React Row Grouping

The Ignite UI for React Data Table / Data Grid lets you group rows into a ‘sticky header’ Row Group. This is similar to the Group By feature in Microsoft Outlook, which is an easy way to visually group data based on your own criteria.

React Row Group-By Area Example

Group-By Area

Set IsGroupByAreaVisible property on the DataGrid to True, as shown in the example above, to the user interface. The group-by area allows users more options to group and sort columns without interact when interacting the DataGrid indirectly. Groups can be positioned and reordered based on the users needs. This area also populates when columns are programmatically added as groupDescriptions on the DataGrid as well.

Using Group Descriptions Example

Hierarchical Groups

The groupHeaderDisplayMode property allows the groups to be hierarchical. By default, each group description that is added gets aggregated together. Setting the groupHeaderDisplayMode to Split will create a section header for ever group defined in groupDescriptions property of the IgrGrid.

import { GroupHeaderDisplayMode } from 'igniteui-react-core';

public componentDidMount() {
    // ...
    this.grid.groupHeaderDisplayMode = GroupHeaderDisplayMode.Split;
}

Collapsable Groups

Also, the IgrGrid can display a toggle on each group section to allow the end user to expand or collapse the grouped data via the isGroupCollapsable property.

public componentDidMount() {
    // ...
    this.grid.isGroupCollapsable = true;
}

Summary

For your convenience, all above code snippets are combined into one code block below that you can easily copy to your project.

import { IgrColumnGroupDescription } from 'igniteui-react-grids';
import { ListSortDirection } from 'igniteui-react-core';
import { GroupHeaderDisplayMode } from 'igniteui-react-core';

public componentDidMount() {
    window.addEventListener('load', this.onLoad);
}

public onLoad() {
    const state = new IgrColumnGroupDescription();
    state.field = "Country";
    state.displayName = "Location";
    state.sortDirection = ListSortDirection.Descending;
    const city = new IgrColumnGroupDescription();
    city.field = "City";
    city.displayName = "";
    const income = new IgrColumnGroupDescription();
    income.field = "Income";
    income.displayName = "Income";

    this.grid.groupDescriptions.add(state);
    this.grid.groupDescriptions.add(city);
    this.grid.groupDescriptions.add(income);

    this.grid.isGroupCollapsable = true;
    this.grid.groupHeaderDisplayMode = GroupHeaderDisplayMode.Split;
}
