This first real post in the SharePoint 2010 Ribbon Controls series (full series index available here) will be about some of the common properties that most or all of the Ribbon controls shares. I assume that you have some basic knowledge of SharePoint 2010 Ribbon customization, if not check out one of my previous posts.
What is a Ribbon control? A SharePoint 2010 Ribbon Control is the interactive parts of the Ribbon. Controls exits within a Group (B) within a Tab (A). The controls can be labels, buttons, drop downs, menus, galleries and more. You can add, remove or change default Ribbon controls or add completely new Tabs and Groups.
