    I have a field set to required field validation.But had input given to that field is just  a "Spacebar".

    And the field does not contain any value in it and able to submit the form with empty field.

    How to prevent this... Yaa I can go and use the java script to loop through required fields but then what is use of the required field.

    Hello Chatra,

    The Kendo UI Validator required validation rule tries to mimic the built-in browsers validation behavior - which you can check in this sample test page. However, you may override the built-in required rule and implement it as to fit in your scenario. For example:

      <input name="input" required/>
      <button>Click me</button>
        rules: {
          required: function(input) {
            if (input.filter("[required]").length && $.trim(input.val()) == "") {
              return false;
            return true;
