Hosted control types, action, and event reference in Unified Service Desk

This section provides information about the various types of hosted controls in Unified Service Desk, and the predefined User Interface Integration (UII) actions and events available for each hosted control type. You can also view information about the predefined UII actions and events for hosted controls in the embedded help in Unified Service Desk. More information: View embedded help for actions and events

Apart from the predefined hosted control types, this section also provides information about a custom hosted control, Session Timer, that becomes available when you deploy one of the sample Unified Service Desk applications on your Dynamics 365 instance. More information: Session Timer (Custom Hosted Control)


Most of the predefined hosted controls in Unified Service Desk have a predefined action called default, which calls an action on the hosted control that’s marked as the default. Because none of the predefined actions for any of the predefined hosted controls are marked as default, calling the default action on any predefined hosted control just loads the respective hosted control. However, for a custom Unified Service Desk hosted control, you can define an action and set it as default so that the action is called when the default action is called on the custom hosted control.
