Focused Row
Documentation
The DataGrid widget can highlight the focused row. To enable this feature, set the focusedRowEnabled option to true.
To focus a row programmatically, specify the focusedRowKey option. In the UI, users can click a row to focus it. To focus a row in code, specify the focusedRowKey option. The widget automatically scrolls to the focused row if the autoNavigateToFocusedRow option is enabled. The focused row is saved in the widget's state.
You can use the onFocusedRowChanging or onFocusedRowChanged option 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 options via the input field and the checkbox below the widget.
Feel free to share demo-related thoughts here.
