Data Grid - 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.

In this demo, the row with the 117
key is focused initially. You can specify the focusedRowKey
and autoNavigateToFocusedRow
properties via the input field and the checkbox below the DataGrid.
