Posted by Xing Liu on 10/24/2014
You can customize the ribbon buttons by modifying some Sitecore items in the Core database. Check in the Sitecore Content Editor at the following path:
You will see all of the various buttons and strips located here. So, you can add / remove ribbon strips and buttons here, as shown in the screenshot below.
If you have custom buttons, you can also specify the custom handlers for those buttons, which will allow you to execute custom code when you click those buttons.
