React Data Grid - Row Selection

In this demo, the DataGrid allows users to select only one row at a time. To enable this mode, set the selection.mode property to "single". Press Ctrl to unselect a row.

You can access the selected row data from the onSelectionChanged function. In this demo, this function fetches the selected row's information and displays it under the grid.
