title: Field validation of a single button only
body: <p>I have the following validator on a textbox inside a modal dialog box.</p>
  
  <pre><code>&lt;asp:RequiredFieldValidator runat = "server" 
                              ErrorMessage = "Role name can not be empty."
                              ControlToValidate = "tbxRoleName" /&gt;
  </code></pre>
  
  <p>It works like it should, except that the validation triggers on every other buttons OnClick handler on the aspx-page too. Since the dialog is invisible it looks like buttons just dont work on the page. My workaround is to add CausesValidation = "false" on all buttons on the page. But it is a very bad solution and I think there should be a smarter way.</p>
