In this example we have attached a specific behavior to each <b>RadComboBoxItem</b>. The behavior activates a <b>ZoomPopup</b> element each time
the mouse cursor hovers a given ComboBox item.
<br />
The same behavior could be successfully applied to each item which derives from <b>RadElement</b> / <b>RadItem</b>, i.e.<br />
<ul>
    <li>RadMenuItem</li>
    <li>TabItem</li>
    <li>RadButtonElement, etc.</li>
</ul>
