React Tree List - Focused Row

The TreeList component can highlight the focused row. To enable this feature, set the focusedRowEnabled property to true.

To focus a row programmatically, specify the focusedRowKey property. The TreeList automatically scrolls to the focused row. You can set the autoNavigateToFocusedRow property to false to deactivate this behavior. In the UI, users can click a row to focus it. The focused row is saved in the TreeList's state.

You can use the onFocusedRowChanging and onFocusedRowChanged properties to specify a custom function that is executed before or after a row is focused.

To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
Backend API

In this demo, the row with the 45 key is focused initially. You can specify the focusedRowKey property via the input field below the TreeList. The onFocusedRowChanged function is used to display additional information below the component when the focused row changes.
