I have created a form using Kentico on-line form and applied the built-in "required" validation on it. Whenever a textbox is empty then a required validation is shown. Now, I have entered a value in the textbox and press tab from the keyboard but the required message does not disappear. I want to remove or hide the message from the form when the user enters a value in the text box before the submit button is clicked. How to resolve this issue?
