ツールチップでグリッドデータにコンテキストを追加

2月 2, 2026
ツールチップを使って、グリッド内で直接説明、メタデータ、検証の詳細を提供し、ユーザーがデータから離れずに理解可能

Tooltips in grid components provide contextual information that appears when users hover over or focus on a cell, column header, or row. It offers a practical way to surface additional details such as full text for truncated values, validation messages, or explanatory metadata without overcrowding the grid layout. For data-heavy interfaces, this feature improves readability and usability by keeping the primary view concise while still making secondary information readily accessible when needed.

Several Blazor grid controls offer FEATURE including:

  • Telerik UI Blazor Data Grid (part of Telerik UI for Blazor) provides configurable tooltips for cells and headers and allows developers to control content, positioning, and display.
  • ComponentOne Blazor FlexGrid (part of ComponentOne Studio Blazor Edition by MESCIUS) offers tooltips that can be applied at the cell level, making it useful for showing full values.
  • Blazorise supports tooltips in grids by integrating its tooltip components with data tables, allowing developers to attach descriptive or dynamic content to cells.
  • Syncfusion Blazor DataGrid (part of Syncfusion Essential Studio Enterprise) includes integrated tooltip functionality that works alongside its column and cell customization features.

自然言語でデータグリッドを制御

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:

列仮想化でレンダリングを高速化

DevExpress Blazor 25.2は、グリッド、ツリーリスト、ピボットテーブルにカラム仮想化を追加し、可視列のみをレンダリングすることでパフォーマンスが向上

DevExpress Blazor (part of DevExpress ASP.NET and Blazor) helps you create high-impact user experiences for both Blazor Server and Blazor WebAssembly using C#. The Blazor UI Component Library ships with a comprehensive set of native components including a Grid, Pivot Table, Scheduler, Chart, Data Editors and Reporting.

The DevExpress Blazor 25.2 update introduces column virtualization to its Grid, TreeList and Pivot Table UI components, significantly enhancing performance for large datasets. When this feature is enabled, only the columns visible in the user's current viewport are rendered, reducing the Document Object Model (DOM) size and speeding up initial load times. This new approach can be combined with existing row virtualization, allowing both horizontal and vertical data to render efficiently, even in tables with hundreds of fields. Users can smoothly navigate across cells using scrollbars or keyboard shortcuts, maintaining a responsive and fluid experience throughout.

To see a full list of what's new in version 25.2, see our release notes.

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

AIプロンプトでアプリの挙動を制御

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.
