Sets or gets the value of the selected option.

Setting the value property sets the Option with that value to be the selected option. You must set the value property to a value that exists in the options list.

To reset the radio button group to have no option selected, set the value property to null or undefined.

Getting the value property returns the value of the currently selected option. If no value is selected, the value property returns an empty string.


  • Changing a radio button group's value in code does not trigger an onChange event.

  • If a radio button group is connected to a dataset, setting the radio button group's value in code does not set the value of the connected field in the dataset. That means if you use the dataset to perform a submit, the value changed in code is not reflected in the submitted item.

  • To submit the new value using a dataset, set the field's value using the setFieldValue() function before performing the submit.
