Data Grid

Focused Row

Documentation

This example demonstrates a DataGrid widget that supports focused rows. The focusedRowKey option specifies the focused row. The onFocusedRowChanged callback function can be used to display additional information below the DataGrid when the focused row changes. The focusedRowEnabled option enables row focusing.
