If I selected one row in editable grid then it should deselect all other rows except selected row

Stefan Helzle already provided a solution for the Editable grid.

However, If you are not doing inline editing in the grid, go with the Read-Only Grid. It has a configuration parameter to control max selection (maxSelections).

    selectable: true,
    maxSelections: 1,
    selectionValue: local!selection,
    selectionSaveInto: local!selection

a!localVariables(
  local!items: {
    {item: "Item 1", qty: 1, unitPrice: 10},
    {item: "Item 2", qty: 2, unitPrice: 20}
  },
  local!selected: tointeger({}),
  a!gridLayout(
    label: "Products",
    instructions: "Selected: " & local!selected,
    headerCells: {
      a!gridLayoutHeaderCell(label: "Item"),
      a!gridLayoutHeaderCell(label: "Qty"),
      a!gridLayoutHeaderCell(label: "Unit Price"),
      a!gridLayoutHeaderCell(label: "Total", align: "RIGHT")
    },
    rows: a!forEach(
      items: local!items,
      expression: a!gridRowLayout(
        id: fv!index,
        contents: {
          a!textField(
            value: fv!item.item,
            saveInto: fv!item.item

    /* Flatten the selected values so the result is easier to work with */
    /* when the select/deselect all option is used in an editable grid  */
    selectionSaveInto: {
      a!save(

Hi Stefan Helzle ,
You previously provided a link about limiting the number of rows in a grid field. However, my requirement is different: I have a large amount of data in an editable grid, but I want the grid to behave so that when one row is selected, all other rows are automatically deselected.
