Angular Data GridTree Data - Overview

Enterprise

Tree Data provides a way to supply the grid with structured hierarchical data.

Enabling Tree Data

To enable Tree Data set the treeData property to true in the grid options, and provide a getDataPath callback to configure the Row Hierarchy

The example above uses the following configuration to enable Tree Data:

<ag-grid-angular
    [treeData]="treeData"
    [getDataPath]="getDataPath"
    /* other grid options ... */ />

this.treeData = true;
this.getDataPath = data => data.path;
