Grouping Basics

The KendoReact Data Grid enables you to display grouped table data.

Getting Started

To enable grouping:

1. Set the groupable and group options of the Grid.
2. Handle the onGroupChange or the emitted onDataStateChange event.
3. Manually group the data. The Grid expects the grouped data to be a collection of GroupResults.

For more information, refer to the article on the process helpers for bulk data operations.

Grouping Columns Dynamically

By default, all columns of the Grid can be grouped multiple times. To enable the grouping of specific Grid columns and implement dynamic grouping to a column, use a function or a variable for the groupable property.

Copy Code<Column field="ProductID" filterable={false} title="ID" width="50px" groupable={this.isGroupable("ProductID")} />

Copy CodeisGroupable = (field) => {
    return !((this.state.dataState.group || []).find((g) => g.field === field));
}

Persist Groups Collapsed State

The data-tools package provides few utility methods which can be used to generate unique group items ids and use them to persist the group collapsed state.

Expand and Collapse all groups

The following example demonstrates how to add button to expand or collapse all groups in the Grid.
