Editable Grid

With this design if a user selects a checkbox and rest checkboxes are disabled, wont it be an inconvenience that user cannot select another checkbox?

Try this example

a!localVariables(
  local!employees: {
    a!map(id: 1, name: "Ravi", role: "Developer"),
    a!map(id: 2, name: "Priya", role: "Tester"),
    a!map(id: 3, name: "Arun", role: "Manager")
  },
  local!selectedRow: {},

  a!gridLayout(
    label: "Select Only One Row",
    headerCells: {
      a!gridLayoutHeaderCell(label: "Name"),
      a!gridLayoutHeaderCell(label: "Role")
    },
    rows: a!forEach(
      items: local!employees,
      expression: a!gridRowLayout(
        id: fv!item.id,
        contents: {
          a!textField(
            value: fv!item.name,
            readOnly: true
          ),
          a!textField(
            value: fv!item.role,
            readOnly: true
          )
        },
        selectionDisabled: and(
          length(local!selectedRow) > 0,
          not(contains(local!selectedRow, fv!item.id))
        )
      )
    ),
    selectable: true,
    selectionValue: local!selectedRow,
    selectionSaveInto: a!save(local!selectedRow, a!flatten(save!value))
  )
)
