$(document).ready(function () {
    $("#Upctextid").keyup(function () {
        if ($(this).val() != " ") {
            $("#activate-step-2").removeAttr('disabled');
        } else {
            $("#activate-step-2").attr('disabled', 'disabled');
        }
    })
});

Thank you very much I used the keyup with you code and it works perfectly.

I didn't use blur as it is didn't work in a time user type in the box

 $("#Upctextid").keyup(function () {
        //get the current fields DOM element
        var myVal = $(this)[0];
        //strip all of the spaces from the field's value and see if it is empty
        if (myVal.value.replace(/ /g, '') === "") {
            $("#activate-step-2").prop('disabled', 'disabled');
        } else {
            $("#activate-step-2").prop('disabled', false);
        }
    });
