Client script

Set all the fields Read Only based on selection of particular choice in a field (state = cancelled)

You can use an onChange Client script or UI Policy. Then use the code below:

var fields = g_form.getEditableFields();
for (var x = 0; x < fields.length; x++) {
    g_form.setReadOnly(fields[x], true);
}

function onLoad() {
    var stateValue = g_form.getValue('state');

    // Ensure this matches the actual value of the "Cancelled" choice in your state field
    if (stateValue === 'cancelled') {
        var fields = g_form.getEditableFields();

        for (var i = 0; i < fields.length; i++) {
            g_form.setReadOnly(fields[i], true);
        }

        // Optional: keep the 'state' field editable to allow reverting
        // g_form.setReadOnly('state', false);
    }
}

Is this for the Incident Table? If so there should already be an OOTB UI Policy for this named Make fields read-only on close (at least there was in my PDI).

If this is for another table, you could always copy that UI policy and apply it to a different table (Though creating each UI Policy action could get tedious).

Otherwise folusho's suggestion will be the quickest.
