Focused Row

The DataGrid 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 DataGrid automatically scrolls to the focused row if the autoNavigateToFocusedRow property is enabled. In the UI, users can click a row to focus it. The focused row is saved in the DataGrid's state.

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