  <p>There are 4 toggle buttons, when I be click on one, the other 3 are not clicked
  For example, when I click public, Confidential's Click will be removed. Only 1 can be selected.</p>
  <pre><code> &lt;toggleButton id=&quot;textButtonpublic&quot; getLabel=&quot;getpublic&quot; getImage=&quot;getcolor&quot; onAction=&quot;PublicAction&quot; getVisible=&quot;getvisiblepublic&quot;  getPressed=&quot;GetPressedPublic&quot;   /&gt;
  
  public void PublicAction(IRibbonControl control, bool pressed){
  GetPressedConfidential();}
  
  
   public bool GetPressedConfidential(IRibbonControl control)
      {
          return false;
      }
  </code></pre>
  <p>It didn't work when I called the GetPressedConfidential method.</p>
