title: ASP.NET: avoid RequiredFieldValidator on navigate button postback
body: <p>I have an ASPX page with two RequiredFieldValidator and a button to go to another page. This button must do a postback to know where to go. This button can be clicked it any time.</p>
  
  <p>The problem is that the RequiredFieldValidators are not disabled and show their message asking for a value.</p>
  
  <p>Is there any way to avoid validation when the user click this special button?</p>
  
  <p>Thank you!</p>
