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.
• Syncfusion React Data Grid (part of Syncfusion Essential Studio Enterprise) lets you apply flexible aggregation to grids, displaying totals and averages.

Text, numeric, and boolean data editor components for JavaScript provide the fundamental building blocks for capturing and validating user input in web applications. These editors are designed to handle a wide range of data types and interaction patterns, helping developers present consistent, accessible, and predictable input experiences across forms, grids, and dialogs while integrating cleanly with application logic and data models.

Common editors include:

• Masked Input Text Box restricts text entry to a defined format, such as phone numbers, dates, or identification codes, ensuring data is captured in a consistent and expected structure.
• Numeric Spin allows users to enter numeric values using direct input or increment and decrement controls, often supporting constraints such as minimums, maximums, and step values.
• Button Editor combines a text field with one or more embedded buttons to trigger actions such as lookups, dialogs, or calculations related to the entered value.
• Checkbox represents boolean values using a simple on or off state, commonly used for options, preferences, and feature flags.
• Text Box provides free-form text input for strings, supporting features such as validation, placeholders, and length limits.
• Radio Group presents a set of mutually exclusive options, allowing users to select a single value from a predefined list.
• Toggle Switch offers a modern alternative to checkboxes for boolean input, visually emphasizing the enabled or disabled state.
• RTF Editor supports rich text formatting, enabling users to enter styled content such as bold text, lists, and links while maintaining structured output.
• Token Box manages multiple discrete values within a single field, often used for tags, email addresses, or selected items from a data source.
