How to trigger a cell change from within a component to update the grid data? (AG Grid - React)

I have a dropdown component within an Ag Grid. But when I change the value, the client-side data object doesn't change.

I'm triggering a function within the component when the dropdown is changed - but how can I tell the "parent" AG Grid to update it's data for that cell? (AG Grid automatically updates it's data when you're just changing text directly in a cell, not using a custom component.)

It seems to have something to do with using getValue(), but I can't seem to find the proper call in the documentation.

Are you using a Cell Renderer or Cell Editor to build the dropdown component?

If using a Custom Cell Editor, you must implement the getValue method otherwise the grid will not insert the new value into the row after editing is done.

See this implemented here:

const CustomCellEditor = forwardRef((props, ref) => {
  const [selectedValue, setSelectedValue] = useState('United States');
  const values = ['United States', 'Russia', 'Canada'];

  /* Component Editor Lifecycle methods */
  useImperativeHandle(ref, () => {
    return {
      getValue() {
        return selectedValue;
      },
    };
  });

  const onChangeHandler = (event) => {
    setSelectedValue(event.target.value);
  };
  return (
    <div>
      <select value={selectedValue} onChange={onChangeHandler}>
        {values.map((item) => (
          <option>{item}</option>
        ))}
      </select>
    </div>
  );
});
