ASP.NET Core、MVC、BlazorのTelerik UIでは、ユーザーが簡単なテキストプロンプトでデータの形を変え、ナビゲーションし、エクスポート可能

Telerik UI for ASP.NET Core, MVC, and Blazor are component libraries for building modern web apps with .NET. Each provides a rich set of customizable UI elements, like grids, charts, and forms, tailored to its respective framework, helping developers create responsive, interactive, and accessible user interfaces.

The latest update to the Telerik UI DataGrid introduces AI-driven controls that respond to natural-language prompts, making it easier for users to work with complex datasets. Users can now reorder, resize, and toggle column visibility just by describing what they want. Pagination, row selection, and data export to Excel, PDF, or CSV formats can also be handled through conversational input, reducing clicks and improving accessibility for both technical and non-technical users.

Telerik UI for ASP.NET Core, UI for MVC, and UI for Blazor are all licensed per developer and have two licensing models: an annual Subscription License and a Perpetual License. The Subscription License 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. See our Telerik UI for ASP.NET Core, Telerik UI for ASP.NET MVC or Telerik UI for Blazor licensing pages for full details.

Telerik UI for ASP.NET Core, Telerik UI for ASP.NET MVC and Telerik UI for Blazor are available to buy individually or as part of the following products:

DevExpress Universal 25.2は、アプリがユーザーの意図を解釈し、実行時にUIコンポーネントやロジックに変更を直接適用できる新しいAPIを追加

DevExpress Universal is a comprehensive suite of UI components and developer tools that supports the creation of feature-rich applications across web, desktop, and mobile platforms, including .NET, JavaScript, Blazor, ASP.NET, WinForms, WPF, and MAUI. It focuses on delivering consistent user interfaces, advanced data visualization, reporting, dashboards, and productivity features that help teams design, build, and maintain complex applications using a unified set of technologies and patterns.

DevExpress Universal v25.2 introduces AI Tool Calling (Natural Language Control for UI Components), a cross-platform feature that extends Microsoft.Extensions.AI tool-calling to enable natural-language interaction with application UI and logic. Developers can expose UI components, ViewModels, and business services as AI-invokable tools, grouped into dynamic toolsets that adapt to the application’s current context. When users interact through the DevExpress AI Chat Control, the language model interprets their request, selects the appropriate tool, resolves the target instance, and executes the action in real time, making applications easier to use while giving developers full control over what the AI can see and do.

DevExpress Universal is licensed per developer and is available as a Perpetual License with a 12 month support and maintenance subscription. See our DevExpress Universal licensing page for full details.

Syncfusion Essential Studio Spreadsheet Editor SDKは、数字、日付、カスタムリストの系列埋め込みを追加し、ユーザーのデータの拡張をさらに高速化

Syncfusion Essential Studio Spreadsheet Editor SDK is a library that lets developers embed spreadsheet functionality into web and desktop applications without requiring Microsoft Excel. It supports editing, formatting, and data analysis features such as cross sheet formula calculation, data binding to local and remote sources including JSON and REST, conditional cell styling, charts, data validation, worksheet protection, and workbook permissions. Available across frameworks including Blazor, React, Angular, Vue, JavaScript, ASP.NET Core and MVC, WPF, WinForms, and UWP, it helps teams deliver a familiar spreadsheet experience for use cases like reporting, budgeting, forecasting, and operational data entry directly within their applications.

The Syncfusion Essential Studio Spreadsheet Editor SDK 2025 Volume 4 update adds Blazor Autofill series support, allowing users to quickly extend numeric, date-based, and custom list patterns across cells in a predictable manner. This capability preserves existing cell formatting where applicable and provides flexible behavior for copying values versus generating sequences, reducing the need for custom implementation logic. As a result, developers can deliver more intuitive, Excel-like spreadsheet experiences with improved data consistency, reduced input errors, and faster interaction for end users.

Syncfusion Essential Studio DOCX Editor SDKは非同期ドキュメント読み込み機能を追加し、リモートデータアクセス時の操作をよりスムーズに

The Syncfusion DOCX Editor SDK provides a Microsoft Word inspired WYSIWYG editor that lets developers add Word document drafting, editing, and report generation to web and .NET desktop applications. It supports rich formatting with styles, tables, images, lists, and track changes, helping users create consistent, professional documents. With import and export support and a familiar interface, it reduces development effort and improves productivity for use cases like reporting, proposals, contracts, and document processes in business applications.

The Syncfusion Essential Studio DOCX Editor SDK 2025 Volume 4 update introduces asynchronous document loading for the Blazor DOCX Editor. This improves application responsiveness by preventing the user interface from blocking while documents are fetched and opened. By allowing document loading to occur in the background, developers can ensure the main thread remains available for user interactions, resulting in smoother navigation and more predictable behavior during network or file access delays. This enhancement helps create more responsive, user friendly applications, particularly when working with large documents or remote data sources.
