The DevExpress ASP.NET Floating Action Button (ASPxFloatingActionButton) is a button that appears in front of a container (HTML element or a control) when an end user interacts with the container's elements.
The floating action button provides two types of actions.
Action - Executes the action once an end-user clicks the floating action button.
Action Group - The floating action button serves as a container for multiple actions. When pressed, the floating action button expands nested actions.
You can handle end users' actions and define the FAB. Refer to the FAB Actions topic for more information.
