title: The page is validated automatically after I set a validator and every time I want to redirect to another page, I get the error from validator?
body: <p>I though I have finished working on the page, however, after another round of checking, it seems that the previous working link is not working anymore and every time when clicked, tries to validate the page.</p>
  <p>The link is a part of a main master page.</p>
  <p>Looks like the Post Back event called from the clicking on the link is trying to validate Date Pickers again.</p>
  <p>I have the following logic to build <code>CustomValidator</code> and <code>RadGrid</code>, where I validates <code>RadDatePickers</code>:</p>
  <pre><code>&lt;telerik:RadAjaxPanel ID=&quot;RadAjaxPanel1&quot; runat=&quot;server&quot;&gt;
