ドリルダウンサポートで文脈内でデータを探索

2月 23, 2026

グリッドインターフェース内で詳細記録に直接アクセスできるため、ユーザーはビューを切り替えたり文脈を失うことなく関連データを確認可能

Drill-down support in a grid component allows users to move from summarized data to more detailed records within the same interface, often by expanding rows or selecting linked values that reveal related data. Instead of navigating to a separate page or view, users can access underlying information directly in context. For developers, this reduces the need for additional navigation and simplifies the presentation of hierarchical or related datasets. It also makes it easier to analyze data step by step, helping users inspect specific records or relationships without losing their place in the overall dataset.

Several React grid controls support drill-down features including:

Wijmo React DataGrid (FlexGrid) (part of Wijmo by MESCIUS) lets you implement drill-down in grids through hierarchical row expansion and detail templates.
DevExtreme React Data Grid (part of DevExtreme Complete by DevExpress) allows you to present master-detail relationships within grids, revealing nested records dynamically.
Sencha Ext JS facilitates drill-down interactions in data grids by supporting expandable rows and structured access to related datasets.
ZingGrid lets you enable interactive row expansion and linked data views, helping users navigate underlying records directly within grids.

JavaScriptレポートに構造化ナビゲーションを追加

2月 16, 2026

JavaScriptアプリでレポートを設計する際に目次を取り入れ、セクションの構造化を明確にし、より速く直感的なナビゲーションが可能

A table of contents in a report is a structured list of sections and subsections that provides an organized overview of the document's content. It typically reflects the report's hierarchy and allows readers to navigate quickly to specific sections, either through page references in printed formats or clickable links in digital formats. This functionality improves usability by reducing the time required to locate information, supporting clearer document structure, and making complex or lengthy reports easier to understand and manage. For organizations that distribute detailed analytical or operational reports, a table of contents contributes to a more professional presentation and a more efficient review process.

Several JavaScript reporting components allow you to add a table of contents, including:

DevExpress Reporting provides a built-in table of contents control that can be bound to report elements, automatically generating entries based on defined heading levels and supporting interactive navigation in exported formats such as PDF and web previews.
ActiveReportsJS by MESCIUS includes a table of contents component that integrates with its JavaScript-based reporting engine, enabling developers to define document map nodes and create interactive, hierarchical navigation within browser-based report viewers.
Stimulsoft Reports.JS enables developers to create a configurable TOC using report bands, components, and bookmark functionality, with support for nested structures and interactive links in exported documents to improve navigation across complex reports.

自動グリッド計算でデータを要約

2月 11, 2026

合計、平均、最小値、最大値を自動計算するグリッド集約機能により、より迅速かつ情報に基づいた意思決定が可能

Aggregation in grids is the ability to automatically calculate summary values such as sums, averages, minimums, and maximums directly within tabular data views. By displaying these calculations alongside the underlying data, users can quickly understand trends, compare values, and identify outliers. This enables faster, more informed decision making. Typical use cases include showing total sales figures, calculating average performance metrics, tracking minimum and maximum thresholds, and summarizing financial, operational, or analytical data in real time within business applications.

Several React grid controls offer aggregation including:

DevExtreme React Data Grid (part of DevExtreme Complete) lets you calculate sums, averages, minimums, and maximums within grids.
KendoReact Data Grid Part of KendoReact by Telerik) allows you to summarize tabular data with built in aggregation, supporting totals and averages.
Infragistics Ignite UI for React Data Grid (part of Infragistics Ignite UI) facilitates grid aggregation, helping teams compare values and monitor thresholds.
