Hello Chandana,

The RadMenuItem uses a ButtonChrome control that is responsible for visual states. To change one of its state , you need to edit the Style for the ButtonChrome and apply the new Style to the ButtonChrome inside the RadMenuitem template.

The information in the article is a bit outdated, for which I hope you can accept our apologies. We will update that described approach as soon as possible.

For now, I prepared a very basic sample that has a changed mouse over state for both the top level item and submenu item. Some useful information on the topic can be also found here.

I hope this helps.

Kind regards,
Dani
