Hi Rejz Arron,

By default, Checkbox selection is used for multiple Grid row selection. So, if you want to maintain only one selected row, you can achieve your requirement by using the “rowSelecting” event of the Grid component. Please refer to the below code example, the documentation link, and the sample link.

function rowSelecting(e) {

  if (grid.getSelectedRecords().length) {

    grid.clearSelection();

  }

}

Please get back to us if you need further assistance on this.
