Master-Detail API
DataGrid API allows you to implement custom expand/collapse logic for master-detail rows. This example uses the expandRow(key) and collapseAll(groupIndex) methods inside the onSelectionChanged event handler to allow you to expand only one row at a time.
Feel free to share demo-related thoughts here.
