I am trying to validate the dropdown as its value changes, however the validation is not firing until the the focus is lost from the control, until you unclick from it. Even if the selection is valid, "This field is required." message still appears until the control loses focus. What should I do to have it validated so that the "This field is required" error message is gone as soon as the selection is made from the dropdown?
