能

DevCraft by Telerik is a comprehensive AI-powered suite of more than 1,250 UI components and development tools designed for building modern web, desktop, and mobile applications using .NET and JavaScript frameworks. It includes reporting and report management solutions, automated testing and mocking tools, and document processing libraries, as well as a wide range of professionally designed user interface controls from the Telerik and Kendo UI suites. DevCraft enables developers to create feature-rich, high-performance applications with consistent design and user experience, delivering enterprise-level, scalable, and maintainable software solutions.

The Telerik DevCraft 2026 Q1 update adds Semantic Search through a new unified SmartBox, making it easier for developers to build natural language search directly into the DataGrid. Instead of depending on exact keyword matches, the feature uses artificial intelligence (AI) to understand meaning and context. It can return relevant results across multiple columns and related fields, even if the user’s search terms do not exactly match the stored data. The SmartBox brings semantic search, filtering, and follow-up query refinement together in one interface. This reduces the need to write and maintain custom search logic, while making integration more straightforward. As a result, applications can deliver more accurate search results, help users find information faster, and make large or complex datasets easier to explore.

To see a full list of what's new in DevCraft 2026 Q1, see our release notes.

Telerik DevCraft is licensed per developer and has two licensing models: an annual Subscription License and a Perpetual License. The Subscription license provides access to the latest product updates, technical support, and exclusive benefits for a flat annual fee, and must be renewed to continue using the software. The Perpetual license is a one-time purchase granting access to the current released version and includes a one-year subscription for product updates and technical support. After this initial period, users can choose to renew the subscription element to continue receiving updates and support; otherwise, they may continue using the installed version available during their active subscription term but will forgo future updates and support.
