title: How to validate a text box based on radio button selection in ASP.NET MVC 3 and JQuery?
body: <p>I have a radio button with values, "Yes" and "No". If user selects "Yes", the text box slides down. So it has to be validated. If user clicks "No", the textbox slides up and there is no need for validation.</p>
  
  <p>I tried to use, ValidationMessageFor(model => model.TextBoxValue), but I am not able to submit the form as, it validates the text box even it is slided up.</p>
